Формализация предпочтений для повышения качества решений при многокритериальном выборе
The article presents the format of formalizing and clarifying the decision-maker preferences, which is designed to improve the quality of multi-criteria selection of the best decisions based on synthesis of analytic hierarchy process and traditional methods of multicriteria optimization. This synthesis involves a two-step transition to modified values of the partial criteria indicators. This allows manager to take into account the attitude of the decision-maker to the initial values of these indicators, as well as the relation to the importance of partial criteria themselves. After the modification indicators of partial criteria, the optimization procedure can be continued on the basis of any traditional selection criteria. Also the approach gives the possibility of verifying the pessimistic position of decision-maker preferences by setting individual level of pessimism in each particular criteria. New visualization of pairwise comparisons structure is proposed in the form of a graph that allows manager to simplify the setting of decision-maker’s preferences and enhance the quality of decision-making in many criteria.
