Figure BDA0002995960890000142
The smaller the CI value is, the better the consistency of the matrix is, and when the CI is 0, the judgment that the matrix has complete consistency is performed; when CR is less than 0.1, the consistency of the matrix is good; otherwise, the judgment matrix needs to be adjusted repeatedly until CR is less than 0.1.
To further check the consistency of the matrix, we introduced the concept of random consistency. And calculating and comparing the CI with the average random consistency index RI to obtain a random consistency check index. It should be noted here that the matrices below 2 th order have good consistency and do not need to calculate random consistency indexes. The values of RI are shown in Table 5.

according to the result of the ranking of the hierarchical list, the weight value of the index of the hierarchy to a certain index of the previous hierarchy can be obtained through calculation. The total sorting needs to be performed layer by layer from bottom to top. When the highest level is calculated, the single ordering of the levels is the total ordering of the levels.
If all indexes A of a certain index level1,A2,L,AnThe total ordering has been completed, resulting in a weight vector of W ═ W1,w2,L,wn}T. And AiThe index of the hierarchy corresponding to i ═ 1,2, L, n is Ai1,Ai2,L,AinThe weight vector of the hierarchy is Wi＝{w1,w2,L,wn}T。
The overall ordering of the hierarchy also requires a consistency check. The total sorting consistency check formula is

CI is a consistency index of the total ordering of the hierarchy, CIiAnd RIiAre respectively AiAnd the corresponding consistency index and the random consistency index obtained by the hierarchical single sorting calculation are obtained, and RI is the random consistency index. CR is a random consistency indicator of the overall ranking.
