The increasing complexity of supply chains and the dynamic development of information technology result in the increased interest of the Multi-Echelon - Inventory - Management concept. Although the concept is well - known in the last decade worldwide, in Poland the concept is still not enough explored. This paper presents the supply chain from the perspective of Multi-Echelon - Inventory - Management concept realization. The basis for the concept is to optimize the inventory level in the entire supply chain, what is considerably more difficult than managing it in a single-echelon. The main contribution of this paper is to introduce main challenges of multilevel systems and determine the classification of risks and sources of uncertainty in the entire supply chain.
