| 摘 要： | 研究了由n个部件和一个维修工组成的环形相邻2/n(F)可修系统的可靠性问题。假定每个部件的工作时间和维修时间均服从指数分布,故障部件可以修复如新,但组成系统的部件是马氏相依的。利用广义转移概率的定义和关键部件优先维修的规则,求得了该系统的状态转移概率矩阵。当n已知时,获得了该系统的可靠度等重要可靠性指标。

| Abstract: | A circular consecutive-2-out-of-n: F repairable system is studied. It is assumed that the working time and the repair time of any component are both exponentially distributed and any component after repair is as good as a new one, but n components in the system have homogeneous Markov dependence. Using the definition of generalized transition probability and the rule with priority to repair the key component, the state transition probability of the system is derived. When n is given, some important reliability indices of the system such as confidence level are obtained. |
