Entropy of intuitionistic fuzzy sets and its general forms

In this paper,the entropy of intuitionistic fuzzy sets is regarded as a comprehensive measure of the fuzziness and indeterminacy based on a comprehensive analysis of various kinds of current axiomatic definitions of entropy of intuitionistic fuzzy sets,and it should be consistent with the entropy of fuzzy sets when the intuitionistic fuzzy sets degenerate into the fuzzy sets.Based on this idea,a new axiomatic definition of the entropy of intuitionistic fuzzy sets is given,and several structural forms of the entropy of intuitionistic fuzzy sets are given.
