چکیده

It has long been known with the Analytic Hierarchy Process (AHP) that addition or deletion of a copy of an existing alternative can cause the rank of other alternatives to reverse (Belton and Gear, 1983). Recently, Finan and Hurley (2002) discovered that removing a non-discriminating criterion from a multilevel AHP hierarchy causes the same phenomenon. This makes AHP appear deficient, since such removals should have no effect upon the final rank order. It has also been known that addition or removal of alternatives not being copies of existing alternatives can cause ranks to reverse (Saaty, 2000).

The Analysis of the Principal Eigenvector of Pairwise Comparison Matrices

This paper develops the spectral properties of pairwise comparison matrices (PCM) used in the multicriteria decision making method called analytic hierarchy process (AHP). Perturbed PCMs are introduced which may result in a reversal of the rank order of the decision alternatives. The analysis utilizes matrix theory to derive the principal eigenvector components of perturbed PCMs in explicit for...

A New Approach to Understanding and Finding Remedy for Rank Reversals in the Additive Analytic Hierarchy Process

The Analytic Hierarchy Process (AHP) which was developed by Saaty (1977, 1980, 1995) has been a widely used, discussed and debated multiple criteria decision making (MCDM) technique during the last twenty five years or more. Belton and Gear (1983) showed that additive aggregation method allowed rank order of the alternatives to change when a new alternative is added or an existing one is delete...

Two New Cases of Rank Reversals when the AHP and Some of its Additive Variants are Used that do not Occur with the Multiplicative AHP

Many researchers have long observed some cases in which certain ranking irregularities can occur when the original analytic hierarchy process (AHP), or some of its variants, are used. This paper presents two new categories of ranking irregularities which defy common intuition. These ranking irregularities occur when one decomposes a decision problem into a set of smaller problems each defined o...

Measuring patients’ priorities using the Analytic Hierarchy Process in comparison with Best-Worst-Scaling and rating cards: methodological aspects and ranking tasks

BACKGROUND Identifying patient priorities and preference measurements have gained importance as patients claim a more active role in health care decision making. Due to the variety of existing methods, it is challenging to define an appropriate method for each decision problem. This study demonstrates the impact of the non-standardized Analytic Hierarchy Process (AHP) method on priorities, and ...
