在群体决策（GDM）过程中，在选择最佳备选方案之前，专家之间最好达成高度的共识或协议。由于大多数决策问题的复杂性，个人的偏好可能不满足形式属性。一致性就是其中之一，它与传递性有关，显然，在进行理性决策时，一致的信息，即不包含任何矛盾的信息，比包含某些矛盾的信息更合适。因此，在一个GDM过程中，一致性也应该寻求after.In本文中，我们提出了一个共识模型的GDM问题，收益从一致性的共识。该模型包括一个新的一致性达到模块的一致性措施的基础上。特别是，该模型生成专家应如何改变他们的偏好，以达到高一致性和共识度的解决方案的建议。
In group decision making (GDM) processes, prior to the selection of the best alternative(s), it would be desirable that experts achieve a high degree of consensus or agreement between them. Due to the complexity of most decision making problems, individuals’ preferences may not satisfy formal properties. Consistency is one of such properties, and it is associated with thetransitivity property.Obviously, when carrying out a rational decision making, consistent information, i.e. information which does not imply any kind of contradiction, is more appropriate than information containing some contradictions. Therefore, in a GDM process, consistency should also be sought after.In this paper we present a consensus model for GDM problems that proceeds from consistency to consensus. This model includes a novel consistency reaching module based on consistency measures. In particular, the model generates advice on how experts should change their preferences in order to reach a solution with high consistency and consensus degrees.
