摘要

本文研究了直觉模糊偏好关系下群体决策的一致性和一致性问题。为了检验ifpr的一致性和专家的共识，分别引入了新的一致性指数和共识指数。通过最小化初始ifpr和相应改进ifpr的偏差，构建了一个目标程序，以同时提高ifpr的一致性和群体共识。最后，提出了一种新的基于ifpr的群体决策算法。最后以供应商选择为例说明了该方法的应用。

A consistency and consensus based method for group decision making with intuitionistic fuzzy preference relations

This paper addresses the consistency and consensus of group decision making with intuitionistic fuzzy preference relations (IFPRs). To check the consistency of IFPRs and the consensus among experts, a new consistency index and a consensus index are introduced, respectively. By minimizing deviations of initial IFPRs and corresponding improved IFPRs, a goal program is built to improve the consistency of IFPRs and group consensus simultaneously. Finally, a novel algorithm is proposed for group decision making with IFPRs. An example of a supplier selection is provided to show the application of the proposed method.
