  • A study on MX/GB/1 retrial queueing system with Bernoulli vacation
           schedule and variable server capacity
    • Authors: S. Sasikala, K. Indhira, V.M. Chandrasekaran
      Pages: 263 - 277
      Abstract: In this paper, we have investigated bulk retrial queueing system with Bernoulli vacation schedule and variable server capacity. According to the variable server capacity bulk service rule, the server can serve a minimum of one customer and a maximum of <i>B</i> customers in a batch. After completion of a batch of service, if the orbit is empty, then the server will go for a vacation. After completion of each batch of service, if the orbit is non-empty, then the server either go for a vacation with probability <i>p</i> or resumes its service with probability <span style="text-decoration: overline">p</span>. If arriving customers finds the server is busy with service or on vacation, they are grouped and it termed as unsatisfied customers or orbit. Unsatisfied customers will retry its appeal for service after some time. We have presented steady state system equations for the proposed model. Also, we have obtained some important performance measures for this system. Further, we have given numerical justification for this queueing system.

  • Stochastic production scheduling model with generalised Pareto rate of
           production and Weibull decay
    • Authors: Dasari Madhulatha, K. Srinivasa Rao, B. Muniswamy
      Pages: 278 - 299
      Abstract: This paper addresses the development and analysis of an EPQ model with random production and deterioration. Here it is assumed that the life time of the commodity is random and follows a Weibull distribution. It is also further assumed that the production process is random and the number of units produced per a unit time follows a generalised Pareto distribution. The generalised Pareto distribution is capable of including different types of production rates. Assuming that the shortages are allowed and fully backlogged, the inventory level at any time 't' is derived. With suitable cost considerations the total production cost is obtained and minimised with respect to the production uptime and downtime. Through sensitivity analysis, it is observed that the production distribution parameters and deterioration distribution parameters have significant influence on optimal production schedules and total production cost. This model is extended to the case of without shortages.

  • Inventory system analysis for an operation theatre: a hospital case
           study
    • Authors: R.R. Pradeep, A. Prabukarthi
      Pages: 300 - 316
      Abstract: To effectively manage the inventory in a hospital operation theatre (OT) by classifying products, proposing the inventory cost model, and simulation study are inevitable This study focuses on inventory management of drugs and medical consumables in an OT of a hospital. The inventory was classified based on always better control (ABC) and vital essential desirable (VED) analysis. A mathematical model has been developed with the objective of minimising the total inventory cost. The inventory system of an OT has been simulated to measure the system performance. Out of 111 products used 37% products falls either in class A or Class V or both. The simulation results suggest an average daily inventory level to be maintained in an OT for critical products. Since healthcare industry requires 100% service level and deals with perishable items, shortage cost and expiry factor are considered. Simulation results provide insight on utilisation of critical resources.

  • Ranking of branded products using aspect-oriented sentiment analysis and
           ensembled multiple criteria decision-making
    • Authors: Kumar Ravi, Vadlamani Ravi
      Pages: 317 - 359
      Abstract: In this paper, we proposed a novel aspect-oriented sentiment analysis and combined it with an ensemble of well-known multiple criteria decision-making (MCDM) methods such as TOPSIS, VIKOR, PROMETHEE II, ELECTRE III and FMADM for comparing a given set of products and services. To demonstrate the effectiveness of the proposed approach, we performed comparative study of a set of mobile phones and digital cameras using customer feedback available on twitter and e-commerce customer reviews. Eventually, the final ranks of the products were obtained by ensembling five MCDM methods through simple majority voting. During the whole process, we contributed to the state-of-the-art into four folds: first, we developed a novel aspect-oriented opinion determination approach. Second, proposal of a hybrid aspect-level sentiment score computation approach. Third, we developed two domain ontologies in order to represent prominent aspects and their synonyms for mobile phone and digital camera. Finally, we combined aspect-oriented sentiment analysis with ensembled MCDM to perform aspect-level comparative study of a set of alternatives. Further, VIKOR sensitivity analysis is also performed. Eventually, a detailed visual analytics is presented on a geometrical analysis for interactive aid (GAIA) plane.

  • Psychological motivations on the revisit intention of international
           student travels to Malaysia's neighbouring countries
    • Authors: Shiva Hashemi, Azizan Marzuki, Shaian Kiumarsi
      Pages: 360 - 376
      Abstract: This research study aims to contribute to the literature on student travel behaviour by evaluating the relationship between psychological motivations and revisit intention Malaysia's neighbouring countries. Using a sample of 132 international students exiting in Malaysia, the influence of psychological motivations on revisit intention and the moderating effect of destination image in the relationship between psychological motivations and revisit intention were investigated. Partial least square (PLS), a variance based structural equation model was employed to analyse the data. The results showed that the motivations on the tourist destination image have a positive relationship and are supported. The path relationship also indicated a highly significant direct effect of the relationships between physical motivations, knowledge and social interaction on atmosphere, natural amenity, farm life and affective image. The findings illustrate the significance of direct effects and path coefficients.
