Abstract
In the context of globalization of markets and increasing competition, supply chain management is becoming critical to ensuring the sustainability and efficiency of business. The relevance of this study is due to the need to develop new management models that can adapt to rapidly changing market conditions and customer needs. The purpose of the study is to develop and practically implement an open supply chain management model based on the planning mechanisms and modern optimization methods. The model is aimed at integrating various functional areas, such as demand, inventory, supply and production planning management, with an emphasis on increasing transparency and efficiency. The study used data analysis methods, including ARIMA models for demand forecasting, multi-criteria analysis (AHP) for supplier selection and linear programming for production planning optimization. Microservice architecture was also used to integrate all functional areas into a single supply chain management system. The novelty of the study lies in proposing an integrated model of open supply chain management that takes into account modern technologies and optimization methods, as well as in applying an integrated approach to managing logistics processes. The significance of the study is demonstrated by its practical applicability for companies engaged in the production and distribution of goods, which allows them to effectively adapt to changes in the market, minimize risks and increase customer satisfaction. The results of the study can be used for further developments in the field of supply chain management and business process optimization.
