摘要
考虑到区间值模糊集中代表元在决策分析中的重要作用,提出三参数区间值模糊集和三参数区间值模糊值的概念,给出了三参数区间值模糊值之间的运算关系,定义了三参数区间值模糊值之间一种新的距离.基于这种距离,针对三参数区间值模糊集上的一个多属性决策模型,提出了一种TOPSIS决策方法.最后以实例说明该方法的有效性.
Considering the important role of representation element in an interval-valued fuzzy set for decision analysis, the concepts of three parameters interval-valued fuzzy set and three parameters interval- valued fuzzy value are proposed, some operators on three parameters interval-valued fuzzy values are given and a new distance between three parameters interval-valued fuzzy values is defined. Based on the proposed distance, a TOPSIS decision-making method is shown for a multi-criteria decision making model on three parameters interval-valued fuzzy sets. Finally, a practical example is provided to illustrate the method＇s effectiveness.
