摘要
研究了特殊状态需要特殊修理的可修系统的可靠性和诊断策略。假设系统有三种运行状态 :正常状态、异常状态、故障状态 ,有些异常状态和故障状态需要特殊的修理 ,系统处于哪个状态需要诊断才能知道。当系统开始正常工作状态后 ,每隔一段时间 u进行一次诊断 ,直到系统故障或被诊断为异常。利用概率分析和补充变量方法 。
This paper studies diagnostic policies of repairable system with special state and special repair. Assume that the system has three modes: normal, partial failure and total failure. Some partial failure and total failure need special repair. It must be diagnosed to make sure which state the system is in. When normal state begins, system will be checked once every time period u until system fails or it is checked in partial failure. By using probability analysis and supplementary variable method, the optimal checking cycle and stable reliability indexes are obtained.
