在层次分析法建模中，随机一致性指标用于检验矩阵的一致性，但一般参考书中只给出n=1-9或n=1-11的随机一致性指标。本文将讨论如何求取n为任意数的随机一致性指标。-In the analytic hierarchy process modeling, the random consistency index is used to test the consistency of the matrix, n = 1-9 or n = 1-11 random consistency index is given only general reference books. This article will discuss how to strike a random consistency index n is any number.
