Abstract:

Intuitionistic Fuzzy Sets (IFS) are the further promotion of fuzzy sets,which are more flexible and practical than the traditional Fuzzy sets in dealing with vagueness and uncertainty.However,existing similarity measurement methods cannot realize the axiomatization of the similarity,or they may incur some counterintuitive instances.Based on the similarity measurement of intuitionistic fuzzy sets proposed by Boran and Akay,we propose a novel measurement formula.Example analysis demonstrates the rationality and effectiveness of the proposed formula.
