Comments on “Fuzzy multicriteria decision making method based on the improved accuracy function for interval-valued intuitionistic fuzzy sets” by Ridvan Sahin

In the above paper, the author proposed an improved accuracy function, and then by using the function, a multicriteria fuzzy decision-making method is established. However, the application example given in the above cited reference is inappropriate to show the accuracy function’s advantages. In this short letter, we redefine a set of data; the practicality and effectiveness of the proposed approach are demonstrated with the use of the presented data.
