Multi-Factor Variable Weight Comprehensive Decision-Making Method Based on Intuitionistic Fuzzy Number
Taking intuitionistic fuzzy number as a point in polar coordinate system,a new representation of intuitionistic fuzzy number is given.Then,a new measure of intuitionistic fuzzy number is defined,that is energy function value.A new ranking method of intuitionistic fuzzy numbers is proposed by using the values of energy functions.Furthermore,the state variable weight vector of intuitionistic fuzzy number is constructed by means of real state variable weight vector and energy function vector.Subsequently,the variable weight formula is given in which the factor weights are real numbers but the values of factors are intuitionistic fuzzy numbers.At the same time,the intuitionistic fuzzy comprehensive decision model with variable weight is established.Finally,an application example is given to verify the scientificity and practicality of the proposed method.
