摘要: 针对专家评价信息具有混合多属性且权重未知的群决策问题, 首先提出了基于方案属性值的相离度与模糊熵的专家权重的确定方法.然后通过线性加权得到不同专家的动态组合权重值,并将其与布尔值结合,提出了一种新的基于梯形模糊数混合多属性群决策方法.最后通过实际案例,验证了此方法的合理性与可行性.

关键词: 梯形模糊数, 相离度, 模糊熵, 动态组合权重, 布尔值, 群决策

Abstract: In order to solve the problem of group decision-making where the expert evaluation information is mixed with multiple attributes and the weights are unknown, a method for determining the weights of expert attributes based on the dissociation of attribute values and fuzzy entropy of each scheme is proposed firstly, and then the dynamic combination weights of different experts are obtained through linear weighting, and a new multi-attribute group decision-making method based on trapezoidal fuzzy number is proposed after combining them with Boolean values. Finally, the rationality and feasibility of this method are verifed by the actual case analysis.

Key words: trapezoidal fuzzy number, separation degree, fuzzy entropy, dynamic combination weight, Boolean values, group decision-making
