一种基于散度的模糊数排序方法

引用一种距离测度及模糊数的权重面积,建立了一种基于散度的模糊数排序指标.新的排序指标不仅引入了两个参考对象,即两个模糊数的极大和极小(M),(N),同时还考虑了模糊数本身的影响和决策者的决策态度.排序方法不仅计算简单、易于操作,而且还具有良好的性质.算例分析表明本文所提出的排序方法在一定程度上克服了现有方法的缺陷.

Ranking Fuzzy Numbers Based on the Divergence

This article quotes a distance measure and weight area of fuzzy number,and establishes a ranking indicator of fuzzy number that bases on divergence. The new ranking indicator not only introduces two reference objects,which are maximum and minimum M,N of the two fuzzy numbers,but also takes the impact of fuzzy numbers themselves and the attitude of policy maker in decision-making into account. The sort method is simple to calculate,easy to operate,but also has a good nature. Example analysis shows that the r...
