研究了由两个不同元件和一个维修工组成的温储备系统，而且转换开关是不完全可靠的，即只要转换开关失效，系统立即失效。假设两个元件和转换开关的工作时间和维修时间均为指数分布，同时元件1比元件2具有优先维修权和使用权，它们均修复如新。由于转换开关担负着工作元件与备用元件之间的转换工作，因此它是系统的重要组成部分，在维修中具有优先权。在这些假设下，构造了掌控这个系统的马尔科夫过程，并且通过使用聚合随机过程和拉普拉斯变换，推导了一些重要的可靠性指标。最后通过数值例子陈述了模型的理论结果。

A warm standby repairable system consisting of two different units and one repairmanis was studied.The switch is not completely reliable,as long as the switch failure,system failure immediately.It is assumed that the work-ing time distributions and the repair time distributions of the two units and the transfer switch are both exponential,and unit 1 is given priority than unit 2 in use and repair.Both unit 1 and unit 2 are repaired“as good as new”.The switch taking change of the switching work between the working unit and the standby unit is an important part of the system and has the priority in repair.Under these assumptions,the Markov process governing the system is constructed and some important reliability indexes are derived by using the aggregated stochastic processes and the Laplace transform.Finally, a numerical example is given to illustrate the theoretical results of the model.
