  • Testing for detection of crack in rotor using vibration analysis: an
           experimental approach
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Many incidents of rotor failures are reported due to the development and propagation of the crack. Condition monitoring is adopted for the identification of symptoms of the crack at very early stage in the rotating machinery. Identification requires a reliable and accurate vibration analysis technique for achieving the objective of the study. The purpose of this paper is to detect the crack in the rotating machinery by measuring vibration parameters at different measurement locations. Design/methodology/approach Two different types of cracks were simulated in these experiments. Experiments were conducted using healthy shaft, crack simulated shaft and glued shaft with and without added unbalance to observe the changes in vibration pattern, magnitude and phase. Deviation in vibration response allows the identification of crack and its location. Initial data were acquired in the form of time waveform. Run-up and coast-down measurements were taken to find the critical speed. The wavelet packet energy analysis technique was used to get better localization in time and frequency zone. Findings The presence of crack changes the dynamic behavior of the rotor. 1× and 2× harmonic components for steady-state test and critical speed for transient test are important parameters in condition monitoring to detect the crack. To separate the 1× and 2× harmonic component in the different wavelet packets, original signal is decomposed in nine levels. Wavelet packet energy analysis is carried out to find the intensity of the signal due to simulated crack. Originality/value Original signals obtained from the experiment test set up may contain noise component and dominant frequency components other than the crack. Wavelet packets contain the crack-related information that are identified and separated in this study. This technique develops the condition monitoring procedure more specific about the type of the fault and accurate due to the separation of specific fault features in different wavelet packets. From the experiment end results, it is found that there is significant rise in a 2× energy component due to crack in the shaft. The intensity of a 1× energy component depends upon the shaft crack and unbalance orientation angle.

  • An integrated Bayesian–Markovian framework for ascertaining cost of
           executing quality improvement programs in manufacturing industry
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Typically, the budgetary requirements for executing a supplier’s process quality improvement program are often done in unstructured ways in that quality improvement managers purely use their previous experiences and pertinent historical information. In this backdrop, the purpose of this paper is to ascertain the expected cost of carrying out suppliers’ process quality improvement programs that are driven by original equipment manufacturers (OEMs). Design/methodology/approach Using inputs from experts who had prior experience executing suppliers’ quality improvement programs and employing the Bayesian theory, transition probabilities to various quality levels from an initial quality level are ascertained. Thereafter, the Markov chain concept enables the authors to determine steady-state probabilities. These steady-state probabilities in conjunction with quality level cost coefficients yield the expected cost of quality improvement programs. Findings The novel method devised in this research is a key contribution of the work. Furthermore, various implications related to experts’ inputs, dynamics related to Markov chain, etc., are discussed. The method is illustrated using a real life of automotive industry in India. Originality/value The research contributes to the extant literature in that a new method of determining the expected cost of quality improvement is proposed. Furthermore, the method would be of value to OEMs and suppliers wherein the quality levels at a given time are the function of quality levels in preceding period(s).

  • TQM practices and its performance effects – an integrated model
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Total quality management practices have been embraced by many quality-oriented firms around the world in order to improve performance in terms of quality, productivity, customer satisfaction and profitability. The purpose of this paper is to investigate the direct and indirect effects of TQM practices on various performance indicators specifically in the Indian manufacturing context. This paper focuses on developing an integrated model encompassing significant structural relations showing the linkage between TQM practices and multiple performance indicators – quality performance, customer satisfaction level, operating performance, employee performance, innovation performance, society results and financial performance. Apart from analyzing the direct relationship between constructs, the main purpose of this work is also to identify all the possible mediation effects of performance indicators on others using structural equation modeling (SEM). Design/methodology/approach An in-depth literature review was conducted to identify the key practices for the successful implementation of TQM in an organization as well as to explore TQM-performance effects. As a result, four TQM practices and seven performance indicators were identified. The data were collected from 260 Indian manufacturing organizations. After confirming the reliability and validity using exploratory and confirmatory factor analysis, the proposed hypotheses were tested using SEM. Findings Through testing the proposed hypothesized structural model, the direct and indirect effects of TQM practices have been examined. Moreover, this work developed an integrated model showing the interrelationships between TQM practices and performance indicators identified. The findings gave an insight that the effective implementation of TQM practices assists in reaping benefits in the every facet of an organization. By implementing these practices effectively, managers can expect to realize improvement in all these performance areas. Research limitations/implications This study is subject to certain limitations. Even if all variables were found to be reliable, valid and satisfactory non-response bias test results, the remote possibility of bias in the data might not be fully ruled out. There is a probability of occurrence of common method variance and common method bias, since the data for both dependent and independent variables were collected from the same respondents in the organization. Additionally data on performance indicators were based on the respondent’s assessment and awareness only. The mediating relationship between individual TQM practice and performance indicators can be investigated in future studies. Since society results are a necessity in future, the direct and indirect practices focusing toward this can be explored. In addition, there is a research scope to identify the moderating effect of contextual factors such as degree of TQM implementation, scope of operation and type of organization. Practical implications The findings of the research offer some potentially valuable insights into the relevance of TQM practices and its strong linkage on various performance indicators, through which the overall organization performance can be enhanced. By implementing these practices effectively, managers can expect to realize improvement in all these performance areas. Hence, the managers can adopt this approach to assess their organization’s level in the quality path and as a guideline in implementing TQM practices. They can also measure the impacts of TQM practices on multiple performance measures in order to evaluate their TQM initiatives. Especially the deployment of quality culture is a requisite to excel in the every facet of performance. The positive relationship between TQM practices and various performance indicators can motivate the managers to allocate resources in time, effort and capital for TQM implementation in pursuing quality, leading to customer retention and competitiveness. The findings of the study strongly suggest the need for the holistic implementation of TQM practices for the survival of the organization. Originality/value While there is a considerable volume of researches carried out to investigate the linkage between TQM and organization’s performance across the globe, still little is evidenced regarding the mediating effect of performance indicators on others, especially in the Indian manufacturing context. The present paper attempts to extend and add knowledge to this line of research and to bridge the gap and provide sufficient empirical evidence specifically in the Indian scenario. Thereby helps the organization to follow a guideline to improve the overall performance.

