Incorporating interaction and transaction behaviors into a bi-level consensus model fusing with maximum return and minimum cost

Abstract

In group decision making, the decision participants may exhibit various interaction behaviors, some of them are efficient at facilitating the efficiency of consensus reaching process. Motivated by the view of this, a bi-level consensus model with maximum return and minimum cost considering interaction and transaction behaviors (MRMC-IT) is proposed in the way of adopting the Choquet integral. The bi-level feedback mechanism based on the adjustment of opinions guarantees the interaction between the moderator in the upper level and the decision makers in the lower level. Meanwhile, a transaction mechanism of discourse weights is elicited to present the trading behaviors between the pairwise decision makers. Additionally, in order to solve the complex proposal, a bi-level interactive approach based on satisfactory degree is applied to obtain a satisfactory solution for all decision participants. Finally, an application of sewage discharge rights trading is conducted to demonstrate the validity and the rationality of the proposal.
