Some Comments on the Analytic Hierarchy Process

Abstract

Some comments are made on the analytic hierarchy process of Thomas L. Saaty, which has gained widespread acceptance as a valuable tool for multicriteria decision-making. Saaty's validation of the method against physical laws is criticized, a multiplicative scale is suggested for making judgements, and the problem of rank reversal is discussed with reference to two published papers.
