基于模糊Borda法的概率语义术语集群决策方法研究
首发时间:2020-01-02
摘要:针对群决策问题中决策的复杂性,不确定性以及决策者主观偏好的模糊性,采用概率语义术语集,作为决策者犹豫和不确定的评价信息的表示。即通过为语义变量赋予不同的概率以表达不同程度偏好。由于不同决策者对同一对象集评价结果存在差异,同时为充分考虑不同意见之间的耦合性,相关性与隶属度,采用模糊Borda组合评价法对各决策者评价意见进行综合;计算综合得分并据此得到最优方案。最后以某地森林火灾应急救援方案评估为例,验证了所提方法的有效性。

Research on group decision making of probabilistic linguistic terms based on fuzzy Borda method
Abstract:Aiming at the complexity, uncertainty and ambiguity of decision-makers' subjective preferences in group decision-making problems, a set of probabilistic linguistic terms is used as a representation of evaluation information for decision-makers hesitation and uncertainty. That is, by assigning different probabilities to linguistic terms to express different degrees of preference. Because different decision makers have different evaluation results on the same object set, in order to fully consider the coupling, correlation and membership between different opinions, the fuzzy Borda combination evaluation method is used to synthesize the evaluation opinions of each decision maker; calculate the comprehensive score and based on this, the optimal solution is obtained. Finally, the evaluation of a forest fire emergency rescue plan in a certain place is taken as an example to verify the effectiveness of the proposed method.
