The consistency check coefficient CR is calculated as:
Figure BDA0003315189590000071
and when CR is less than 0.1, the first judgment matrix is considered to pass the consistency check, otherwise, the first judgment matrix is considered to not pass the consistency check, the importance ratio scores of the primary evaluation indexes are required to be obtained again, and then the consistency check is carried out.
