Abstract:
This paper deals with retrial systems where servers are subject to random vacations. So far, these systems were analyzed only by queueing theory and almost works assuming that the service station consists of one server and the customers source is infinite. In this paper, we give a detailed performance analysis of finite-source multiserver networks with repeated calls of blocked customers and multiple or single vacations of servers or all station, using Generalized Stochastic Petri nets. We show how this high level stochastic model allows us to cope with the complexity of such networks involving the simultaneous presence of retrials and vacations, and how stationary performance indices can be expressed as a function of Petri net elements.
