Three units connected with an automatic changeover switch and human operator is handling the system. Together with the failure in super priority, priority and ordinary unit, the other important failures like deliberate failure and switch failure have been considered for study of mathematical model. All failure rates are assumed constant and follow exponential distribution however, the repair rate for partially failed state follow general distribution and complete failed states are repaired using Gumbel-Hougaard family copula (a joint probability distribution of general distribution and negative exponential distribution). The system is analysed using supplementary variable technique and Laplace transform. The various popular measures of reliability such as availability, reliability, mean time to failure (MTTF) and profit function has been calculated for particular values of failure and repair rates. Sensitivity analysis for different traditional measures has also been done. Computed results have been highlighted by tables and graphs.","PeriodicalId":306451,"journal":{"name":"Int. J. Math. Oper.

Under the failure analysis failure mode effect analysis (FMEA) approaches has been applied and the critical components of the considered system were identified on the basis of their risk priority number (RPN). The identification of critical components on the basis of RPN score results in confusion to system analyst as it becomes difficult to allocate appropriate risk priorities under same RPN scores. Also, importance among the probability of occurrence of failure (Of), severity (S), probability of non-detection (Od) are assumed to be of same importance, however, in real practical application there exists relative importance among these three factors. Therefore, to overcome such types of limitations of FMEA approach a fuzzy decision making system (FDMS) and grey relation analysis (GRA) approaches were applied. The ranking results so obtained were compared for better and intelligent decision making of risky components and the results were further supplied to maintenance management/reliability engineer of the considered system for planning and implementing the suitable maintenance policy accordingly.","PeriodicalId":306451,"journal":{"name":"Int.

This paper addresses the researches with delay in payment and presents pertinent information about developments and extensions of such models to provide an up-to-date review of the studies conducted.

The existence of secondary queue is possible only when server has limited services to provide, and the system has a characteristic of service surrender facility. The paper deals with the analytical study of such system in which the parameter of the primary queue is probabilistic while parameter of the secondary queue is considered totally uncertain. We are the first to apply fuzzy logic to deal with the secondary queue. The average waiting time in the system by a customer and service wastage rate has been explored in our study through fuzzy arithmetic using α-cut. The service wastage rate is helpful in finding the level of amount of instability in the system when the secondary queue is in existence and is fuzzified.","PeriodicalId":306451,"journal":{"name":"Int.