  • Critical factors of effective implementation of IT-enabled ISO-9000 QMS
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Although aligning information technology (IT) with quality management (QM) is a popular concept, it has not yet been properly, theoretically and empirically grounded. Therefore, the purpose of this paper is to identify critical factors for the effective implementation (CFEI) of IT-enabled ISO-9000 quality management system (QMS). Design/methodology/approach The primary field data were collected through a questionnaire survey of 381 small and medium enterprises (SMEs) in India. Exploratory factor analysis and confirmatory factor analysis were applied to check the reliability and validity of the data collected. First, using pattern matrix, 48 items (extracted from relevant literature) representing CFEI of IT-enabled ISO-9000 QMS were grouped into six latent variables (eigenvalue⩾1). Second, to test the relationship among CFEI, firm performance and competitive positioning, six hypotheses were formulated and tested using structural equation modelling (SEM) procedure. Findings The study results found that identified CFEI of IT-enabled ISO-9000 QMS, i.e. “strategic attributes” (β=0.517), “tactical attributes” (β=0.323), “operational attributes” (β=0.281), “organisational infrastructure and processes” (β=0.231), “system knowledge” (β=0.194), “alignment of system with firm’s strategy” (β=0.230), have a significant effect (p

  • A hybrid decision making framework for modified failure mode effects and
           criticality analysis
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Assessing the severity of failure modes of critical industrial machinery is often considered as an onerous task and sometimes misinterpreted by shop-floor engineer/maintenance personnel. The purpose of this paper is to develop an improved FMECA method for prioritizing the failure modes as per their risk levels and validating the same through a real case study of induction motors used in a process plant. Design/methodology/approach This paper presents a novel hybrid multi-criteria decision-making (MCDM) approach to prioritize different failure modes according to their risk levels by combining analytical hierarchy process (AHP) with a newly introduced MCDM approach, election based on relative value distance (ERVD). AHP is incorporated in the proposed approach to determine the criteria weights, evaluated in linguistic terms by industrial expert. Furthermore, ERVD, which is based on the concept of prospect theory of human cognitive process, is applied to rank the potential failure modes. Findings It is found that the proposed FMECA approach provides better results in accordance with the actual industrial scenario and helps in effectively prioritizing the failure modes. A comparison is also made to highlight the differences of results between the proposed approach with TOPSIS and conventional FMECA. Research limitations/implications This research paper proposes an improved FMECA method and, thus, provides a deep insight to maintenance managers for effectively prioritizing the failure modes. The correct prioritization of failure modes will help in effective maintenance planning, thus reducing the downtime and improving profit to the organization. Practical implications A real case of process plant induction motor has been introduced in the research paper to show the applicability of this decision-making approach, and the approach is found to be suitable in correct prioritization of the failure modes. Originality/value Severity has been decoupled into various factors affecting it, to make it more relevant as per actual industrial scenario. Then, a novel modified FMECA has been developed using a hybrid MCDM approach (AHP and ERVD). This hybrid method, as well as its application in FMECA, has not been developed by any previous researcher. Moreover, the same has been thoroughly explained by considering a real case of process plant induction motors and validated with cross-functional experts.

  • Joint optimisation of operation and maintenance policies in an urban
           ropeway transport systems context
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to propose a stochastic optimisation model for integrating service and maintenance policies in order to solve the queuing problem and the cost of maintenance activities for public transport services, with a particular focus on urban ropeway system. Design/methodology/approach The authors adopt the following approaches: a discrete-event model that uses a set of interrelated queues for the formulation of the service problem using a cost-based expression; and a maintenance model consisting of preventive and corrective maintenance actions, which considers two different maintenance policies (periodic block-type and age-based). Findings The work shows that neither periodic block-type maintenance nor an age-based maintenance is necessarily the best maintenance strategy over a long system lifecycle; the optimal strategy must consider both policies. Practical implications The maintenance policies are then evaluated for their impact on the service and operation of the transport system. The authors conclude by applying the proposed optimisation model using an example concerning ropeway systems. Originality/value This is the first study to simultaneously consider maintenance policy and operational policy in an urban aerial ropeway system, taking up the problem of queuing with particular attention to the unique requirements public transport services.

           using decision making approach
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to identify and prioritize prime just-in-time (JIT) elements in Indian healthcare sector based on the degree of importance and difficulty. This facilitates the implementation of JIT philosophy in healthcare services without any failure as well as provides quality services to patients at low cost. Design/methodology/approach JIT elements related to health care services have been sorted out from comprehensive literature survey. Moreover, important and difficult JIT elements have been ranked on the basis of score obtained by the quantitative method using statistical tools. Furthermore, validation and prioritization of important JIT elements based on the degree of importance have been computed using the analytical hierarchy process (AHP) and best worst method (BWM). Findings The present work provides important, difficult and easy to implement JIT elements in healthcare services. Besides, this work justifies the application of decision-making tool (AHP, BWM) for the prioritization of JIT elements in the health care sector. Practical implications The present study develops a deep understanding of JIT concepts in health care services. Furthermore, it motivates professionals for implementing JIT in healthcare services with healthy situation for both hospital and supplier. Social implications The present work is beneficial for all the dimensions of sustainable development (social, economic and environmental). The implementation of JIT with a proper understanding of its elements results in an improved patient care, lesser cost of healthcare delivery, time and better management of associated medical items. This work also facilitates the proper management of inventory items together with the reduction in various Lean wastes with the proper implementation of JIT in healthcare. The reduction in various associated wastes leads to cleaner surrounding and lesser environmental degradation. Originality/value This paper outlines the need of a robust JIT approach in the healthcare sector for quality services. The efficacy of JIT, AHP and BWM has been explored to find out critical elements for successful JIT implementation in health care.

  • Performance modeling and optimization for complex repairable system of
           paint manufacturing unit using a hybrid BFO-PSO algorithm
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to optimize the performance for complex repairable system of paint manufacturing unit using a new hybrid bacterial foraging and particle swarm optimization (BFO-PSO) evolutionary algorithm. For this, a performance model is developed with an objective to analyze the system availability. Design/methodology/approach In this paper, a Markov process-based performance model is put forward for system availability estimation. The differential equations associated with the performance model are developed assuming that the failure and repair rate parameters of each sub-system are constant and follow the exponential distribution. The long-run availability expression for the system has been derived using normalizing condition. This mathematical framework is utilized for developing an optimization model in MATLAB 15 and solved through BFO-PSO and basic particle swarm optimization (PSO) evolutionary algorithms coded in the light of applicability. In this analysis, the optimal input parameters are determined for better system performance. Findings In the present study, the sensitivity analysis for various sub-systems is carried out in a more consistent manner in terms of the effect on system availability. The optimal failure and repair rate parameters are obtained by solving the performance optimization model through the proposed hybrid BFO-PSO algorithm and hence improved system availability. Further, the results obtained through the proposed evolutionary algorithm are compared with the PSO findings in order to verify the solution. It can be clearly observed from the obtained results that the hybrid BFO-PSO algorithm modifies the solution more precisely and consistently. Research limitations/implications There is no limitation for implementation of proposed methodology in complex systems, and it can, therefore, be used to analyze the behavior of the other repairable systems in higher sensitivity zone. Originality/value The performance model of the paint manufacturing system is formulated by utilizing the available uncertain data of the used manufacturing unit. Using these data information, which affects the performance of the system are parameterized in the input failure and repair rate parameters for each sub-system. Further, these parameters are varied to find the sensitivity of a sub-system for system availability among the various sub-systems in order to predict the repair priorities for different sub-systems. The findings of the present study show their correspondence with the system experience and highlight the various availability measures for the system analyst in maintenance planning.

