摘　　要：基于转换开关不完全可靠的情形,对由三个不同型部件组成的温贮备可修系统模型,假定开关寿命、失效后修理时间及部件的工作寿命、贮备寿命、故障后修理时间分别服从不同参数的指数分布,构建该系统的数学模型。依据马尔科夫过程理论中可修系统模型的研究方法,分析该系统的可靠性指标,得出系统的平稳结果、可靠度的Laplace变换和首次故障前平均时间的解析式。Based on the situation that the change-over switch is not completely reliable, for a warm standby repairable system with three different components, a mathematic model is set up under the distributions that the lifetime and the repair time after fault of switch, and the service life, standby life and repair time after fault of components obey exponential distribu- tion of different parameters respectively. Based on research measures of the repairable system in Markov process theory, the reliability index of the system is analysed, and the system stable results, Laplace transformation of the reliability and the ana- lytic expression of mean time before first failure are obtained.
