Abstract: We analyzed material supply chains and managerial decision-making under uncertainty in medium and large-sized Russian companies. We demonstrated the need to optimize and stabilize logistics operations amid import substitution policies and international restrictions. We showed that properly designed supply chains reduce material consumption and labor costs. We outlined five principal types of logistics: procurement, production, distribution, warehousing, and customs, and characterized their objectives and core tasks. We found that methods for searching and optimizing logistics solutions are not universal and depend on specific variables and uncertainty factors, so companies must continuously adapt their chains to changing conditions. We emphasized the importance of developing flexible analytical tools that account for multiple factors and provide timely support for managerial decisions.

Keywords: supply chains, import substitution, optimization, logistics decomposition, decision-making under uncertainty.