  • Managing risk for auto warranties
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is threefold: first, to analyse the existing work of warranty risk management (WaRM); second, to develop a generic WaRM framework; and third, to design a generic taxonomy for warranty hazards from a warranty chain perspective. Design/methodology/approach To understand the top warranty hazards, the authors designed a questionnaire, received 40 responses from the warranty decision makers (WDM) in the automotive industry in the UK and then analysed the responses. Findings The assembly process capability at suppliers is the top contributor to warranty incidents from the suppliers’ and original equipment manufacturers’ (OEMs’) viewpoints. The human error at different stages of the product lifecycle contributes to the occurrence of warranty incidents. The collaboration among parties, particularly, the accessibility to warranty-related data between parties (i.e. suppliers, OEM and dealers), is limited. Customers’ fraud contributes more to warranty costs than warranty services providers’ fraud. The top contributors to customer dissatisfaction relating to warranty are the warranty service time and service quality. Research limitations/implications The questionnaires were used to collect data in the UK, which implies the research outcomes of this paper may only reflect the UK area. Practical implications The WaRM framework and taxonomy proposed in this paper provide WDM with a holistic view to identifying the top contributors to warranty incidents. With them, the decision makers will be able to allocate the required fund and efforts more effectively. Originality/value This paper contributes to the literature by providing the first work of systematically analysing the top contributors to warranty incidents and costs and by providing a WaRM framework.

  • Understanding TQM implementation barriers involving construction companies
           in a difficult environment
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to identify the factors that affect TQM implementation in construction companies and it suggests solutions for TQM implementation in a difficult environment. Design/methodology/approach Studies were carried out at six large construction companies who ply their trade in Southern Africa and in-depth investigations were conducted to assess TQM implementation practices and associated TQM barriers. Interviews were conducted on directors and key personnel that play important roles in TQM implementation in their respective organisations. The empirical study also utilised a number of organisational documents which added rigour to the findings. Findings This study identified three core categories and ten main barriers affecting TQM implementation in Southern Africa construction companies. The core categories are motivation, infrastructure and penchants and tendencies while the factors are lack of quality support, poor TQM knowledge and TQM awareness, poor information sharing, temporary workers, overdependence on contract document, poor data collection measurement, undefined TQM roles and responsibilities, award to lowest bidder tendency, poor business environment and corruption. Research limitations/implications The study was conducted based on companies plying their trade in Southern Africa and mostly around Malawi, Zambia and Mozambique. It does not study companies in Namibia, Zimbabwe, Angola, South Africa and Botswana. Practical implications TQM cannot be exported wholly from another region to a new setting without taking into consideration the local factors associated with that setting. For successful TQM implementation in construction in Southern Africa, characteristics of this region have to be known. This study illuminates a number of TQM implementation barriers associated with construction especially applied to this difficult environment. Application of this knowledge would enhance TQM and heighten competitive advantage initiatives. The proportions highlighted in this study therefore help build up the TQM implementation awareness. Social implications At society level, the findings of this study indicate societal problems such as corruption and business environment which require wide level approaches to deal with these barriers. In addition, if TQM applied in road construction projects, the quality of the roads will be improved, this in turn will have direct impact on quality of life in the society, better roads means easier access to hospitals, schools and public places, better transport and movements of goods and services, etc. It can also save money for the country in long run and economic benefits to the society. Originality/value The factors identified in this study are based on current TQM implementation practices at established construction companies in Southern Africa. They provide a practical basis for guiding TQM in construction companies operating in difficult environments.

  • Acceptance sampling plans based on truncated life tests for Rama
           distribution
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Lifetime data are used in many different applied sciences, like biomedicine, engineering, insurance and finance and others. The purpose of this paper is to develop a new acceptance sampling plans for Rama distribution when the mean lifetime test is truncated at a pre-determined time. The minimum sample sizes required to assert the specified life mean is obtained for a given customer’s risk. The operating characteristic function values of the sampling plans and producer’s risk are calculated. Design/methodology/approach The results are illustrated using numerical examples and a real data set is considered to illustrate the performance of the suggested acceptance sampling plans and how it can be used for the industry applications. Findings This paper shows a new acceptance sampling plans based on Rama distribution in the particular case when the mean life time test is truncated. Originality/value The results calculated in this paper demonstrate the differences between OC values for different distributions taken into account. In particular, OC values of Rama distribution are found to be less than the proposed distribution counterparts.

  • Experimental design and analysis of matching design
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose This study considers the five factors of a car rotation system: angle (F1), arm length (F2), toe in and out (F3), width (F4) and length (F5). The purpose of this paper is to fine tune the design so it produces the smoothest response to various rotation angles. Design/methodology/approach In the case of Ackerman’s principle, the response surface methodology (RSM) was used to analyze data when encountering different quality characteristics at various rotation angles. Findings In this study, RSM was used to obtain the best factor and the best reaction value for the five factors of a car rotation system. Practical implications In this study, the four-wheel steering of a car is taken as an example. When the current wheel is turned, the intersection of the left and right wheels of the front axle falls on the extension line of the rear wheel. In this case, the steering will be the smoothest. In this example, we selected angle (F1), arm length (F2), toe in and out (F3), width (F4) and length (F5) as experimental factors, hoping to satisfy the Ackerman principle. Social implications Traditionally, when dealing with four-wheel steering problems, solutions may be based on past experience or on new information used to formulate R&D plans. In this study, the combination of statistical factors and optimization is used to find the optimal combination of factors and the relationship between factors. Originality/value In the past, most literature relied on kinematics to study the car rotation system due to a lack of experimental design and analysis concepts. However, this study aims to achieve the above goals in finding the solution, which can be used to predict reaction values.

  • Synergetic success factors of total quality management (TQM) and supply
           chain management (SCM)
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is twofold: first, to present a set of critical factors for total quality management (TQM) and supply chain management (SCM) practices through an extensive literature review; and, second, to identify the relationships among them by comparing the identified TQM and SCM practices in order to explore the concept of supply chain quality management (SCQM). Design/methodology/approach To meet the goals of this work, a review of published quality research papers was carried out. For this, the authors identified papers on TQM and SCM practices and observed how these practices improve the business performance of organizations. Further, on the basis of identified practices, a conceptual model of SCQM was developed. Findings The results presented a set of six critical factors each for TQM and SCM practices. Further, it was found that management support and commitment, customer focus, information and supplier partnership are the most common practices found in both TQM and SCM practices. The integration of TQM and SCM (SCQM) throughout the supply chain has the strongest impact on the organizational performance. Research limitations/implications The study used data from various research papers of reputed journals which considered the study of India’s manufacturing industry as well as other countries, which may not provide a clear picture. However, this can be overcome by applying the findings of this paper to collect data from Indian manufacturing industry in future studies. Practical implications Indian manufacturing industry can improve its competitive image through the synergy of TQM and SCM. The result of this paper will help in providing a greater understanding of identified TQM and SCM practices that will lead to the successful implementation of TQM and SCM strategies to enhance business performance in terms of the improved levels of customer service. Originality/value Much of the attention is given on TQM and SCM practices, and very few studies have been undertaken to integrate TQM and SCM practices. But as far as the authors know, there is no study undertaken to integrate TQM and SCM practices in India for the manufacturing class. Therefore, this study compares TQM and SCM practices and considers their integration and can be thus treated as filling a gap in the extant literature. Therefore, the findings of this review paper will contribute in future research.

