基于对偶犹豫模糊语言变量的多属性决策方法

首先定义了对偶犹豫模糊语言变量,然后给出其运算规则、得分值函数、精确值函数、比较规则以及对偶犹豫模糊语言变量的加权算术平均算子、有序加权算术平均算子和混合平均算子。针对属性值为对偶犹豫模糊语言变量的多属性决策问题,提出了一种基于对偶犹豫模糊语言变量集结算子的多属性决策方法。最后,结合国家电网公司合作单位选择问题,验证了该方法的有效性和可行性。

Multi-attribute Decision-making Method Based on DualHesitant Fuzzy Linguistic Variables

In this paper, the dual hesitant fuzzy linguistic variable is defined at first, then some basic definitions such as operational laws, score function, accuracy function, comparison rules are proposed. Next, dual hesitant fuzzy linguistic weighted arithmetic averaging operator, dual hesitant fuzzy linguistic ordered weighted arithmetic averaging operator and dual hesitant fuzzy linguistic hybrid averaging operator are presented, and some properties are discussed. For fuzzy multi-attribute decision making problems in which the attribute values take the form of dual hesitant fuzzy linguistic variables, a method based on dual hesitant fuzzy linguistic aggregation operators is proposed. Finally, a practical partner selection problem of the State Grid Corporation of China is given to verify the effectiveness and feasibility of the developed method.
