Simulation of a random fuzzy queuing system with multiple servers

Resumo

The paper considers a queuing system that has k servers and its interarrival times and service times are random fuzzy variables.We obtain a theorem concerning the average chance of the event “r servers (r ≤ k) are busy at time t”, provided that all the servers work independently. We simulate the average chance using fuzzy simulation method and obtain some results on the number of servers that are busy. Some examples to illustrate the simulation procedure are also presented.
