ABSTRACT

For the task of managing contracts in the supply chain in terms of choosing the optimal contract model, the article for the first time presents the optimization procedures at many criteria. The paper shows that such a format of the model allows to consider pure risks that can be formalized as private individual criteria. In this case, they can be taken into account in a special format for presenting estimates of particular criteria. As such a format, the article discusses a method of presenting them corresponding to a generalized selection criteria. For this approach, the article presents optimization procedures for choosing the type of contract based on traditional selection methods. The article illustrates that this approach may lead to different solutions for the alternatives that expands the tools for adapting optimization procedures to the preferences of the decision maker. For the first time the paper proves that according to the format of the selection criterion for the geometric mean (and the same for the multiplication criterion), the transition to the format of generalized data does not change the best choice and ranking of alternatives. The appropriate modeling results are presented within the framework of the pure risk concept.

ABSTRACT

 Consideration of the supply chain from the point of view of objective understanding as a set of individuals and legal entities, interacting specifically and precisely in material, financial and information flows, presupposes the availability of a tool for fixing the rules for interaction of such parties. Such a tool already exists, it is a contract / agreement / agreement of the parties. It is the contract model of the supply chain that is of great importance in the process of value formation of the product, as it can be considered as a legal documental basis for mutual arrangements for the supply chain. Contract management tasks in the supply chain in terms of the optimal contract model choice are formalized it the paper for the first time as decision-making tasks under many criteria. This format of models allows to consider risks that can be formalized in the form of separate individual criteria. It is shown that a dimensionality phenomenon is associated with problems of this type which can be eliminated on the basis of a transition to new formats for the presentation of estimates of particular criteria: 1) the format of generalized selection criteria; 2) to the standardized form of the problem of choice. For both approaches, tasks of multicriteria choice of the contract model are formalized.
