The article focuses on key aspects of inventory management within the context of the construction industry. It addresses issues related to the implementation of an inventory management system, particularly considering various types of risks that can impact supply chains and developing strategies to minimize them. The article emphasizes the importance of effective management of relationships with suppliers, as they play a crucial role in ensuring the stability and reliability of supplies. A comprehensive approach is proposed, which includes the development and implementation of a mathematical model for optimizing the cost parameters of material flow. The model is based on generalized nomenclature cases and allows enterprises to conduct more efficient planning and control of expenses during the stages of product movement and storage. The importance of a strategic approach to supply chain management is demonstrated, taking into account the specificity and dynamics of the construction industry. Particular attention is given to adapting the model to different market conditions and the needs of specific enterprises, which allows for achieving high flexibility and efficiency in managing material flows. The article highlights the analysis of multi-nomenclature supply, which is an important aspect for the construction industry where the need for a variety of materials and components is high. It also includes a parametric base, encompassing the analysis of storage area, restrictions on the minimum size and cost of delivered products, storage costs, potential order volumes, and the assessment of lost benefits. This analysis enables the identification of key points for optimization and implementation of changes in supply chains. The main contribution of the article lies in the development of a model that can be adapted for different types of enterprises in the construction industry. The presented model allows for effective inventory management, reducing associated costs while simultaneously increasing overall productivity and the quality of supply chain management. The article separately considers methods of analysis and forecasting of material resource needs, which are important for ensuring continuity and efficiency of construction processes. The importance of flexibility in supply chains in response to changes in demand and market conditions is highlighted, as well as the necessity of integrating modern information technologies for more effective data and process management. Specific recommendations and methodologies are proposed, which can be useful for managers involved in planning and optimizing supply chains. These recommendations include strategies for balancing between costs and efficiency, methods for risk assessment and management, and approaches for integrating new technological solutions.
