Intuitionistic Trapezoidal Fuzzy Multi-attribute Decision Making Method Based on Grey Relational Analysis

Sha Fu, Zhongli Liu, Hangjun Zhou, Dan Song and Bo Li    

Abstract: The study proposed a multiple attribute decision making method based on grey relational analysis, for the multiple attribute decision making problems with the evaluation information given in the form of intuition trapezoidal fuzzy numbers. First, give the definition of intuitionistic fuzzy numbers and distance formula and then obtained the grey relational coefficient about intuition trapezoidal fuzzy numbers based on grey relational analysis, to calculate the relational grade of each options by using relational coefficient and sort all the options by the size of this value in order to get the best option. Finally, it verified the feasibility and effectiveness of the proposed method through a numerical example.
