In this study; It is aimed to evaluate the financial performances of 22 banks in Turkey between the years 2009-2018 according to the α-levels of fuzzy multicriteria decision-making methods. In addition, it is aimed to determine which α-intercept level result of fuzzy multi-criteria decision-making methods comes to the fore by integrating with the Copeland method. 26 criteria were used in the application. The weights of the criteria used were calculated using the fuzzy Shannon Entropy method according to the cut-off intervals of α=0.1, α=0.3, α=0.5, α=0.7 and α=0.9. Performance analysis was made with Fuzzy Topsis and Fuzzy Vikor methods. The relationship between the methods and Copeland method rankings was evaluated by using the Spearman rank correlation test. The ranking results of the Copeland method, Fuzzy Topsis and Fuzzy Vikor methods were compared and evaluated. [ABSTRACT FROM AUTHOR]
