| 摘 要： | 研究了由2个不同型部件和一个修理工组成的冷贮备可修系统。针对两部件存在两种故障模式,两部件的工作时间和维修时间均服从指数分布,部件1不可修复如新和部件2修复如新且部件1具有优先权的情况建立了该类系统的一般模型,运用几何过程理论和补充变量法分析了该系统。给出了系统的可靠度的La-p lace变换式以及首次故障前的平均时间。

| Abstract: | A cold standby repairable system consisting of two different components and one repairman is studied.It is assumed that the working time and the repair time distributions of the two different components which are subject to two kinds of failure are exponentially distributed.And component 1 is given priority but it is not as good as new after repair while component 2 is as good as new.The system is analyzed using the geometric process and the method of supplementary variable.The reliability and the mean time to the first failure of the system are deduced. |
