针对阶段权重未知且偏好信息表示为区间模糊数的多阶段大群体应急决策问题,提出一种新的群决策方法。首先给出了区间模糊数相似度公式,利用该公式对各阶段的专家偏好信息进行聚类;然后构建相对熵优化模型对聚集权重和阶段权重进行求解,得到整个决策过程的综合群体偏好,根据综合群体偏好对备选方案进行排序,确定最佳方案;最后通过算例对该方法的有效性和可行性进行验证。
針對階段權重未知且偏好信息錶示為區間模糊數的多階段大群體應急決策問題,提齣一種新的群決策方法。首先給齣瞭區間模糊數相似度公式,利用該公式對各階段的專傢偏好信息進行聚類;然後構建相對熵優化模型對聚集權重和階段權重進行求解,得到整箇決策過程的綜閤群體偏好,根據綜閤群體偏好對備選方案進行排序,確定最佳方案;最後通過算例對該方法的有效性和可行性進行驗證。

For the multi-period large group emergency decision-making problem that stage weights are unknown and preference information is interval fuzzy number(IFNs), a new group decision-making method is proposed. Firstly,the similarity formula between INs is given, and each stage preference information is clustered by this for-mula.Then,the trelative entropy method is used to determine cluster weights and stage weights.The alternatives ranking result is obtained based on the comprehensive group preference, and the best alterative is selected.Fi-nally, an example shows the effectiveness and practicability of this method.
