基于灰色聚类的大规模群体语言评价信息集结研究

研究群体规模较大的情况下基于语言评价信息的决策方法,提出了基于灰色关联聚类的方法以降低大规模群体的协调困难;根据决策者所属群体类别差异,基于语言信息转化函数提出了类内评价指标权重确定方法,并测算了各群体类别的综合偏好;研究群体类间权重确定模型,建立了基于群体类别意见偏差最小的群体偏好集结模型;进而提出了决策者判断一致度定义以及决策者偏差协调方法.算例分析表明了该方法的应用步骤及可行性.

Group aggregation method on large-scale linguistic evaluation information based on grey cluster

The aggregation method for a large-scale group decision making problem is studied.Firstly,the grey cluster method is used to reduce the negotiation difficulty of a group.Based on the transformation formula of a linguistic evaluation,the method on the weight of criteria inside of the group is developed according to the difference of the group.Then the integration preference of each category is measured.A method of the weight of category is proposed and the group preference aggregation model is established based on the smallest deviation object among the categories.The consensus degree of decision maker is defined.Furthermore,the coordination method is proposed to achieve the coherent result of the group.The example analysis shows the steps and the feasibility of the proposed method.
