ANALYSIS OF PRIORITY QUEUES WITH PENTAGON FUZZY NUMBER
Keywords:Fuzzy Sets, Membership Functions, Priority Queues, Mathematical Programming, Pentagon and Trapezoidal Fuzzy Numbers, Performance Measures
Fuzziness is a sort of recent incoherence. Fuzzy set theory is asserted to depict vagueness. This study explores the queuing model of priority classes adopting pentagon fuzzy number with the inclusions of fuzzy set operations. A mathematical programming method is designed to establish the membership function of the system performance, in which the arrival rate and service rate of the system performance of two priority classes are utilized as fuzzy numbers. Based on -cut approach and Zadeh’s extension principle, the fuzzy queues are scaled down to a family of ordinary queues. The potency of the performance measures of the characteristics of the queuing model is ensured with an illustration and its graph.
