同理我们可以求出在第二层指标状态下，的各个比较判断矩阵的一致性指标。由

Similarly we can find the index in the state of the second layer, the consistency index of the respective judgment matrix. Because of this problem we just took a factor at several indicators, resulting in heavy weights we solved for the vector 1, may result in large errors subjective factors. B4-Ci with respect to the matrix, the matrix of second order sub-matrix is ​​determined, there will be a large error,

In the same reason, we can find the consistency index of each comparison and judging matrix in the state of the second-layer indicator. Because of this problem we take only one influencing factor under the condition of several indicators, resulting in the weight ingress to 1, which may cause a large subjective factor error. Compared to the B4-Ci matrix, the subjudgment matrix is a second-order matrix, and there will be large mistakes.

In the same way, we can find the consistency index of each comparison judgment matrix in the second level index state. Because we only take one influencing factor under the condition of several indexes, the weight vector we solve is 1, which may lead to a larger subjective factor error. Compared with the B4 CI matrix, the secondary judgment matrix is a second-order matrix, and there will be big mistakes,<br>
