摘要
文中提出了一种基于层次分析的串联系统可靠性模糊分配方法。此方法以层次分析为基础,利用三角模糊数构造评判矩阵,并且通过调节隶属程度和决策者对决策的乐观程度指数进行模糊运算,使决策更加合理,最后引入熵权作为可靠性分配的依据。工程应用实例表明该方法具有较好的实用性及有效性。
A fuzzy reliability apportionment method for series systems is presented in the paper based on the analytic hierarchy process. With this method, the triangular fuzzy numbers are used to construct the judging matrix, the fuzzy calculation is done by adjusting the membership degree and the optimistic coefficient to make the decision-making more correct and the entropy weight is introduced as the final index of reliability apportionment. An application example is given to show the practicability and effect of the method.
