【摘要】 运用三角模糊数的概念提出两种有限方案的群体评价方法：１）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，并给出群体一致性的定义，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；２）利用三角模糊数构造语言评价集，并给出一种基于语言的方案评价方法与算法。更多还原

【Abstract】 In this paper, we present two assessment methods unedr the concept of triangular fuzzy number: (1) A similarity measuring function is proposed to measure the similarity between individual preference and construct individual and group indexes. Based on these work, this paper presents a definition of group consensus and provids two methods of searching the group preference from individual prefrences. (2) A linguistic assessment set and method are constructed by triangular fuzzy number.更多还原
