摘要
基于偏序结构、属性值是用模糊语言给出且每个属性没有决定权重的多属性群决策问题提出了一种综合权重方法。该方法运用模糊集合理论求出每对方案关于每个属性的模糊偏好关系,然后通过对决策者的冲突偏好确定综合权重来解决该问题。当综合权重不存在时,需要调整决策者们的全部或部分偏好,以达到一致意见。该方法具有概念清晰,符合现实决策问题的特点,得出的综合权重能反映各个决策者对方案的偏好。最后给出了一个算例。
Based on partial order preference of groups, multi-attribute group decision making problem without determining weights are studied and attribute values are given using linguistic term. First, the fuzzy preference relation between alternatives for each criterion is worked out, and then this problem is solved through determining compromise weight and participants with conflicting preference. We need to adjust （to reverse or to withdraw） some or all of the preference from different participants when compromise weight is not be. The method has the clear concept and feasibility. The compromise weights obtained by the method reflect all participants＇ preference. Finally, a numerical exampie is used to show the feasibility and effectiveness of the proposed method.
