针对属性值为三参数区间灰数的多属性决策问题, 提出了一种基 于改进~TOPSIS 的三参数区间灰数多属性决策方法. 文章根据三参数区间灰 数的取值特征, 定了三参数区间灰数相容度的概念; 其次分析了经典~TOPSIS 方法的不足, 结合三参数区间灰数的相容度, 定义了方案的加权相对相容度, 依据加权相容度对方案进行排序; 最后将可变熵拓展到决策信息为三参数区间灰数的情况, 建立了确定属性权重的可变熵优化模型, 并通过实例验证了该方法的有效性和合理性.
WANG XiaAiming at multi-attribute decision making problems, in which the attribute value of alternatives is three-parameter interval grey number, a multi-attri- bute decision making method based on improved TOPSIS is proposed. In this paper, according to the value characteristics of three parameter interval grey number, the concept of compatibility degree of three parameter interval grey number is defined. Secondly, the shortcomings of the classical TOPSIS method are analyzed. Combined with the compatibility degree of three parameter interval grey number, the weighted relative compatibility degree of the scheme is defined, and the scheme is sorted according to the weighted compatibility degree. Finally, the variable entropy is extended to the case that the decision information is three-parameter interval grey number, and a variable entropy optimization model is established to determine the attribute weight. The validity and rationality of the method are verified by an example.
