一致性检验可以反映专家或决策者思维的一致性水平，是基于判断矩阵确定专家

Consistency test can reflect the consistency level of experts or decision makers' thinking, and is an important factor in determining the weight of experts based on the judgment matrix [20]. Saaty introduced the random consistency index RI to measure the level of consistency [19]. The RI value is the average value obtained by Saaty's random simulation test on a large number of paired comparison matrices, and it is also the random consistency index of the judgment matrix [21], as shown in Table 2. The consistency ratio is shown in equation (4).
