IMPROVEMENT OF ANALYTIC HIERARCHY PROCESS BASED ON THE REFINEMENT OF THE PROCEDURES FOR THE FORMATION OF PAIRWISE COMPARISON MATRICES

摘要

The paper provides a general description of the analytic hierarchy process and approaches to its improvement. It shows that premise for successful use of the analytic hierarchy process is an availability of the pairwise comparison matrices obtained according to the expert survey results, which are consistent and adequately reflect expert judgment. Modern approaches do not provide such a requirement in full. Therefore, the following process improvements are proposed: a two-step expert survey procedure based on the use of formalized cards to be filled by experts, and mathematical dependencies that bring the uncoordinated pairwise comparison matrices to consistency. The possibility of practical use of the proposed approach to obtain consistent pairwise comparison matrices is illustrated by a numerical example. In general, the improvements proposed increase the substantiation of decisions that are made based on the obtained results by using the analytic hierarchy process.
