本文针对具有语言型、直觉模糊数和区间直觉模糊数三种评价信息的混合型多属性群决策问题,提出一种基于属性权重和专家权重均未知的决策方法.首先,定义新的转换函数,可将不同粒度的语言评价信息统一成区间直觉模糊数;然后,基于支持度确定未知属性权重,并在综合考虑区间直觉模糊数熵值和相似度的基础上,建立了一种新的专家权重确定模型;在将混合型决策矩阵转换成区间直觉模糊决策矩阵后,利用IIFWA算子依次集结个体决策矩阵,从而得出方案集的排序.最后,应用在ERP选优问题中,验证了方法的有效性.
In this paper, a hybrid multi-attribute group decision-making problem with three kinds of evaluation information of linguistic type, intuitionistic fuzzy number and interval intuitionistic fuzzy number is proposed, and a decision making method based on attribute weight and expert weight is unknown.Firstly, a new transformation function is defined, The linguistic assessment information of different granularity can be unified into the interval intuitionistic fuzzy number. Then, the unknown attribute weight is determined based on the support degree, and a new expert weight is established based on the consideration of the entropy and similarity of the interval intuitionistic fuzzy number After the mixed decision matrix is transformed into the interval intuitionistic fuzzy decision matrix, the IIFWA operator is used to build the individual decision matrix in turn, and then the ranking of the plan is obtained.Finally, Effectiveness.
