Abstract : The queueing model discussed here is a generalization of a model of an M/M/1 queue, modified as follows. The queue alternates between two phases I and II. In phase I, the arrival and service rates are lambda 1 and mu 1, whereas in phase II they are lambda 2 and mu 2. The successive lengths of time during which the queue is in phases I and II are independent, negativeexponential random variables with parameters s1 and s2 respectively. The paper discusses the following partial generalization of this model. Consider a single server queue, governed by an extraneous phase process. This phase process is assumed to be an irreducible, mstate Markov chain in continuous time, with only stable states.