  • Does IS0 9001 quality management system support product innovation' An
           analysis from the sociotechnical systems theory
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Building on the sociotechnical systems theory (STS), the purpose of this paper is to investigate the direct impacts of the social and technical QMs (ISO 9001) practices on both incremental and radical product innovation and the direct relationships relaying QMs (ISO 9001) as a sociotechnical system with incremental and radical product innovation. Design/methodology/approach The paper opted for a survey instrument to collect quantitative data from 82 Moroccan certified ISO 9001 firm. A partial least squares structural equation modeling (PLS-SEM) was used to test the research hypotheses. Findings Results show that the social and technical QMs (ISO 9001) practices do not have a significant relationship with incremental and radical product innovation when they are taken in isolation. However, when ranged together to constitute a whole sociotechnical system of QMs (ISO 9001), QMs (ISO 9001) prove to have a strong positive and significant impact on incremental product innovation and a weak positive and significant impact on radical product innovation. Research limitations/implications Because of the small sample size that might weaken the significance of the results and the use of cross-sectional data, this research may lack a large statistical generalizability vis-à-vis the analytical generalization. Practical implications The results provide useful implications for managers, suggesting that in order to develop their product innovation, they must ensure that both QMs (ISO 9001) social and technical practices achieve a high level of integration without allowing some quality practices to take over. Originality/value Based on the STS, this study is the first to focus primarily on the role of the multi-dimensional structure of QMs (ISO 9001), i.e. social and technical practices, in incremental and radical product innovation.

  • Supply chain management and organizational performance: the resonant
           influence
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose A single supply chain management (SCM) practice will have a certain impact on organizational performance (OP). However, since it is placed in a system that many other practices are conducted simultaneously, the practice itself will interact with other ones (i.e. affect/be affected). As a consequence, the efficiency of the affected practice is increased and it is expected to maximize the impact of SCM practices on OP. This mechanism is named the “resonant” influence that is a new approach in the SCM literature. The purpose of this paper is to test the above mechanism toward an insight into the relationship between SCM and OP. Design/methodology/approach Two models were compared: the competitive models only exist in direct effects; and the other contains relationships between practices that are able to show the mechanism of the resonant influence, i.e. the hypothetical model. A data set gained from Vietnamese garment enterprises was used to validate the mechanism of the resonant influence. Findings Empirical evidence from Vietnamese garment sector showed that the competitive models could explain 42.8, 26.3 and 34 percent variance of operational performance, customer satisfaction and financial performance, respectively. In the meantime, the hypothetical model containing the resonant influence is capable to explain 69.5, 33.1 and 57.3 percent. For the impact of each SCM practice on OP, all relationships in the hypothetical model are also greater than those in competitive ones. These results supported the mechanism of the resonant influence. Research limitations/implications This research provides an insight into the relationship between SCM practices and OP. By the resonant influence, the effectiveness of each affected SCM practice itself is magnified and OP is also increased remarkably. Practical implications Understanding the resonant influence, companies can apply this mechanism to enhance effectiveness of SCM practices at the lowest cost. To this end, the SCM practices should be implemented simultaneously as an integrated system rather than independent ones and the structural model proposed in this study is able to be used as “a guide map” for applying this mechanism. Originality/value This is one of pioneer empirical studies in the SCM literature that proposed and validated the concept of “resonant influence.”

  • Impacts of Lean Six Sigma on improving a higher education system: a case
           study
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to demonstrate the applicability and impact of Lean Six Sigma (LSS), a contemporary quality excellence methodology, for improving education system in a reputed University in Iran. Design/methodology/approach The paper follows a case study approach illustrating how theory has been put into practice, explaining how to implement the LSS define-measure-analyze-improve-control framework in a field-setting in a higher education institution (HEI), and to highlight the subsequent challenges occurred and lessons learned during the implementation. Findings The key finding from the study is the confirmation of LSS applicability in education systems. The goals of the LSS team were to baseline student satisfaction levels and improve the overall rating by 10 percent; to decrease student advising wait times by 15 percent; and increase enrollment by 5 percent. The application of the LSS methodology has delivered promising results to improve the education system of the University by achieving the set goals. Further, the implementation of LSS has demonstrated student-facing benefits of improved quality on the education system. Research limitations/implications LSS implementation in HEIs is relatively a new topic for research. Hence, this case study adds to the body of knowledge with directions to progress future research in this area. Practical implications The outputs of the case study have provided greater stimulus within the facilities for wider full-blown deployment of LSS as a strategic resource for problem solving. Additionally, this case study sets the foundation for many other future projects, and to trigger interest among the HEIs in their journeys for quality excellence. Social implications Higher education sector being a socially responsible field of service, LSS offers continuous improvement benefits, highlighted as part of this paper. Originality/value The applicability of LSS in HEIs is relatively an upcoming research area with immense potential and value. This paper would serve as a valuable means for both researchers and practitioners working in HEIs, in terms of understanding the systematic application of the LSS methodology, and implications in a real-world situation.

  • Lean thinking for education: development and validation of an instrument
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to respond to the increasing demands that education currently faces and develop a structured approach for the implementation of lean thinking (LT) in primary and secondary education (P&SE) and empirically validated it. Design/methodology/approach An extended literature review was conducted of studies on LT in education, service and manufacturing, in which a preliminary list was formed of LT dimensions, which were subsequently reviewed by a focus group. An instrument was generated, which was distributed to 1,400 education professionals, and 394 replies were received. The measures were tested for validity and reliability. After the first round of analyses, measures were tested further to strengthen the proposed instrument. Findings The findings confirmed that the instrument developed is both valid and reliable and that the proposed measures consist actual dimensions of LT in P&SE. A number of success factors that would be required for LT initiatives to be implemented effectively within the P&SE context in a holistic perspective were revealed. Practical implications Although a number of studies have been developed on LT in the manufacturing or service sector, its implementation in education and particularly in P&SE remains scant. The instrument developed provides sufficient knowledge of which are the most important dimensions to consider when pondering LT in education. Originality/value While LT has been the subject of previous research in education, this study represented the first look at lean in P&SE and was the first of its kind to develop and validate in a real environment a lean implementation instrument for use in educational institutions. Researchers and practitioners can use the proposed instrument to build models of facilitating practices to improve performance while contributing to economic growth and enhancing social empowerment.

  • The effect of transformer parameters on reliability assessment with the
           help of health index
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to study various reliability measures like reliability, mean time to failure (MTTF) and sensitivity of transformer including different parameters of insulating oil/paper as health index. Design/methodology/approach The reliability characteristics of transformer incorporating different parameters of insulating oil as well as paper have been evaluated using Markov process incorporating Gumbel–Hougaard copula, Laplace transforms and supplementary variable technique. The parameters taken into consideration are breakdown voltage (BDV) and moisture content (MC) of both insulating oil and paper, and other parameters considered are interfacial tension (IFT), dissipation factor (DF), degree of polymerization (DOP) and furanic content (FC) for insulating oil and paper, respectively. By probability consideration and continuity influence, difference-differential equations have been obtained for the considered model. Findings Transition state probabilities, reliability, MTTF and sensitivity of the transformer corresponding to different parameters of insulating oil and paper have been evaluated with the help of aforementioned technique. Variations of reliability with respect to time along with the variations of MTTF and sensitivity have also been examined. Remarkable points during the study have also been pointed out. Originality/value Reliability characteristics of the transformer have been evaluated including two parameters: insulating oil and paper with the help of supplementary variable technique, considering two different types of repairs incorporating Gumbel–Hougaard family of copula unlike done earlier. Reliability, MTTF and sensitivity of transformer have been analyzed considering the parameters: BDV, MC, IFT and FC of insulating oil, and BDV, MC, DOP, DF of insulating paper.

