在这篇论文,我们调查决定制造者给的决定信息拿间隔的形式的组决策问题模糊偏爱关系。我们首先给一个索引测量二间隔的类似度模糊偏爱关系,并且利用类似索引检查组意见的一致性度。而且,我们使用错误繁殖原则决定聚集的矩阵的优先级向量,然后开发一条途径基于间隔组织决策模糊偏爱关系。最后,我们给一个例子说明发达途径。
In this paper, we investigate group decision making problems where the decision information given by decision makers takes the form of interval fuzzy preference relations. We first give an index to measure the similarity degree of two interval fuzzy preference relations, and utilize the similarity index to check the consistency degree of group opinion. Furthermore, we use the error-propagation principle to determine the priority vector of the aggregated matrix, and then develop an approach to group decision making based on interval fuzzy preference relations. Finally, we give an example to illustrate the developed approach.
