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
