摘要：In this paper, we study an open queueing networkwith operating service stations suffering breakdowns.Stochastic modeling of Markov chains is applied to describe thesteady-state probabilities of the system. The steady-stateprobabilities are evaluated by matrix-geometric method.Performance measures including mean number in the system,mean waiting time in the system, blocking probability, failureprobability of working stations and reliable probability of thesystem are defined. Stability conditions of the system arederived in closed-form formulae. Disposition strategies andsensitivity analysis of the system with variation of specificparameters are investigated to make the system operate moreefficiently.
