Selection procedure of the approximation methods for deriving prioritiesČančer, Vesna (Avtor) accuracyanalytic hierarchy processapproximation methodpairwise comparisonsprioritysimulationBackground:When pairwise comparisons are used to express preferences foralternatives or judgments on criteria's importance, several methods can be used to derive priorities in multi-criteria decision-making. In the case of inconsistency, different methods give different results. Objectives:The main goal of this paper is to present the procedure of measuring the accuracy of the selected approximation methods based on pairwise comparisons compared to the priorities obtained by the eigenvalue method. It also aims toillustrate the procedure onthe numerical example characterisedby acceptable inconsistency.Methods/Approach:The presented procedure is based on a prescriptive approach, the fixed ratio scale, reciprocal pairwise comparison matrices,and consistency ratio.Mean absolute deviation and mean absolute percentage deviation are used to measureaccuracy.Results:The first result is the theoretical statement of the priorities’ accuracy measurement procedure. The results of the numerical example characterisedbythe preferencesof strength slight to strong plus show that,on average, the most accurate approximation method is the geometric mean method. Conclusions:The research contributes to the literatureonprescriptive approaches to decision-making. The results can show potential users which approximation method to use and lecturers which of them to include in the curriculum portfolio.Bussiness information technology20242025-03-18 03:08:56Znanstveno delo92171UDK: 519.8COBISS_ID: 210089731DOI: 10.2478/bsrj-2024-0015ISSN pri članku: 1847-9375sl
