针对具有多部门多指标特征的复杂大群体应急决策问题,提出一种新的决策方法.首先,给出直觉模糊数相似度公式,将其作为相聚度公式对专家偏好进行聚类;然后,以同一部门指标数据的方案区分度最大化为目标,构建优化模型以确定部门指标权重;接着,基于部门信息区分度结合极大熵原理对部门权重进行求解,进而对备选方案进行排序;最后,通过一个算例验证了所提出方法的可行性和有效性.
A new decision-making method is proposed for the emergency decision-making of large and complex groups with multi-sectoral and multi-index features. Firstly, the similarity formula of intuitionistic fuzzy number is given, which is used as the clustering degree formula to cluster the experts’ preferences. Then, Then, based on the division degree of the department information and the maximum entropy principle, the department weights are solved and the alternatives are sorted. Finally, An example is given to verify the feasibility and effectiveness of the proposed method.
