公平问题已经引起了制造业、服务业和政府部门的广泛关注。在群体决策中，决策者在感到不公平时，可能会破坏共识，拒绝最终的解决方案。因此，本文的目的是提出一个共识模型，其中包括公平性的关注。本文主要研究在协商一致过程中，决策者从协调人那里获得补偿的公平性问题。社会比较理论和基尼系数被用来定义（DM）的公平度。我们提出了一个最大公平的共识模型，以有限的成本提供平衡的共识解决方案。同时，探讨了DM公平性的一些性质.此外，我们提出了一个数值分析，以验证所提出的模型的适用性。最后，通过仿真分析验证了该方案的有效性.
Fairness has attracted extensive concern in manufacturing, service sector, and government agencies. In group decision making (GDM), decision makers (DMs) may destroy the consensus and reject the final solution when they feel unfair. Therefore, the purpose of this paper is to propose a consensus model which incorporated fairness concern. The paper focus on the fairness of compensations that (DMs) get from moderator in consensus reaching process (CRP). Social comparison theory and Gini coefficient are employed to define the fairness degrees of (DMs). We propose a maximum fairness consensus model with limited cost to provide balanced consensus solution. Meanwhile, some properties of (DMs') fairness are explored. Furthermore, we present a numerical analysis to verify the applicability of the proposed model. Finally, some simulation analyses are used to explore the effectiveness of the proposal.
