直觉模糊环境下基于记分函数和模糊熵的多准则决策方法

Decision-making method based on fuzzy entropy and score function under IF environment

本文在直觉模糊环境中并且各准则的权重完全不确定的情况下,提出了一种基于记分函数和模糊熵的多准则决策方法.由于一系列准则都是以直觉模糊集的形式给出的,因此本文建立了一个模糊熵模型,从而可以确定各准则的权重.在决策方法上首先利用直觉模糊点算子从未知信息中挖掘新信息,进而利用记分函数进行决策,不必分步也不用追加其它附加函数.文章最后用实例阐明该方法的有效性与优越性.

In the paper,a new multicriteria make-decision method is proposed based on the score function and fuzzy entropy weighted in the situation for intuitionistic fuzzy environment and completely unknown criterion weight information.As series of criterions are given in the form of intuitionistic fuzzy set,an entropy weight model is established to determine the criteria weights.In the decision-making method,a new point operator is firstly used to excavate new information in the unknown message so that decision is made by making use of score function.No substeps and no additional function else are needed.Finally the availability and superiority of the method are demonstrated in this paper by examples.
