A New Method for Consistency Correction of Judgment Matrix in AHP
H. Zhang, Y. Wei, G. Yu
In order to continue to study the consistency correction of the judgment matrix, we studied the relationship between the inconsistency of the judgment matrix and the perturbation matrix,
proposed the concept of the perturbation deviation matrix. Then two new methods for the consistency correction of the judgment matrix are presented based on the convex combination of perturbation deviation matrix. Finally, the new methods were validated by examples and compared with the traditional AHP method.
