机械系统可靠度分配的惩罚函数法

Penalty Function Method for Mechanical System Reliability Allocation

在可靠性理论研究过程中,系统可靠性分配是其重要组成部分,其分配方法分为等同分配法和非等同分配法。为了解决要求构成系统单元具有相同的花费函数的非等同优化分配法与工程系统实际不相符的问题,利用惩罚函数法对系统可靠度进行优化分配,对构成系统单元的花费函数不需要特殊要求,使模型更加真实的反映客观实际。

System reliability distribution method which distribution method is divided into equivalence distribution method and non-equivalent distribution method is an important part of the process of reliability theory research.In order to solve the problem that the non-equivalent optimal allocation method which requires the same cost function of the system unit is not consistent with the engineering system,the penalty function method is used to optimize the system reliability,and the cost function of the system unit is not required specially that these make the model more realistic.
