Abstract:

Methods of intuitionistic fuzzy entropy are analyzed. Considering the classical mathematic concepts of strict greaterthan and strict lessthan, a concept strict intuitionistic fuzzy entropy (SIFE) and an axiomatic definition are proposed by solving defect that entropy of the degree of membership function equals the degree of nonemembership function but different intuitionistic indexes cannot be distinguished. A technique for constructing the SIFE based on this definition is proposed and an expression is abstracted. The SIFE is more adaptive in decision and sorting. The validity is certified by the example and the limit is overcomed by comparing to other methods.
