摘要
针对区间二元语义多属性群决策中的专家客观赋权问题,提出了一种区间二元语义群决策的双向专家权重确定方法。首先设置专家初始权重,通过专家个体与群体决策矩阵的偏差距离计算专家的偏离权重,再通过专家的直觉模糊熵计算专家的模糊熵权重,结合偏离权重和模糊熵权重,经过多次迭代后得到稳定的专家双向权重。该权重既反映了专家偏好信息与群体偏好信息的一致性,同时也反映了专家对决策问题的了解程度。最后,实例验证了该算法的可行性与有效性。
A method of determining the bidirectional objective weight of expert based on interval two-tuple linguistic group decision making is proposed.On the basis of the subjective weight of expert,the deviation weight of expert is calculated by the dif- ferences between each individual expert decision matrix and group expert decision matrix,and fuzzy weight of expert is calculated by intuitionistie tuzzy entropy of each individual expert.In the end the stable bidirectional objective weight of expert are achieved after several iterations.The weight reflects not only the consistency between the preterenee information and the group preterenee in- formation,but also the degree of the expert＇s understanding of the decision problem.The teasibility and efffectiveness of the proposed method are approved by an instance.
