摘 要: 研究具有 2类故障的可修系统的一个模型 ,假定系统工作时可能直接发生第 1类故障 ,也可能经过异常后发生第 2类故障 .系统故障时不需检测 ,系统工作时必须经过检测才能知道它是正常还是异常 ,并且检测时间是一个随机变量 .系统开始工作后 ,每隔一段时间对它检测一次 ,直到系统故障或者检测结果是系统处于异常状态为止 .利用密度演化方法 。 In this paper, a two failure mode system is discussed. It is assumed that while the system is working in a normal stage, it can enter failure 1 immediately or failure 2 after passing through an abnormal stage. Failure modes are self announcing modes whereas normal modes and abnormal modes are non self announcing modes. While the system is working, it is inspected once every time interval to make sure it is normal or abnormal until it fails, or until the result of inspection is that it is abnormal. The ...
