具有人类失效和关闭准则的三部件系统的可靠性分析

Reliability Analysis of a Three-Unit System with Human Failure and Shut-Off Rule

本文讨论了一类具有人类失效和关闭准则的三部件系统的两种可靠性模型。通过利用Markov更新和交替更新理论,我们获得模型Ⅰ和Ⅱ中系统可用度和在(0,t]内系统失效次数的期望值,还得到了模型Ⅱ中系统首次失次数的期望值,和模型Ⅱ中系统首次失效前的时间分布。

Two reliability models of a three-unit system with human failure and shut-off rule are discussed in this paper. By using Markov renewal theory and alternating renewal thrcory. We obtain the system availability and the expectation of system failure numbers in the interval (0,t] in model Ⅰ and model Ⅱ, and obtain the first system failure time distribution in model Ⅱ.
