摘要
本文通过协调系统的当前造价与长远经济效益。分别给出了三种情况下表决系统最优可靠度的决策方法。其一是当表决系统的组成单元数目给定时各单元最优可靠度的决策:其二是当各单元可靠度给定时表决系统最优单元数目的决策;其三是同时进行最优单元数目与最优单元可靠度的决策,对应上述三种情况。文中分别提供了具体算例。
In this paper, methods for obtaining optimal reliability to k-out-of-n: G systems are presented in connection with the following three cases: (1)obtaining optimal component reliability r~* for a fixed number of components n,(2)obtaining optimal number of components n~* for a fixed component reliability r, and (3) obtaining optimal pair (n~*, r~*) simultaneously, reapectively through coordinating the costs and the long-term interests of the systems.The corresponding numerical examples are provided.
