串联系统可靠度优化分配

Optimal Allocation of Series System Reliability

目前系统可靠度优化分配只考虑系统的成本而忽视了系统的长远利益．针对这一问题，本文建立了系统的长远利益（损失期望）与可靠度间的函数关系，在此基础上提出了既考虑当前成本又考虑长远利益的串联系统可靠度优化分配方法，并给出了具体算例．

The cost is considered, but the long-term interests are ignored inoptimal alloction of system reliability at present. In view of this problem, thispaper provides the function relationship between long-term interests (lossexpectation) and reliability and presents a optimal series system reliability allocation method in which both the cost and the long-term interests are considered. A numerical example is given to illustrate the results.
