运用三角模糊数的概念，根据个体加权向量，提出衡量个体间一致性的相似度量函数，由此构造个体、群体的一致性指标．在此基础上，给出群体一致性的定义，并运用个体指标提出由个体加权向量寻求群体加权向量的两种方法．最后，给出该寻求方法的算法与算例 By using the concept of triangular fuzzy numbers and according to individual weight vectors, a similarity measure function is proposed to measure the consistency between individuals, thus constructing the consistency index of individuals and groups. On this basis, the definition of group consistency is given, and two methods of finding the group weight vectors from individual weight vectors are proposed by using individual indexes. Finally, the algorithm and example of this seeking method are given
