非瞬时检测系统的最优检测策略

摘要

研究非瞬时检测系统的检测策略问题,假定系统有2种工作状态(正常及异常)和1 种故障状态, 当系统工作时,为了判断系统是正常还是异常，每隔一段时间对系统检测一次 ，检测时间是任意连续型随机变量. 利用概率分析和补充变量方法，求出了系统的最优检测 周期和诊断参数的最优临界值.%In this paper, the optimal checking policies of a system are discussed . The system has 2 working modes (normal and abnormal) and a failure mode. When the system is operating, it is checked once every time period to make sure it is in normal or abnormal. And, the duration of checking is a general random variab le. The optimal checking cycle and diagnostic critical value of the system are o btained by using probability analysis and the supplementary variable technique.