  • Acceptance X-bar chart considering the sample distribution of capability
           indices, [math] and [math]
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The traditional Shewhart control chart, the X-bar and R/S chart, cannot give support to decide when it is not economically feasible to stop the process in order to remove special causes. Therefore, the purpose of this paper is to propose a new control chart design – a modified acceptance control chart, which provides a supportive method for decision making in economic terms, especially when the process has high capability indices. Design/methodology/approach The authors made a modeling expectation average run length (ARL), which incorporates the probability density function of the sampling distribution of Cpk, to compare and analyze the efficiency of the proposed design. Findings This study suggested a new procedure to calculate the control limits (CL) of the X-bar chart, which allows economic decisions about the process to be made. By introducing a permissible average variation and defining three regions for statistical CL in the traditional X-bar control chart, a new design is proposed. Originality/value A framework is presented to help practitioners in the use of the proposed control chart. Two new parameters (Cp and Cpk) in addition to m and n were introduced in the expected ARL equation. The Cpk is a random variable and its probability function is known. Therefore, by using a preliminary sample of a process under control, the authors can test whether the process is capable or not.

  • Total Quality Management practices and work-related outcomes
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to explore the impact of Total Quality Management (TQM) practices on the performance of employees working in higher education institutions (HEIs). It also examines the mechanism through which TQM practices affect the performance of employees. Design/methodology/approach Data for the current study were obtained from both public and private sector HEIs of Pakistan. In total, 400 questionnaires were distributed among the administrative and academic staff of 3 universities and 240 usable questionnaires were received. Data were analyzed through regression analysis using SPSS. Findings The results show that the TQM positively and significantly determines employee performance, and the mediating variables of job satisfaction and affective commitment. Both the mediating variables show a mediating role in the TQM/employee performance relationship. Research limitations/implications The study has practical implications for universities’ top management to focus on TQM practices that help in building and enhancing satisfaction, commitment, as well as performance of the employees that could ultimately result in better performance of the universities. Originality/value This research is an addition to the current literature and the first attempt in this area to the best of authors’ knowledge. This study will help in identifying how important and beneficial it would be for the services organizations to implement the TQM practices and identifying the impact of TQM practices on employee’s job performance.

  • The relationships among transformational leadership, sustainable
           leadership, lean manufacturing and sustainability performance in Thai SMEs
           manufacturing industry
    • Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to examine the structural relationship model among transformational leadership, sustainable leadership (SL), lean manufacturing practices and sustainability performance. Design/methodology/approach The data were collected from the middle and senior managers working in small and medium enterprises of Thai manufacturing industry. Regarding the quantitative approach, the data were collected by means of survey from 598 respondents from 374 companies. Qualitative data were collected from 40 participants by participant observation, non-participant observation and in-depth interview. Findings The model reported that lean manufacturing has a partial mediate effect on the relationship between transformational leadership and sustainability performance, and between SL and sustainability performance. The structural model is different in automotive and nonautomotive companies, and the structural model is different among the companies which implemented lean program for less than five years and above five years. The data from in-depth interview informed that lean practices are appropriate for automotive industry though with less implementation in other industries. Firms pay most attention on customer involvement with some attention on employee and supplier involvement. Managers give advices and exchange ideas with their followers rather than inspiring and giving opportunities to make decision. Research limitations/implications The findings may also enable Thai managers to realize that lean practices are appropriate for any industry. The first thing to do before launching lean program to all process is that the company should buy-in the understanding of managers about lean concept and implementation. Willingness with well understanding and realizing importance of lean program will lead to superior results, especially operational, economic and sustainable performance. Originality/value The reliability and validity measurements confirmed that both SL and environmental and social performance are appropriate for manufacturing industries. This study provides evidence of the positive relationship between SL and lean manufacturing, lean manufacturing and sustainability performance, as well as the partial mediate effect of lean manufacturing on the relationship between SL and sustainability performance, which are the additional contributions to research in academic field. The results confirmed the positive relationship between transformational leadership and lean manufacturing. The results reported that there is difference of lean practices between automotive and nonautomotive companies, and between companies which implemented lean program less than five years and above five years. The structural relationship result reported that transformational leadership has effects on lean manufacturing whereas SL has no effect on lean manufacturing, which asserted the previous study in which one leadership model is more appropriate for success within lean implementations.

  • Communication of commitment towards sustainable development of certified
           Portuguese organisations
    • First page: 458
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is twofold: first, it aims at the identification and assessment of the commitments towards sustainable development (SD) communicated to all interested parties (stakeholders) by top management; and second, mapping the profile of the organisations which prominently communicate those commitments. Design/methodology/approach The research methodology was supported on the content analysis of the organisations’ statements (disclosed on the institutional website) that sustain the strategy and policies (organisational culture). A total of 540 certified Portuguese organisations in Quality, Environment and Occupational Health and Safety (QEOHS) comprised the sample. Findings According to this research, it is possible to identify three main commitments towards SD addressing customers (consumers), human resources (employees) and continuous improvement. Furthermore, results suggest that commitments towards customers and human resources fit properly into the theoretical assumptions of the stakeholder theory and, in turn, the commitment towards continuous improvement fits accurately into the assumptions of the “normative isomorphism” of the institutional theory. Moreover, the results pointed out the characteristics of Portuguese organisations (QEOHS) that prominently communicate commitments towards SD: large business volume, located in Lisbon or Setubal, fall within the public business sector, are members of the BCSD Portugal and publish annual reports on the institutional website. Research limitations/implications Solely organisations operating in Portugal and simultaneously encompassing three certified management subsystems (against the clauses of ISO 9001, ISO 14001 and OHSAS 18001 standards) were considered throughout this study. So it is not possible to ascertain at which extent the conclusions are valid. However, although the statistical generalisation of the results may be precluded, there is not any peculiar reason preventing the analytical generalisation, namely, in organisations operating in countries with similar macro-characteristics of Portugal. Originality/value To the best of authors’ knowledge this is the first time that such a comprehensive, detailed and thorough analysis of the communicated commitments towards SD is carried out regardless the activity sector. The conclusions from this paper are useful both for practitioners and scholars. On one hand companies have now information on the more often communicated statements, while on the other hand academics and scholars will benefit from this research and hopefully be able to replicate it in other contexts.

