Abstract: Aiming at the problem of fuzzy multi-attribute large group decision making,a model based on Humming distance was proposed to construct the experts'weight optimization model.Interval-valued intuitionistic fuzzy matrix was used to express the information of experts evaluation and MATLAB was used to optimize the weights of experts.The comprehensive decision making matrix was integrated by Interval-valued Intuitionistic Fuzzy Weighted Average (IIFWA) operator based on experts weight,and the weights of criteria were calculated based on information entropy theory.The VIKOR framework was employed to establish the decision process.The divergence between interval-valued intuitionistic fuzzy numbers was calculated by interval-valued intuitionistic fuzzy balance cross-entropy.A real-world case was constructed to elaborate the feasibility and effectiveness of the proposed methodology.

Key words: large group decision-making, weights of experts, balance cross-entropy, VIKOR framework
