New approach to FM FM 1 queue and its performance measures

الملخص EN

In this paper we discussed uncertainty in the classical queueing model M/M/1 assuming that arrival rate is a fuzzy number      ( / / ) min max  and service rate is a fuzzy number        min max / /  .

We have also discussed its performance measures which were also fuzzy numbers using the concept of ߙ - cuts.Finally we presented a numerical example showing the efficiency of this new approach.