  • Enhancing human performance reliability in aircraft pushback operations
    • First page: 485
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to investigate the aircraft pushback operations to predict and manage human errors, particularly those associated with the complex team work of carrying out the pushback operation. This should improve air ramp operations reliability. Design/methodology/approach The study applied the human reliability assessment “Systematic Human Error Reduction and Prediction Approach” that involved a total of 60 semi-structured interviews with practicing experts. Past ramp accident reports were also reviewed to provide more in-depth insights to the problem. Findings Some of the key performance reliability-degrading errors identified relate to some frequent critical technical inabilities within the team of headset operator and tug driver, as well as the vulnerable intra-team communications. Several best practices were similarly identified. Practical implications Based on its findings, this study proposes a new technological concept that can help enhancing safety of aircraft pushback operations. This should enhance reliability of aircraft ground handling and improve aircraft availability. It also provided a generic methodological approach to improve safety-critical operations within high-risk industries. Social implications This study responses to the increasing trend in ramp accidents worldwide. Originality/value The research conducted to date in this area is still quite limited compared to that of flight and aircraft maintenance safety. The relevant existing studies focus more on ramp safety holistically, and do not go into the details of how safety and reliability of a ramp operation can be improved. The current paper aims at filling this gap.

  • Copula based constant-stress PALT using tampered failure rate model with
           dependent competing risks
    • First page: 510
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Accelerated life tests (ALTs) are used to make timely assessments of the lifetime distribution of highly reliable materials and components. Life test under accelerated environmental conditions may be fully accelerated or partially accelerated. In fully accelerated life testing, all the test units are run at accelerated condition, while in partially accelerated life testing, they are both run at normal and accelerated conditions. The products can fail due to one of the several possible causes of failure which need not be independent. The purpose of this paper is to design constant-stress PALT with dependent competing causes of failure using the tampered failure rate model. Design/methodology/approach Gumbel–Hougaard copula is used to model and measure the dependence between the life times of competing causes of failure. The use of the copula simplifies the model specification and gives a general class of distributions with the same dependent structure and arbitrary marginal distributions. Findings The optimal plan consists in finding optimum allocation of test units in different chambers by minimizing the reciprocal of the determinant of Fisher Information Matrix. The confidence interval for the estimated values of the design parameters has been obtained and sensitivity analysis carried out. The results of sensitivity analysis show that the plan is robust to small deviations from the true values of baseline parameters. Originality/value The model formulated can help reliability engineers obtain reliability estimates quickly of high reliability products that are likely to last for several years.

  • Statistically constrained economic design of [math] control chart with
           Weibull in-control time for processes subject to multiple assignable
           causes
    • First page: 526
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to develop an economic statistical design based on the concepts of adjusted average time to signal (AATS) and ANF for [math] control chart under a Weibull shock model with multiple assignable causes. Design/methodology/approach The design used in this study is based on a multiple assignable causes cost model. The new proposed cost model is compared with the same cost and time parameters and optimal design parameters under uniform and non-uniform sampling schemes. Findings Numerical results indicate that the cost model with non-uniform sampling cost has a lower cost than that with uniform sampling. By using sensitivity analysis, the effect of changing fixed and variable parameters of time, cost and Weibull distribution parameters on the optimum values of design parameters and loss cost is examined and discussed. Practical implications This research adds to the body of knowledge relating to the quality control of process monitoring systems. This paper may be of particular interest to practitioners of quality systems in factories where multiple assignable causes affect the production process. Originality/value The cost functions for uniform and non-uniform sampling schemes are presented based on multiple assignable causes with AATS and ANF concepts for the first time.

  • Reliability analysis of multi-state complex system with multi-state
           weighted subsystems
    • First page: 552
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to evaluate the reliability indices such as reliability, mean time to failure and sensitivity analysis. Design/methodology/approach A non-repairable multi-state complex system with two subsystems, namely, S1 and S2, is studied. The subsystems S1 and S2 are multi-state weighted r-out-of-n: G and s-out-of-m: G systems, respectively. Every component of the sub-system S1 consists of linear (f, l, k): G system, and the sub-system S2 consists of circular (f, l, k): G system. The subsystems are connected in series arrangement and components of these subsystems are arranged in parallel. Findings Markov stochastic process has been applied to obtain probability of components of the subsystems and various results discuss such as reliability, mean time to failure and sensitivity analysis with the help of the universal generating function. Originality/value In this work, reliability measures of the purpose system can be enhanced under the high profit.

  • Use of Basu-Dhar bivariate geometric distribution in the analysis of the
           reliability of component series systems
    • First page: 569
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to provide a new method to estimate the reliability of series system by using a discrete bivariate distribution. This problem is of great interest in industrial and engineering applications. Design/methodology/approach The authors considered the Basu–Dhar bivariate geometric distribution and a Bayesian approach with application to a simulated data set and an engineering data set. Findings From the obtained results of this study, the authors observe that the discrete Basu–Dhar bivariate probability distribution could be a good alternative in the analysis of series system structures with accurate inference results for the reliability of the system under a Bayesian approach. Originality/value System reliability studies usually assume independent lifetimes for the components (series, parallel or complex system structures) in the estimation of the reliability of the system. This assumption in general is not reasonable in many engineering applications, since it is possible that the presence of some dependence structure between the lifetimes of the components could affect the evaluation of the reliability of the system.

  • A hybrid EWMA chart using coefficient of variation
    • First page: 587
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to develop a new control chart using two EWMA statistics called the hybrid exponentially weighted moving average (HEWMA) chart to improve the sensitivity of EWMA chart proposed by Zhang et al. (2014). When mean and variance of process are not constants, the use of control chart using coefficient of variation (CV) is a successful approach. Design/methodology/approach The control chart using EWMA statistics has ability to detect moderate and small shifts in the process. The authors present the designing of the proposed HEWMA statistics control chart called the HEWMACV chart based on two hybrid EWMA (HEWMA) statistics. The proposed control chart utilizes the current information and previous information to make decision about the state of control chart. Findings In this paper, the authors will present the designing of HEWMA statistics control chart called the HEWMACV chart. The efficiency of the proposed control chart is shown using the simulated data and real data from the industry. The application of proposed chart on the real data shows that the proposed chart has ability to detect shift in the process and it is superior than existing chart in terms of average run length (ARL). Research limitations/implications The design and implementation of the proposed control chart on a real data shows that it can be applied in several industries, such as chemical industry, biological assays, etc. Practical implications The practical application of HEWMA chart using coefficient variation is gaining extensive adequacy. The design and implementation of the HEWMA chart offers a new approach in the detection of small process mean shift. Originality/value In practice, when mean and variance of process are not constants, the use of control chart using CV is a successful approach. In this paper, the authors designed a new control chart using two EWMA statistics called the HEWMA chart to improve the sensitivity of EWMA chart. The comparison shows that the proposed chart is superior than the existing chart in terms of ARL.

