[Abstract]
Intuitionistic fuzzy sets are more flexible and practical than traditional fuzzy sets in dealing with vagueness, hesitant vagueness and other uncertainty aspects, they are further promotion of the fuzzy sets. The similarity ,a tool of describing similarity degree of two (intuitive) fuzzy sets, has an important application in intuitionistic fuzzy multi-attribute decision making. However, we find that in some cases the reflected similarity and the actual similarity are inconsistent by analyzing similarity method adopted by the existing literature, therefore, in this paper, a new kind of similarity calculation formula is presented, the TOPSIS method based on intuitionistic fuzzy similarity is proposed and it is applied to multiple attribute decision making problems, Finally, an example is given to illustrate the rationality and validity.
