The paper proposes an approach to the improvement of the method of successive concessions, which is widely used in solving multicriteria optimization problems in logistics. For the first time, the special formats (hard and flexible) are formalized for the use of this method, making it possible to improve the quality of decision-making procedures by many criteria. These formats are illustrated by the example of the problem of the best choice of a location and the form of ownership of a warehouse. For the first time, the paper discusses the possibility of specifying analytically the ordering of particular criteria, needed for the method of successive concessions, if it is required by the decision-maker. For the first time, practical situations are analyzed, when for some groups of particular criteria such an analytical approach to setting the order of optimization procedures will determine the same importance between them. For such situations, an approach to the analysis of various variants of ordering of particular criteria is presented in order to expand the scope of available applications for the use of the method of successive concessions. For the first time, managers are given the opportunity to rank the given alternatives according to the method of successive concessions. The influence of various variants of ordering particular criteria on the ranking of alternatives is analyzed by such an optimization method.

In this paper a new format of the procedures for determining the best solution is presented to solve multicriteria optimization problems in the supply chain. This format includes: 1) modifying parameters of the particular criteria, taking into account the attitude of decision maker (DM) to such indicators and the importance of the attitude of DM to criteria themselves (which is implemented using a comparison procedures developed for the analytic hierarchy process); 2) implementation of procedures for the selection on the basis of the traditional theory of selection criteria (which corresponds to the synthesis procedures, analytical hierarchy process method with the traditional theory of optimization procedures). Illustrations of the proposed approach to the modification of the selection procedures are given for the problem related to optimizing the locations of the warehouse and its form of ownership. It is shown that the presented approach to optimization solutions will expand the available arsenal of methods for selecting managers that will give an opportunity to improve the quality of decisions due to better adapt them to the preferences of the decision maker.
