The applied multi-criteria optimization problem - selecting the optimal structure of key performance indicators in the information system with heterogeneous data was considered. Preference relations are based on measurement results, probability estimates and subjective judgments. A modified analytic hierarchy process with exact calculations of the priority matrix eigenvalues was applied. Assessments of accuracy, stability and asymptotic sensitivity of the solving algorithms were given.
A mathematical model to assess the distribution of extreme eigenvalues of the pairwise comparison matrix, analyzed in the presence of errors and perturbations of the matrix elements using the analytic hierarchy process for decision-making within the multicriteria problem was developed. It was shown that the benefit from applying the new proposed methodology for accurate calculation of eigenvalues lies in ensuring the solution stability to perturbations of the values of the matrix elements and errors of intermediate calculations.
The obtained results can be used to improve the efficiency of information systems in two ways. Firstly, evaluation accuracy and detail of priorities of selected key indicators according to their relative importance are improved. Secondly, sustainability of information systems at selected and priority-arranged KPIs are critically evaluated.
