GSPN models of multiserver multiqueue systems

Exact results are presented for the average customer waiting and sojourn times in systems comprising a number of finite-capacity queues cyclically attended by several servers. The system behavior is described using generalized stochastic Petri nets (GSPN), and the performance indices are obtained numerically by means of GreatSPN, a software tool for the analysis of GSPN. The average waiting and sojourn times of customers in Markovian multiserver multiunique systems are computed exactly for the first time; they were previously estimated by other authors using approximate models.<<ETX>>
