一种区间直觉模糊信息集成的新方法

A New Method for Aggregating Information Based on Interval-valued Intuitionistic Fuzzy Sets

研究了属性权值完全未知且属性值为区间直觉模糊数的多属性决策问题.首先提出了一种将区间直觉模糊数转化为区间数的公式;然后,基于可能度法给出了一种新的客观赋权方法,并给出一种基于可能度的方案的排序方法;最后,通过实例证明了该方法的有效性和实用性.

This paper studies a kind of multi - attribute decision - making problems in which the information about the attribute weights are unknown completely and the attribute values are described by interval- valued intuitionistic fuzzy numbers. First we give a formula which transforms interval- valued intuitionistic fuzzy number into interval, then a new method for deciding objective weights is given based on possibility degree, and a new method based on possibility degree is given to get the priorities of alternatives. Finally, an example is used to illustrate the feasibility and practicability of the proposed approach.
