犹豫模糊多属性决策的M-TOPSIS法

Hesitant Fuzzy Multi-Attribute Decision-making Based on M-TOPSIS Method

犹豫模糊集由于允许隶属度用几个数值的集合来描述,对于处理决策者对决策的信息表现出犹豫和优柔寡断情形特别适合,成为不确定多属性决策的又一有力工具;针对属性值为犹豫模糊元的多属性决策问题,提出了一种改进的TOPSIS决策法——M-TOPSIS决策法.并通过实际应用例子说明所提出的方法的有效性和实用性.

Because membership degree can be described by a set of several numerical values, hesitant fuzzy set is very suitable to deal with the decision problem with decision makers having hesitant attitude, and it becomes another powerful tool for multiple attribute decision making. For the attribute value is multiple attribute decision-making problem of hesitant fuzzy elements, an improved TOPSIS decision method is proposed, named M-TOPSIS method. Finally a practical example is given to illustrate the validity and practicability of the proposed method.
