Two effective measures of intuitionistic fuzzy entropy

Based on the concept of fuzzy entropy, two effective measures of intuitionistic fuzzy entropy are proposed in intuitionistic fuzzy information, and then the essential properties of these measures are introduced. These measures are a generalized version of the fuzzy entropy and a complementarity of existing entropy for intuitionistic fuzzy sets. Based on this generalization, a connection between the concepts of the fuzzy entropy and the intuitionistic fuzzy entropy is established. Finally, a numeral example is given to show that the information measures of the proposed intuitionistic fuzzy entropy are reasonable and effective by the comparison of the proposed entropy and existing entropy.
