A critical analysis of the eigenvalue method used to derive priorities in AHP

摘要

A lot of research has been devoted to the critical analysis of the Analytic Hierarchy Process (AHP), from various perspectives. However, as far as we know, no one has addressed a fundamental problem, discussed in this paper, concerning the meaning of the priority vector derived from the principal eigenvalue method used in AHP. The role of AHP's consistency ratio is also analysed. (C) 2006 Elsevier B.V. All rights reserved.
