犹豫模糊多属性决策的折中比值法

Compromise ratio method for hesitant fuzzy multi-attribute decision making

针对属性值为犹豫模糊元的多属性决策问题,提出了一种新的多属性决策方法——折中比值法。折中比值法方法是通过定义能同时反映出备选方案尽可能地接近正理想点又同时尽可能地远离负理想点,并且把决策者的主观态度也包含在内的排序指标对备选方案进行排序和择优。最后,通过应用实例说明了所提出的方法的有效性和可行性。

For the multiple attribute decision making problem with attribute value expressed as hesitant fuzzy elements, a new multi-attribute decision making method, and named compromise ratio method is proposed. Compromise ratio method is developed by introducing the ranking index based on the concept that the chosen alternative should be as aloes as possible to the ideal solution and as far away from the negative ideal solution as possible simultaneously, while the decision maker's subjective attitude are also included. Finally, a practical example is presented to demonstrate the effectiveness and feasibility of the proposed method.
