A technique for constructing intuitionistic fuzzy entropy

To the problem that intuitionistic fuzzy entropy(IFE) can not be expressed in the equilibrium state of supportability and opposability of neutral evidences indicated in the intuitionistic index,a type of technique for constructing IFE is proposed.First,based on the hypothesis of an equilibrium state,the internal relationships of three factors of interactitities among rules impacting the magnitude of IFE are revealed and the geometrical illustration is presented.Then,a set of intutionistic restrictive conditions for IFE are analyzed.An axiomatized definition of IFE is proposed and the minimum calculation property is indicated.Finally,through analyzing and comparing by a set of calculating examples,the results show the correction,reasonability and effectiveness of the proposed technique.
