摘要
研究 2部件串联可修系统的一个模型。假定每个部件有 3种状态 :正常、异常和故障 ,系统故障时不需检测 ,工作时每隔一段时间对系统检测一次 ,以便发现每个部件是正常还是异常。利用概率分析、补充变量和最优化方法 ,不但求出了系统的可靠性指标 ,而且得到了系统最优检测周期的计算方法。数值例子说明这种方法是可行的。
This paper deals with a model of 2-unit series repairable systems. It is assumed that each unit has 3 modes(normal, abnormal and failure), and the system is inspected at a time to make sure that each unit is in normal or abnormal while it works, whereas it is not inspected when it fails. By using probability analysis, the supplementary variable technique and an optimization method, not only the reliability indices also the method for calculating optimal inspection cycle have been obtained. The numerical example is served for demonstrating the feasibility of the method.
