SINGLE-ECHELON INVENTORY SYSTEM
A Single-Echelon Inventory System is one wherein a single Distribution Center (DC) acts as a central repository between the supplier of the inventory and the customer-facing outlets. In a Single-Echelon Network, an individual material-location combination is not affected by any other material or location.
MULTI-ECHELON INVENTORY SYSTEM
A Multi-Echelon Inventory System is one that relies heavily on layers of suppliers distributed across multiple distribution centers and that is based on outsourced manufacturing. In such a system, new inventory shipments are first stored at a Central or Regional Distribution Center (RDC).
