基于改进DEMATEL的区间对偶犹豫模糊多属性决策方法

Interval-valued Dual Hesitant Fuzzy Multi-attribute Decision Making Method based on Improved DEMATEL

针对区间对偶犹豫模糊多属性决策问题,将传统DEMATEL分析法加以改进,引入决策偏好系数,提出了一种基于中心度、原因度参量的属性权重确定方法。为避免行为偏好对距离刻画带来的主观性影响,定义了广义区间对偶犹豫模糊距离。借助加权平均(WA)算子,将权重向量与初始决策矩阵集结,得到最终的综合决策矩阵,并通过TOPSIS法对各方案进行综合评价。通过实例说明本方法的有效性和可行性。

To solve the problem of interval dual hesitant fuzzy multi-attribute decision making,the improved DEMATEL analysis method and the decision preference coefficient are introduced,and a method based on the central degree and the cause parameter for determining the weight vector is proposed in this paper.The generalized distance measure is defined to avoid the influence of behavioral preference.The final comprehensive decision matrix is obtained through assembling the weight vector and the initial decision matrix,and the programs are comprehensively evaluated by TOPSIS method.Finally,a numerical example is illustrated to prove the effectiveness and feasibility of the proposed method.
