摘　　要：研究了一类温贮备可修系统,该系统由两个不同型部件构成,且具有修理延迟。假定工作寿命,延迟修理时间和修理时间均服从指数分布,利用马尔科夫可修系统知识,不仅给出了系统的可靠度,首次故障前平均时间的结果,而且给出了各项稳态的可靠性指标的解析表达式,最后进行了实例验证。A warm standby system of two different components with delay replay are studied. It is assumed that the working life, the delay repair time and the repair time are all exponential distributions. Then, the reliability, the mean time to failure are analyzed by Markov process. And the analytical expressions of all steady-state reliability indexes are obtained. Finally, a simple model are given for testing these reliability indexes.
