不同偏好形式判断矩阵的二元语义群决策方法

Group decision making method based on two-tuple linguistic for judgment matrices with different fuzzy preferences

利用三角(区间)模糊数与二元语义之间的转化方法,研究了三角(区间)模糊数互补判断矩阵与基于二元语义的语言判断矩阵之间的内在联系,论证了该转化方法的有效性.同时给出了一种群体判断矩阵信息为不同模糊偏好形式的集结方法,最后,通过算例表明了该方法是有效的.

Using the transformations between triangular （interval） fuzzy number and two-tuple linguistic, this paper studies the relationship between triangular （interval） fuzzy number complementary judgment matrix and linguistic judgment matrix based on two-tuple linguistic, in which the effectiveness of the transformations is demonstrated. At the same time, an aggregative method is put forward, in which group judgment information takes the form of different fuzzy preferences. Finally, it is illustrated by a numerical example that the proposed method is effective.
