Abstract

We analyze the transient behavior of the M/M/1+D queue. Considering an Erlang distribution for customers’ waiting time, we approximate the real system by a Markov chain. We obtain the Laplace Transform of the transient probabilities in the approximated model and the Laplace transform of the main performance measures for the real system. We next analyze the busy period of this queue. One interesting insight is that the busy period of the unstable M/M/s queue has a finite coefficient of variation.
