摘　　要：利用可靠性理论,研究了两个不同型部件和一个修理工组成的可修型温储备系统。假设两个部件的工作寿命、贮备寿命、故障后的修理时间和贮备故障后的修理时间均服从不同的指数分布,在工作故障和贮备故障都不能"修复如新"的情况下,运用几何过程理论、拉普拉斯变换和补充变量方法得出该模型的一些可靠性指标。By using reliability of the basic theory,this paper studies a warm standby system consisting of two different components and one repairman is studied.Assume that two components of working time,standby time,the repair time after fault and the repair time after standby fault are subject to the different exponential distribution,in the situation where the repair failure and the standby failure can not ＂repair of non-new＂ at work,by using geometric process theory,the supplementary variable method and Laplace transform,the reliability indices of model are finally obtained.
