基于改进直觉模糊数的混合型多属性决策方法

为了解决混合型决策不同类型指标难于集结的问题,将实数、区间数以及语言变量转化为直觉模糊数形式,依据直觉模糊加权算术平均算子对各个指标进行集结,引入一种改进的得分函数对直觉模糊数进行排序比较。算例结果表明改进的得分函数是实用和可行的。

Hybrid Multi-Attribute Decision Making Method Based on Improved Intuitionistic Fuzzy Numbers

In order to solve the problem that different kinds of indexes was not to be combined in hybrid multiattribute decision making, real numbers, interval numbers and linguistic variable were transformed into intuitionistic fuzzy numbers. Every indexes were combined by intuitionistic fuzzy weighted arithmetic averaging operator. Moreover, improved score function was introduced to order intuitionistic fuzzy numbers. In the end, a numerical example illustrated the validity and applicability of the proposed method.
