摘　　要：根据我们在文献〔1〕提出的失效相关串联工程系统可靠度的估算方法,本文进一步研究了失效相关串联工程系统可靠度的最优分布问题,解决了在工程系统总可靠度约束下使其总投入最小和在工程系统总投入限制下使其总可靠度最大等优化问题。根据优化问题的极值条件,建立了求可靠度最优分布的迭代算法,并计算了若干例题。Based on the estimation method for the reliability of a failure-dependent series engineering system proposed in Reference [1] ,this paper studies further its optimal reliability distribution problem. Two optimization problems are solved. First is making the total pay-out of the engineering system be minimum when its reliability is restricted, and second is making the reliability of the engineering system be maximum when its total pay-out is constrained. The iteration procedures for finding the optimal reliability distribution is suggested according to the extremum conditions of the optimization problems. Several numerical examples show the validity of the iteration procedures.
