On modified AHP with the weights of criteria related to the consistency of the pairwise comparison matrix

Abstract

This paper assumes that the inconsistency of the pairwise comparison in the AHP methodology comes from the decision maker’s distortion over his preference transitivity. We propose the method to modify the weights of the criterion where the pairwise comparison among alternatives is inconsistent. Our method undervalues the criteria under which preference of the decision maker among alternatives is inconsistent, and highly evaluates the criteria where his preference is clear.
