Comparison of Decision-Making Methods Comparison of Decision-Making Methods

Abstract


A comparison is made between the most commonly used decision-making method (AHP),
and two methods developed by the authors (APM and CSM). It is shown that the newly
developed methods do not change the correlations and types of inequalities between the
global priorities of the alternatives when the number of alternatives changes. This
differentiates them from the AHP, which does change them. Also, unlike the AHP, which
uses pair comparison matrices of criteria relative to goals and alternatives, the developed
methods use the creation of pair-comparison matrices of criteria relative to alternatives and of
alternatives relative to criteria. In order to obtain a result, it is enough to perform an expert
analysis of all the alternatives and one criteria, or otherwise of all the criteria and one
alternative. The other pair-comparison matrices are obtained either from the conditions of
inverse symmetric matrices, or from the proportionality of weight correlations. The results of
the developed methods fully coincide.
