基于三维模糊向量的一种模糊决策方法

A Fuzzy Decision-making Method Based on Three-dimensional Fuzzy Vector

首先从三维模糊向量出发,给出了三维模糊向量的区间值截函数的定义,讨论了截函数的性质。然后利用区间值截函数给出了两个三维模糊向量比较可能度的定义,并利用这种可能度建立了基于三维模糊集的一种新的模糊决策方法。

First,starting from the three-dimensional fuzzy vector,the definition of the interval-valued cut function of the three-dimensional fuzzy vector is given,and the nature of the cut function is discussed.Then the interval-valued cut function is used to give the definition of the comparison prossibility degree of two three-dimensional fuzzy vectors,and a new fuzzy decision-making method based on three-dimensional fuzzy sets is established by using this degree of possibility.
