Self-confidence as one of the human psychological behaviors has important influence on emergency management decision making, which has been ignored in existing methods. To fill this gap, we dedicate to design a group decision making approach considering self-confidence behaviors and apply it to the environmental pollution emergency management. In the proposed method, the self-confident fuzzy preference relations are utilized to express experts' evaluations. This new type of preference relations allow experts to express multiple self-confidence levels when providing their evaluations, which can deal with the self-confidence of them well. To apply the proposed group decision making method to environmental pollution emergency management, a novel determination of the decision weights of experts is given combining the subjective and objective weights. The subjective weight can be directly assigned by organizer, while the objective weight is determined by the self-confidence degree of experts on their evaluations. Afterwards, by utilizing the weighted averaging operator, the individuals' evaluations can be aggregated into a collective one. To do that, some operational laws for self-confident fuzzy preference relations are introduced. And then, a self-confidence score function is designed to get the best solution for environmental pollution emergency management. Finally, some analyses and discussions show that the proposed method is feasible and effective.
自信作为人类心理行为之一,对突发事件管理决策有重要影响,但现有方法往往忽略了这一点。为了填补这一空白,我们致力于设计一种考虑自信行为的群体决策方法,并将其应用于环境污染突发事件管理。在提出的方法中,利用自信模糊偏好关系来表示专家的评价。这种新型偏好关系允许专家在提供评价时表达多种自信水平,从而能够很好地处理他们的自信程度。为了将所提出的群体决策方法应用于环境污染突发事件管理,结合主观权重和客观权重,给出了一种新的专家决策权重的确定方法。主观权重可以由组织者直接分配,而客观权重则由专家对其评价的自信程度决定。然后,利用加权平均算子,将个体的评价汇总为一个整体。为此,引入了自信模糊偏好关系的一些运算规律。然后,设计了一个自信得分函数,以获得环境污染突发事件管理的最佳解决方案。最后,通过一些分析和讨论表明,所提出的方法是可行和有效的。
