| 摘 要： | 研究具有多维诊断参数系统的可靠性和检测策略问题.为了判定系统是正常还是异常,每隔一段随机时间对系统检测一次,检测结果有可能出现错误,而诊断参数是多维随机变量.系统处于正常和异常状态的时间分别服从参数不同的指数分布,系统的修理时间是连续型随机变量,检测周期为任意随机变量.利用概率分析、补充变量和最优化方法,导出了系统的可靠性指标和最优检测策略.

| Abstract: | This paper considers the reliability and inspection policies for a system with multivariate diagnostic parameters.The system is inspected once every random time T to know whether it is in normal or abnormal.The inspection can bring about wrong conclusions,and the diagnostic parameters of the system are random vectors.The failure time of the system is negatively exponential distribution with dissimilar parameters when it is in normal or abnormal,whereas repair time distribution and the distribution of T are continuous and general respectively.By using probability analysis,the supplementary variable technique and an optimization method,the reliability indices and optimal inspection policies are derived. |
