摘要
针对属性权重完全未知,且属性值以直觉模糊集形式表示的多属性群决策问题,运用最大偏差法建立模型,求出属性的最优权重,利用得分函数将直觉模糊信息转化为实数信息,并运用WAA算子将所得的实数信息进行集结,从而对方案进行排序.最后通过一个算例说明了该方法的有效性和实用性.
This paper studies a kind of muhiattribute group decision making problems in which the information about the attribute weights are unknown completely and the attribute value are described in the forms of intuitionistic fuzzy sets. A linear programming model is constructed to generate the optimal weights for attribute and score function is used to transform the intuitionistic fuzzy information to real number information. And then WAit operator is used to generate the real number information to get the priorities of alternatives. Finally, an example is used to illustrate the feasibility and effectiveness of the proposed approach.
