Abstract
The consensus-reaching process (CRP) is an effective tool for reducing differences of opinion. In general, the costs and resources associated with the CRP are limited. Therefore, the concept of minimum-cost consensus (MCC) has been proposed and used widely in various group decision-making contexts. As an important resource for influencing decision-making, trust provides a common-sense perception that the opinion of a high-trust DM is considered to be widely recognized by others. We hold that the DM with high trust but low consensus has the right to reduce the consensus cost by voluntarily losing some trust. Consequently, an improved MCC model considering trust loss is developed. Finally, we present a numerical example to illustrate the feasibility of the proposed consensus model. A comparative analysis is conducted to explore the influence of trust loss on the CRP.
