Abstract
A major breakthrough in multi-criteria decision analysis has been the Analytic Hierarchy Process (AHP), with its innovative applications of matrix theory and pioneering concept of consistency in human judgments for pairwise comparisons. However, the criterion for assessing consistency among these judgments in a pairwise comparison matrix of AHP is somewhat cumbersome to apply and the available procedures for improving the consistency of the matrix focus mainly on the effects rather than the source of the inconsistency: the underlying human judgments. This paper presents a simplified criterion for assessing the consistency of a pairwise comparison matrix. It further develops a systematic procedure for modifying an insufficiently consistent matrix to total consistency based on the degree of confidence the decision-maker places on these judgments, and discusses the implications of this total consistency modification procedure.
