摘要
本文研究了有启动失效或在服务中失效的离散时间Geo/Geo/1可修重试排队系统,得到系统的嵌入马氏链及其遍历性条件.在此基础上,又得到了稳态下系统的各种性能分析指标及随机分解性质.最后,通过数值算例研究了失效参数对平均队长的影响.
A discrete-time Geo/Geo/1 retrial queue with two failure modes,i.e.,starting failures and server breakdowns during service,is studied in this paper.The Markov chain underlying the considered queueing system is investigated and its ergodicity condition is obtained.Based on these results,some performance measures of the system in steady-state and a stochastic decomposition result are derived. Finally,some numerical examples show the influence of the failure parameters on the mean orbit size.
