共识满意度驱动的异质群体共识度测算方法

A consensus measure method for heterogeneous group driven by consensus satisfaction degree

研究群体共识决策过程的共识测度问题.从共识协调者的角度定义异质群体的共识满意度指标,用以表征共识协调者对群体关于一对方案评价值达成共识的乐观估计程度;建立一种新的OWA算子权重确定模型,构建共识满意度驱动算子对专家的偏好相似度进行集结;提出一种计算异质群体共识测度的方法.最后,通过一个算例说明方法的应用步骤与可行性.

A consensus measure problem is studied in the process of consensus decision making. From the perspective of a consensus coordinator, the optimistic level of reaching a consensus in the group about preferences over paired comparisons of the objectives can be characterized by a consensus satisfaction degree index of heterogeneous group. An OWA operator based on consensus satisfaction degree, whose weights are established by a novel determining weight model, is presented to aggregate the preference similarities of experts. A consensus degree calculation method for heterogeneous group is developed. Finally, a numerical case is used to illustrate the above operations, which can demonstrate the feasibility and validity of the proposed method.
