【摘要】：针对风险型大群体决策问题,考虑专家权重确定的复杂性,提出基于累积前景理论的决策信息处理和考虑双层专家权重确定的大群体决策方法.采用二元语义获取并表达专家的评价信息;基于累积前景理论计算方案的综合前景价值矩阵;采用双层专家权重确定方法,第1层利用聚类方法对大群体成员价值向量进行聚类,根据聚类结果确定聚集群权重,第2层利用熵权法获得专家熵权,二者结合得到专家权重.通过确定专家权重和综合前景价值矩阵得出最终的决策结果.最后通过算例表明了所提出方法的可行性和有效性.
[Abstract]:Considering the complexity of expert weight determination, a decision information processing method based on cumulative foreground theory and a large group decision making method considering two-level expert weight determination are proposed. The evaluation information of experts is obtained and expressed by binary semantics; the comprehensive foreground value matrix is calculated based on cumulative foreground theory; and the two-level expert weight determination method is adopted. In the first layer, the value vector of large group members is clustered by clustering method, and the weight of cluster is determined according to the clustering results. In the second layer, the expert entropy weight is obtained by using entropy weight method, and the expert weight is obtained by combining the two methods. The final decision result is obtained by determining expert weight and comprehensive foreground value matrix. Finally, an example is given to show the feasibility and effectiveness of the proposed method.
