基于区间对偶犹豫模糊不确定语言变量的多属性决策方法

Multi-Attribute Decision Making Method Based on Interval Values Dual Hesitant Fuzzy Uncertain Linguistic Variables

给出了区间对偶犹豫模糊不确定语言集的定义及其运算法则,构造了其得分函数、精确函数,提出了基于该语言集的加权几何算子和有序加权几何算子。同时给出了一种基于区间值对偶犹豫模糊不确定语言变量的多属性决策方法。最后通过实例验证了该方法的有效性和可行性。

The interval values dual hesitant fuzzy uncertain linguis score function and accuracy function are defined. Some aggregation tic set, its operational law, the operators are proposed, such as weighted geometric averaging operator and ordered weighted geometric averaging operator. And a method based on interval values dual hesitant fuzzy uncertain linguistic variables is proposed. Finally, an example is given to prove the validity and feasibility of the method.
