The reconciliation mechanism by cooperative intention index for managing non-cooperative behaviors in social network group decision making

Social network group consensus is a hybrid cooperative and non-cooperative problem, with the management of non-cooperative behavior as a key topic. In response, this study investigates the reconciliation mechanism to manage non-cooperative behaviors based on a cooperative intention index (CII). First, a CII index driven by preference similarity and trust relationships is constructed, which predicts the compromise domain of decision makers (DMs). Subsequently, this study recognizes three types of non-cooperative behaviors from the group and individual proposal perspectives in turn: (i)Type-1 cooperation with the group; (ii)Type-2 non-cooperation with the group but cooperation with the individual; and (iii)Type-3 non-cooperation with both the group and the individual. Then, reconciliation mechanisms applicable to different types of mediation are proposed. Then, group-orientated, individual-orientated and compulsory reconciliation mechanisms are proposed for different types. Finally, a demonstration example and discussions are provided to illustrate the efficacy of the proposed model.
