可靠性分配本质上是一个工程决策问题,需要考虑的因素很多。这因素在早期设计阶段,在一定程序上都具有不确定性,而且很难甚至不能用经典数学进行描述。本文应用模糊集理论进行探索,提出了一种基于模糊综合评判的机械系统可靠性分配方法。 Reliability allocation is essentially an engineering decision-making problem, many factors need to be considered. This factor in the early design stage, have certain procedures are uncertain, and it is difficult or even impossible to use classical mathematics to describe. In this paper, the application of fuzzy set theory to explore, proposed based on fuzzy comprehensive evaluation of the mechanical system reliability allocation method.
