Computing Fuzzy Queueing Performance Measures by L-R Method

Abstract

This article shows that the {\it L-R method} introduced in this work is one of valid methods for computing performance measures of fuzzy queues. Using this calculation technique, we find the number of customers and the waiting time of a simple queue M/M/1 in fuzzy environment. L-R method has the advantage of being short, convenient and flexible compared to the well-known and called alpha-cuts method.