  • Loyalty intentions and selected relationship quality constructs
    • First page: 601
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to assess the mediating effect of customer engagement on the relationships between selected relationship quality and value antecedents (commitment, customer satisfaction, trust and customer value), and the consequence (loyalty intentions) within the short-term insurance industry. Design/methodology/approach A descriptive research design that is quantitative in nature was followed and 491 responses from insurance customers were analysed. Findings Short-term insurers should facilitate customer engagement by implementing strategies that foster customer commitment, ensure customer satisfaction, build trust and create customer value. Facilitating customer engagement may lead to stronger loyalty intentions amongst customers towards the short-term insurer. Research limitations/implications The investigation offers a greater understanding of the relevance and importance of the customer engagement theory and the impact it may have in strengthening the relationships between factors of the relationship marketing domain and customer loyalty. Practical implications From a managerial perspective, it is evident that short-term insurers should facilitate customer engagement carrying out strategies that foster customer commitment, ensure customer satisfaction, build trust and create customer value. Originality/value Building on the work of earlier relationship and quality management scholars, the study provides new insight into the role and relevance of relationship quality and value factors and customer engagement, while simultaneously being assessed for their contribution to customer loyalty.

  • Improved binomial and Poisson approximations to the Type-A operating
           characteristic function
    • First page: 620
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose In acceptance sampling, the hypergeometric operating characteristic (OC) function (so called type-A OC) is used to be approximated by the binomial or Poisson OC function, which actually reduce computational effort, but do not provide suffcient approximation results. The purpose of this paper is to examine binomial- and Poisson-type approximations to the hypergeometric distribution, in order to find a simple but accurate approximation that can be successfully applied in acceptance sampling. Design/methodology/approach The authors present a new binomial-type approximation for the type-A OC function, and derive its properties. Further, the authors compare this approximation via an extensive numerical study with other common approximations in terms of variation distance and relative efficiency under various conditions on the parameters including limiting cases. Findings The introduced approximation generates best numerical results over a wide range of parameter values, and ensures arithmetic simplicity of the binomial distribution and high accuracy to meet requirements regarding acceptance sampling problems. Additionally, it can considerably reduce the computational effort in relation to the type-A OC function and therefore is strongly recommended for calculating sampling plans. Originality/value The newly presented approximation provides a remarkably close fit to the type-A OC function, is discrete and needs no correction for continuity, and is skewed in the same direction by roughly the same amount as the exact OC. Due to less factorials, this OC in general involves lower powers than the type-A OC function. Moreover, the binomial-type approximation is easy to fit to the conventional statistical computing packages.

  • Copula-based reliability analysis of gamma degradation process and Weibull
           failure time
    • First page: 654
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is the reliability analysis for systems with dependent gamma degradation process and Weibull failure time. Design/methodology/approach Consider a life testing experiment in which a sample of n devices starts to operate at t=0 and the data are available on failure time and failure-evolving process on each individual, called in some contents wear or degradation. Ignoring the between performance characteristics dependency structure may lead us to different reliability estimations, while the dependency justly exists. In previous research, dependency between the degradation process and hard failure time has been studied in limited detail (special closed form expression). Thereafter, the dependency between two degradation processes with the same structure (gamma process) in a system is considered using the copula function. Findings The results indicate that ignoring the dependency structure may lead us to different reliability estimations while the dependency justly exists. Originality/value This study gives some contributions that evaluate reliability metrics with more than one failure mechanism that may not be independent and possibly follow a different distribution function. The authors have used the copula function as a basis to develop a proposal model and analysis methods. In addition, the authors discussed the identifiability of the copula. Finally, simulation data were used to review the suggested approach.

  • An application of integrated EPC–SPC methodology for simultaneously
           monitoring multiple output characteristics
    • First page: 669
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to develop an integrated engineering process control (EPC)–statistical process control (SPC) methodology for simultaneously monitoring and controlling autocorrelated multiple responses, namely, brightness and viscosity of the pulp bleaching process. Design/methodology/approach The pulp bleaching is a process of separating cellulose from impurities present in cooked wood chips through chemical treatment. More chemical dosage or process adjustments may result in better brightness but adversely affect viscosity. Hence, the optimum chemical dosage that would simultaneously minimize the deviation of pulp brightness and viscosity from their respective targets needs to be determined. Since the responses are autocorrelated, dynamic regression is used to model the responses. Then, the optimum chemical dosage that would simultaneously optimize the pulp brightness and viscosity is determined by fuzzy optimization methodology. Findings The suggested methodology is validated in 12 cases. The validation results showed that the optimum dosage simultaneously minimized the variation in brightness and viscosity around their respective targets. Moreover, suggested solution has been found to be superior to the one obtained by optimizing the responses independently. Practical implications This study provides valuable information on how to identify the optimum process adjustments to simultaneously ensure autocorrelated multiple responses on or close to their respective targets. Originality/value To the best of the authors’ knowledge, this paper is the first to provide application of the integrated EPC–SPC methodology for simultaneously monitoring multiple responses. The study also demonstrates the application of dynamic regression to model autocorrelated responses.

  • Fuzzy reliability analysis of the compressor house unit (CHU) system in a
           coal fired thermal power plant using TBGFLT technique
    • First page: 686
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to analyze the fuzzy reliability of the compressor house unit (CHU) system in a coal fired thermal power plant under vague environment by reducing the accumulating phenomenon of fuzziness and accelerating the computation process. This paper uses different fuzzy membership functions to quantify uncertainty and access the system reliability in terms of different fuzzy reliability indices having symmetric shapes. Design/methodology/approach This study analyses the fuzzy reliability of the CHU system in a coal fired thermal power plant using Tω-based generalized fuzzy Lambda-Tau (TBGFLT) technique. This approach applies fault tree, Lambda-Tau method, different fuzzy membership functions and α-cut coupled Tω-based approximate arithmetic operations to compute various reliability parameters (such as failure rate, repair time, mean time between failures, expected number of failures, availability and reliability) of the system. The effectiveness of TBGFLT technique has been demonstrated by comparing the results with results obtained from four different existing techniques. Moreover, this paper applies the extended Tanaka et al. (1983) approach to rank the critical components of the system when different membership functions are used. Findings The adopted TBGFLT technique in the present study improves the shortcomings of the existing approaches by reducing the accumulating phenomenon of fuzziness, accelerating the computation process and getting symmetric shapes for computed reliability parameters when different membership functions are used to quantify data uncertainty. Originality/value In existing fuzzy reliability techniques which are developed for repairable systems either triangular fuzzy numbers, triangle vague sets or triangle intuitionistic fuzzy sets have been used for quantifying uncertainty. These approaches do not examine the systems for components with different membership functions. The present study is an effort in this direction and evaluates the fuzzy reliability of the CHU system in a coal fired thermal power plant for components with different membership functions. This is the main contribution of the paper.

  • An investigation of the satisfaction of project managers and team members
    • First page: 708
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to compare the job satisfaction levels between International Organization for Standardization (ISO) 9001-certified and non-ISO 9001-certified project-based companies in Jordan, for project managers (PMs) and project team members (consultants, engineers and architects). Design/methodology/approach The study sample consists of individuals from the aforementioned four roles of ISO 9001-certified and non-ISO 9001-certified companies. A questionnaire survey was used to collect the data from 57 companies. In total, 72 valid questionnaires were returned, yielding a response rate of 92.98 percent. The data obtained were statistically analyzed, and then the independent t-test was used to test the study hypotheses. Findings The results revealed that ISO 9001-certified companies experience higher job satisfaction level for the four roles compared to non-ISO 9001-certified companies. Between the two samples, it was noted that there is a significant difference in the PMs’, consultants’ and engineers’ satisfaction with co-workers and without any remarkable difference in the specific satisfaction. No significant difference between the two samples in general satisfaction was found for PMs and engineers. Finally, no significant difference was found in three satisfaction elements for architects. Research limitations/implications Understanding the linkage between being ISO 9001-certified company and project members’ job satisfaction can provide a new strategic direction for project-based companies’ performance management that can help in achieving superior work outcomes. A small sample size is considered the main limitation of this study. Originality/value This study attempts to fill the knowledge gap that is rarely investigated in the literature, i.e. the link between being ISO 9001-certified company and the level of project members’ job satisfaction.

