摘要
针对属性权重信息完全未知且属性值以直觉模糊数形式给出的多属性群决策问题,提出了一种基于多准则妥协解排序的决策方法.利用直觉模糊加权平均算子集成所有的个体决策信息,以获取群决策信息.利用直觉模糊数熵权公式求得属性的熵权.依据传统VIKOR法的基本思想,结合直觉模糊数的距离公式,对备选方案进行排序择优.文中通过实例分析,表明该方法的实用性与可行性.
To solve the problems of the totally unknown attribute weights and the intuitionistic fuzzy numbers given to the attribute values,a decision making method based on VIKOR（Vlsekriterijumska Optimizacija I Kompromisno Resenje）is presented.Firstly,the group decision making information is obtained by using the intuitionistic fuzzy weighted averaging（IFWA）operator to aggregate all the individual decision making information.Then,the entropy weights of the criteria are obtained by utilizing the intuitionistic fuzzy entropy formula.According to the basic concept of the traditional VIKOR method and by means of the distance formula of intuitionistic fuzzy numbers,the alternatives are ranked,from which the best ones are picked over.Finally,the analysis of a numerical example proves the practicality and feasibility of the proposed method.
