A queueing model for a non-homogeneous terminal system subject to BR992

AbstractThis paper deals with a non-homogeneous queueing model to describe the performance of a multi-terminal system subject to random breakdowns. All random variables involved here are indepenent and exponentially distributed. Although the stochastic describing the system's behaviour is a Markov chain, the number of states becomes very large. The main contribution of this paper is a recursive computational approach (see(5)) to solve the steady-state equations concerning the problem. It further generalizes the homogeneous model treated in [1]. In equilibrium, the main performance characteristics of the system are obtained. Finally, some numerical results illustrate the problem in question