      Purpose Equipment reliability significantly impacts productivity, and in order to obtain high equipment reliability and productivity, maintenance and production decision should be made simultaneously to keep manufacturing system healthy. The purpose of this paper is to investigate the joint optimization of equipment maintenance and production decision for k-out-of-n system equipment with attenuation of product quality and to explore the impact of maintenance on the production and cost control for manufacturers. Design/methodology/approach A multi-period Markov chain model for k-out-of-n system equipment is set up based on the assumption that the deterioration of equipment is a pure birth process. Then, the maintenance cost, setup cost, inventory holding cost, shortage cost, production cost and the quality cost are analyzed with the uncertain demand and the attenuation of product quality stemmed from equipment deterioration. The total lowest cost per unit time and its specific calculation method are presented. Finally, the robustness and flexibility of the method are verified by a numerical example and the effects of equipment deterioration intensity and attenuation of product quality are analyzed. Findings The result shows that the joint decision model could not only satisfy the uncertain demand with low cost and strong robustness but also make the output products high quality level. In addition, the attenuation of product quality would influence the equipment maintenance and production decision and leads to the production waste and increases the operation cost greatly. Originality/value Implications derived from this study can help production maintenance managers and reliability engineers adequately select maintenance policy to improve the equipment efficiency and productivity with high quality level at a relatively low cost.

  • Reliability-based preventive maintenance strategies of road junction
           systems
    • First page: 752
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to present a study of reliability-centred maintenance (RCM), which is conducted on the key sub-assets of a newly constructed road junction infrastructure in Nigeria. Design/methodology/approach The classical RCM methodology, a type of RCM, which has a top down, zero-based approach for maintenance analysis, is implemented in this study. Findings The implementation of the classical RCM is successful in its application of various PM policies assigned to the assets and it shows that its application in the highway industry could reduce excessive maintenance backlog and frequent reactive maintenance by effective optimisation of its preventive maintenance (PM) intervals. Practical implications Road junctions are originators of more than 70 per cent of road traffic congestion and account for high accident rate. The traditional methods of reliability assurance used in the highway industry such as reactive maintenance and routine maintenance are often inadequate to meet the round the clock usage demands of these assets, thus the consideration for the application of a systematic RCM process for maintaining the system function by selecting and applying effective PM tasks. Originality/value It uses an approach that critically develops and analyses thoroughly preventive and continuous maintenance strategy in a new circumstance with environment of uncertainty and limited operating data. The case-based reasoning cycle has been applied in the RCM approach with real-time data obtained from a UK-based network maintenance management system for highway infrastructures.

  • Stochastic modelling and availability analysis of a critical engineering
           system
    • First page: 782
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to present the technique for evaluating the performance of a condensate system of a coal-based thermal power plant situated in the northern part of India. The data which used for system availability evaluation are not precise and are uncertain and, further, collected from concerned power plant history sheets and from discussion through plant personnel. Design/methodology/approach In the proposed model, traditional Markov birth-death process using a probabilistic approach is used to analyze the performance of a complex repairable condensate system of power plant up to a desired degree of accuracy. This approach has been demonstrated by breaking the condensate system into six subsystems arranged in series with two feasible states, namely, working and failed, labeled in a transition diagram and modeled as a Markov process, using Chapman–Kolmogorov equations, which are used for development of a probabilistic stochastic model for availability analysis in a more effecting manner, considering some suitable assumptions. Findings This study of analysis of reliability and availability can help in increasing the plant production and performance. The analysis is done with the help of availability matrices, which are developed using different combinations of failures and repair rates of all subsystems. To achieve the goal of maximum power generation, it is required to run the various subsystem of the concerned system of plant, failure free for a long duration. Therefore, the present approach may be a more powerful analysis tool to access the performance of all subsystems of a condensate system in terms of availability level achieved in availability matrices. The results of present study are found to be highly beneficial to the plant management for making maintenance decisions. Originality/value The present paper suggests a suitable technique for stochastic modeling and availability evaluation of an industrial system using Markovian approach and drawing a transition diagram to represent the operational behavior of the system. The present methodology includes the advantage of the ability to model and develop a more complex industrial system and helps in improving the performance and handling the uncertainties and possibilities of an industrial system.

  • Extending the service profit chain: the mediating effect of employee
           productivity
    • First page: 797
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose The purpose of this paper is to address the gap in the literature by extending the service profit chain (SPC) model and testing the validity of the proposed model in high-contact service contexts rather than by testing the key elements of the SPC in regard to a single business. Design/methodology/approach The study uses the exploratory factor analysis to identify a set of observables to use in representing the relationships included in the proposed extended model and employs the structural equation modeling to test the eight proposed hypothesis. Findings The study shows that the best-fit structural model supports the notion that employee internal service quality drives employee satisfaction that drives employee loyalty and employee productivity. In addition, employee productivity is shown as partially mediating the relationship between employee satisfaction and employee loyalty. Practical implications The results presented in this study have managerial implications and shed light on the importance of operational factors in the service industry, in particular high-contact services. Originality/value The integration of operations management and SPC still remain limited in the literature. Therefore, the study extends the SPC by integrating other operational factors, namely, employee productivity and internal service quality, and tests its validity in high contact services where the prolonged contact between the customer and the service system creates more opportunities to influence a customer’s perception of service quality.

  • Research gaps in Lean manufacturing: a systematic literature review
    • First page: 815
      Abstract: International Journal of Quality & Reliability Management, Ahead of Print.
      Purpose Literature contributions to Lean manufacturing (LM) are fragmented and show some significant limitations. The purpose of this paper is to identify the existing research gaps in LM as well as to group them into respective themes. Design/methodology/approach A systematic literature review (SLR) of peer reviewed journal articles in LM was carried out by the authors, based on four major publishers, namely, Emerald Online, Science Direct, Springer Link and Taylor & Francis. In total, 120 articles published in 30 journals during 2005–2016 were collected which revealed LM research gaps. A simple affinity diagram was applied in order to group the research gaps into logical themes. Findings A large number of research gaps are identified in the LM literature and meaningful themes of these gaps are also revealed. Research limitations/implications The SLR carried out by the authors is based on only four academic journal publishers and some of other publishers might have been missed out in this search. Excluding articles focusing on an individual Lean principle or tool/technique is also a limitation of the present SLR. Practical implications Researchers and practitioners can use the LM research gaps presented in this study for further development of LM methodology. Originality/value Presenting LM research gaps analytically and grouping them into meaningful themes, significantly differentiates the present SLR study from those published so far.
