摘要: 针对决策信息为Pythagorean模糊数,属性权重完全未知的风险型多属性决策问题,提出了一种基于Pythagorean模糊熵的考虑决策者后悔与失望规避心理行为的决策方法。首先,计算备选方案和理想点各属性的效用值,从而获得各备选方案的后悔-欣喜值、失望-愉悦值及感知效用值。其次,构建了一种Pythagorean模糊熵,并给出基于该Pythagorean模糊熵的属性权重确定方法,利用属性权重加权求和获得备选方案综合感知效用值,从而对方案进行排序。最后,通过算例说明方法的可行性和优点,并分析了后悔规避系数δ和失望规避系数τ对决策结果的影响。

Abstract: For the problem of risky multiple attribute decision making, in which the attribute values are the Pythagorean fuzzy numbers and the information about criteria weights is completely unknown, a decision making method is proposed with regret aversion and disappointment aversion based on Pythagorean fuzzy entropy. Firstly, regret-rejoice value, disappointment-elation value and perceived utility value of alternatives are obtained by the utility value of each attribute for alternatives and the ideal alternative. Secondly, a kind of technique for constructing Pythagorean fuzzy entropy is proposed, and a method is developed based on the proposed entropy values to obtain unknown attribute weight. Furthermore, overall utility values of alternatives are calculated with weighted sum method and a ranking of alternatives can be determined by using the overall utility values. Finally, a numerical example is given to verify the effectiveness and advantage of the proposed method, and the influence of different regret aversion parameters and disappointment?aversion parameters on decision making is analyzed.

Key words: multiple attribute decision making, Pythagorean fuzzy entropy, regret aversion, disappointment aversion
