基于区间直觉判断矩阵的群决策及逆判方法
Group decision and adverse judgment approach based on interval-valued intuitionistic judgment matrices
Abstract
文章对区间直觉判断矩阵进行研究,定义了区间直觉判断矩阵及其距离测度与相似性测度新概念,详细研究它们的性质.基于区间直觉平均算子等集成工具,建立了一种基于区间直觉模糊集模型的群决策途径,并根据群决策结果逆判评判专家的水平.最后通过具体实例证明该方法的有效性. Interval-valued intuitionistic judgment matrices are investigated in this paper.Interva-valued intuitionistic judgment matrix and its distance measure,similarity measure are defined.Some of their desirable properties are investigated in detail.Based on the interval-valued intuitionistic fuzzy sets model,an approach to group decision making is proposed by using intuitionistic average operator and the experts' level is judged adversely by the results of the group decision.Finally,a practical example is provided to verify the effectiveness of the proposed approach.
