Online published on 2 March, 2017. Abstract In this paper, a multiple-server queue in rough environment is considered in which the arrival rate and service rate are rough interval numbers. A new method namely, multi-level method is proposed to determine the performance measures in the given queueing system as rough interval numbers. The solution procedure for the proposed method is demonstrated with the help of numerical example. The performance measures of the multiple-server queue in rough environment provided by the proposed method are rough interval numbers which are very much useful for decision makers for taking the managerial decision-making. Top Keywords Multiple-server queue, Rough interval numbers, Performance measures, Rough interval little formula, Multi-level method. Top | |
