MODELING OF SUSTAINABLE FUNCTIONING OF PRODUCTION AND SALES SYSTEMS ON THE BASIS OF LOGISTICS-ORIENTED APPROACH

With the use of logistics-oriented design, the industrial enterprise is considered as an integral typical production and sales system, for which it is possible to create a statistical database, which allows to analyze the transformation of flows in similar systems, and the designer can draw conclusions about the empirical laws of this transformation get a formalized operator. The industrial enterprise is considered as a production and marketing system, which consists of three basic functional subsystems — logistics, production and sales. Logistic-oriented design of such a system implies optimal organization and effective management of material flows, which helps to solve problems of systems analysis and synthesis within this approach, taking into account the requirements of an integrated approach to the organization of flows, as well as its consideration from source to final points of consumption. The methodological basis for ensuring high system-wide efficiency of formation of technical systems is formed. The ultimate goal of logistics-oriented design is to obtain a fully formalized view of the production and marketing system as part of the logic of flows and operators of their transformations, which tracked the impact of changes in any factor on system-wide economic efficiency. In generalized form, the production and marketing system is presented as follows: ensuring the necessary profitability of the system, ensuring organizational and economic stability of the system, optimizing the level of service to consumers of the system. Logistics-oriented design has key stages. The research begins with the formation of the simplest model, then the system is designed based on the analysis of motion and transformation in the system of flows. Based on this, a formalized model of the system is built and a system of constraints for the values of flow parameters and operators is formed. Based on them, the impact of changes in individual parameters on the final results of the system as a whole is estimated by modeling scenarios of the situation in the external environment. The last stage implements the feedback function to assess the feasibility of building a system based on the developed project.
