Abstract: Large group decision making is a difficult problem because it is hard to coordinate the conflict among multiple people. Conflict measure problems of large group are studied with every decision preferences expressed by interval-valued intuitionistic trapezoidal fuzzy number (IITFN). Firstly, the distance measurement between two IITFNs is given and conflict function among group members is proposed. Then, large group members are clustered. Afterwards, the cluster and group conflict measure models are proposed respectively and applied in the aggregating of large group preferences. Finally, a simulation example validates the model. This model deals with the analysis and coordination of large group decision, so it is applicable for group decision support system.

Key words: interval-valued intuitionistic trapezoidal fuzzy number, large group decision, conflict measure
