Authors:Sangeeta Bhanja Chaudhuri, Manoj Majhi, Sougata Karmakar Pages: 1 - 17 Abstract: Communication Media (CM) play a significant role in OSH awareness and training for employees of organisations. As there is no guideline for selecting appropriate CM in a given context, the superiority of a particular CM over another for any specific OSH-AT program is solely judged by the individual's conscience and experience. Hence, the present review aimed to portray the advantages and disadvantages of different CM, their role in effective OSH awareness/training, and factors that determine the advantage of one CM over others in a specific scenario. The article highlights the research lacunae pertaining to the domain of CM's role in effective OSH based on available information in peer-reviewed published articles searched from 'Web of Science', 'Scopus' and 'Google Scholar' following the PRISMA-ScR model for review. The current review is expected to motivate and assist the OSH professionals in selecting an appropriate CM for delivering successful OSH awareness and training.

Authors:Brahim Lafifi, Ammar Rouaiguia Pages: 18 - 36 Abstract: This paper presents a reliability analysis of a shallow foundation solicited by a central vertical loading, using the classical limit equilibrium theory and the Hasofer-Lind reliability approach. A deterministic model represented by the Meyerhof equations and Holtz formula is used to compute the ultimate bearing capacity and the settlement of the foundation. The concepts of design of experiments and Response Surface Method (RSM) can be used for the evaluation of the performance functions by generating the approximate polynomials equations. In this study, unit weight, cohesion and friction angle of soil were considered as random variables for the bearing capacity, whereas, Young's modulus and Poisson ratio for the settlement. From the obtained results in terms of reliability index and design points, it is important to notice that the adopted method showed a satisfactory concordance with the author's methods applicable in the reliability problems.

Authors:Ke Yin, Haiyun Zhou, Jimin Chen, Chen Zhao Pages: 37 - 50 Abstract: Through the study of community security risks in a megacity by the application of the Dempster-Shafer theory, this paper develops an indicator system for the assessment of urban community security based on a combined array of both static and dynamic factors including natural disasters, man-made hazards, community administration and security support. A proper model was thereafter constructed in order to better solve the problems such as content inadequacy, insufficient indicators, model inaccuracy and other problems which are frequently brought forward in the former assessments made by others upon the static and dynamic factors, and then the model was applied in a case study of a megacity. The findings show that more effective improvements have been made by using the newly constructed model in the urban community security risk management.

Authors:Arman Alimardani, Reza Dashti Pages: 51 - 67 Abstract: In this paper, 'outage centre' has been defined as the building where repair crew are dispatched from to the failure location in order to restore power. This paper has proposed a practical model of optimal allocation of the outage centres to minimise outages cost and improve system reliability simultaneously. The stepwise approach to obtain the optimum site of the outage centre in a 'work location' has been presented. Finally, the implementation of the proposed model is discussed in a sample network which consists of 81 buses. Analysis of the indices sensitivity to parameters has been also carried out and discussed. Keywords: optimal allocation of the outage centre; travel time; electricity distribution company Citation: International Journal of Reliability and Safety, Vol. 15, No. 1/2 (2021) pp. 51 - 67 PubDate: 2021-12-13T23:20:50-05:00 DOI: 10.1504/IJRS.2021.119644 Issue No:Vol. 15, No. 1/2 (2021)

Authors:Arman Alimardani, Reza Dashti Pages: 68 - 88 Abstract: The analysis of various reliability measures of a computer network system comprising two load balancers (LB), five web servers (WB), and three database replica servers (DBRS) as a series parallel system with four subsystems working under k-out-of-n methodology is described in this paper. Failure rates of LB/WB/DBRS in all the subsystems are constant and follow exponential distribution, whereas the repair follows two kinds of distributions namely general and copula distribution. Using transition diagram, first-order partial differential equations are developed and solved using supplementary variable techniques and copula modus-operandi. The objective of the paper is to find main reliability indexes such as availability of the system, reliability of the system, mean time to failure and expected profit. The results are shown in tables and graphs through which we establish the effect of failure rate and repair rate on reliability physiognomies. Lastly, the analysis of results indicates that copula repair is more effective in availability and expected profit analysis.

Authors:Ashutosh Mishra, Meenu Singla Pages: 89 - 103 Abstract: Software fault predictions have great importance during maintenance and evolution of softwares. To upgrade the quality of the software, it is necessary to predict the faulty software modules. Previous research investigated was mainly focused on the binary classification of software class modules using different fault prediction techniques. However, much less work was done on the prediction of the number of faults. In this study, a descriptive technique called as Generalised Rule Induction (GRI) associations rule mining is proposed to identify the number of faults in the faulty class module. The proposed technique is implemented for five releases of open source Apache Ant project which is taken from PROMISE repository. The results show that the generated rules for the class modules containing single fault achieves better accuracy with fewer rules.

Authors:P. Vijaya Laxmi, E. Girija Bhavani Pages: 104 - 122 Abstract: Throughout this paper, efforts are being made to analyse the availability of the second optional service queueing system with two kinds of servers on hold. One is warm-standby and the other is cold-standby. First essential service (FES) is provided to all arriving customers and only some of them may further demand second optional service (SOS). Both operating and standby servers provide FES and SOS to customers. Replacing the warm-standby server with the failed main operating server may not be successful. Each time an operating server or a warm-standby server fails, it is quickly sent to a repair facility. The combined approach for two models is presented through the indicator function. We derive the steady-state solution of the model using matrix geometric method. The numerical results are shown in which several features of the system are evaluated for both models. A cost model is developed to determine the optimal service rates during the first essential and second optional services using particle swarm optimisation.
