THE APPROACH TO ASSESSING THE STABILITY OF SOLUTIONS OBTAINED
BY MULTI-CRITERIA METHODS TO THE ERRORS OF THE VALUES
OF THE IMPORTANCE COEFFICIENTS OF THE INDICATORS
Abstract. The authors show that the solutions obtained by multi-criteria methods (ranking of alternatives and formation of their core) can be affected by errors of the values of the importance ratio of the indicators that characterize the system under study. The stability analysis of such solutions is shown to be an important component of the conclusions about the possibility of practical use of the recommendations developed on their basis. The stability analysis approach is proposed and used in several examples of calculations. This approach will increase the substantiation of the results of the solution of multi-criteria problems due to obtaining a sufficiently objective basis for the conclusion on their stability.
Keywords: multi-criteria method, importance ratio, error of importance ratio value, ranking of alternatives, solution stability, alternatives core.
