An Improved Consistency Adjustment Method of Judgment Matrix for AHP
Aiming at the poor consistency of original judgment matrix in analytic hierarchy process,the existing matrix consistency adjustment methods are analyzed.Considering the different causes of errors leading to poor consistency in the judgment matrix,based on the consistency adjustment method with geometric average,a matrix consistency adjustment method based on error identification is proposed.The improved adjustment method is simulated for different matrix orders and different accidental errors.Simulation results show that the method can effectively identify the expert accidental error and quickly adjust the judgment matrix to meet the requirements of consistency ratio.
