犹豫模糊语言群决策的共识性模型

针对犹豫模糊语言群决策问题,研究其共识性调整方法.首先,定义犹豫模糊语言术语集的距离测度;然后,基于该距离测度定义犹豫模糊决策矩阵间的共识性水平及其相关概念,建立共识性调整模型,该模型采用反馈机制,并且尽可能提供给专家较多的信息,以方便专家进行信息修正,达到群体共识;最后,通过具体实例说明了所提出的共识性方法的可行性和实用性.

Consensus model for hesitant fuzzy linguistic group decision making

This paper studies a the consensus approach for the decision making problems with hesitant fuzzy linguistic decision matrices. The distance measure is proposed for the hesitant fuzzy linguistic term sets. Based on the distance among the individual decision matrices,the group consensus level and some other consensus levels are defined for the hesitant fuzzy decision matrices,and the consensus research process is introduced. A consensus model is established, it defines a feedback mechanism to make the information provided for the experts as much as possible, and is helpful for the experts to adjust information and reach group consensus. Finally, a numerical example is used to illustrate the feasibility and practicability of the proposed consensus model.
