An Approach to Multi-Attribute Group Decision Making Based on Choquet Integral and Fuzzy TOPSIS

Two methods Choquet integral and TOPSIS are combined and applied to solve multi-attribute group decision making problems. Also, a new formulas based Hamming and Euclidean distances will be proposed to determine the distance between IFNs. In CI the inter-dependent or interactive characteristics between criteria are considered. Moreover, the output of CI of intuitionistic fuzzy numbers, is still an intuitionistic fuzzy number. Then, we can compute their distances from subjective alternatives positiveideal solution and negative ideal solution, by proposed distances formula, easily. The applicability of these methods are illustrated by numerical example.
