Decision-making approach by employing grey incidence analysis and group negotiation

For the problems of the consistency ranking of the group decision-making scheme, from the view of group negotiation and system coordination, the grey incidence analysis and Nash bargaining model are used to establish a consistency group decision-making method. First, the concepts of the consensus partial decision-making program and the consensus overall ideal decision-making program are defined, and then a multi-object optimization model is constructed based on the satisfaction maximization of group negotiation and deviation minimization of system coordination to determine the consensus partial decision-making program and the consensus overall ideal decision-making program. Moreover, the grey incidence analysis is exploited to measure the close degrees between them. Finally, a real case of the online product evaluation verifies the validity and rationality of the proposed model.
