The Methods and Algorithm of Searching Consensus under Group Decision Making Opinions
群决策一致性寻求方法与算法

In this paper, a similarity measuring function is proposed under the concept of triangular fuzzy number. This function can be used to measure the similarity between individual preference and to construct individual and group consensus index. Based on these work, this paper presents a definition of group consensus, and in the end, provides two methods of searching group preference vector from individual preference vectors.
