本文是基于互补判断矩阵的群体思维收敛性定量分析,证明当专家数足够多的时候,加权算术平均综合判断矩阵与加权几何平均综合判断矩阵都依概率收敛到客观判断矩阵,从而解释和验证了群体思维具有收敛性。 This paper is based on the quantitative analysis of the group thinking convergence of the complementary judgment matrix, and proves that when the number of experts is enough, the weighted average arithmetic comprehensive judgment matrix and the weighted geometric mean judgment matrix converge to the objective judgment matrix according to probability, so as to explain and verify Group thinking has convergence.
