Opinion consensus game model based on adjustment preference in social network

Social network, Adjustment preference game, Interaction mechanism, Group consensus, Risk preference

In group decision making(GDM), the game of decision makers as an interaction mechanism is introduced in a consensus reaching process. Decision makers conduct the game to exchange opinions and adjust their opinions. Remarkably, in the adjustment process, the adjustment behaviors of decision makers depend on the decision makers' preference. The decision makers can transform preference type based on game. In this case, we propose an optimization model based on the decision makers' preference game to promote group consensus. Specifically, based on the idea of three-way decision, we combine the risk preference and consensus situation of decision maker to identify the preference type of decision maker and match minimum adjustment model and maximum return model for different preference types of decision makers. Then, on the basis of the trust relationship of social network, this paper establishes the game rules of decision makers' preference type transformation. Further, we devise hybrid adjustment model to promote the group consensus according to the discussion above. Finally, an experimental analysis is used to verify the effectiveness and properties of the proposed method.
