摘要: 针对属性值为直觉模糊数的多属性决策问题,提出了一种新的Spearman秩相关系数的决策方法。将AHP与熵权法得到的属性权重运用博弈论均衡思想构建优化模型,并运用混合罚函数来求解最优组合权重。依据灰色关联分析思想计算各属性的关联度,将得到的各方案关联度与最优权重按自身大小进行标号,分别作为秩比较序列与秩标准序列带入Spearman秩相关系数计算中,将得到Spearman秩相关系数的大小用于优序排列。最后实例验证了该方法的有效性。

关键词: 直觉模糊数, 组合赋权, 混合罚函数, 关联度, Spearman秩相关系数

Abstract: A new decision method of Spearman rank correlation coefficient was proposed for multi-attribute decision making with intuitionistic fuzzy numbers. The attribute weights obtained by AHP and entropy weight method were used to construct the optimization model with the idea of game theory equilibrium, and the mixed penalty function was used to solve the optimal combination weights. The association degree of each attribute was calculated according to the idea of grey correlation analysis. The correlation degree and the optimal weight of each scheme were labeled according to their own size, which were taken into Spearman rank correlation coefficient calculation as comparison sequence and reference sequence respectively. The size of correlation coefficient obtained was used for priority arrangement. Finally, an example was given to verify the effectiveness of the method.

Key words: intuitionistic fuzzy number, combination empowerment, Mult-SUMT, correlation degree, Spearman rank correlation coefficient
