摘　　要：以前在串—并联冗余系统可靠性的最优分配问题上 ,总是把部件的可靠度看成是一个确定的值。论文从另外的角度 ,在遗传算法的基础上 ,把部件的可靠性和平均失效时间看成是随机变量 。Previous research on the redundancy allocation problem for series parallel systems has focused on where component reliability is assumed to be an exact value.Based on the genetic algorithm is developed for these problem formulations and is demonstrated on an illustrative problem.This paper discusses alternative formulations which allow systems reliability and mean time to failure to be treated as random variables.

关 键 词：冗余系统 可靠性 最优分配问题 遗传算法 NP问题
