基于效用函数的三角直觉模糊数群决策方法

A Group Decision Making Method Based on the Utility Function of Triangular Intuitionistic Fuzzy Numbers

针对多属性群决策问题,提出了一种基于效用函数的排序方法。首先定义了三角直觉模糊数,提出了基于该三角直觉模糊数隶属函数、非隶属函数的效用函数和精确效用值。最后,通过实例分析说明了该方法的具体应用及计算过程。

Concerning the multiple attribute group decision making problems, the paper puts forward a kind of method hased on the utility function for ranking. First it gives the definition of triangle intuitionist fuzzy numbers, and then puts forward the definitions of the utility function and exact value based on the membership function, non-membership function of the triangular intuitionistie fuzzy numbers. Finally, through the analysis of examples shows the specific application and calculation process.
