Definition.
Vendor managed inventory (VMI) is a means of optimizing supply chain performance in which the manufacturer is responsible for maintaining the distributor's inventory levels. The manufacturer has access to the distributor's inventory data and is responsible for generating purchase orders. Under VMI the manufacturer receives electronic data (usually EDI or via the internet) that tells him the distributors sales and stock levels. The manufacturer can view every item that the distributor carriers as well as true point of sale data. The manufacturer is responsible for creating and maintaining the inventory plan. Under VMI, the manufacturer generates the order, not the distributor. (Williams, 1996).
Consignment inventory (CI) is when the supplier places inventory at a customer's location and retains ownership of the inventory. Payment is not made until the item is actually sold. In other words, the supplier places some of his inventory in his customer's possession (in their store or warehouse) and allows them to sell or consume directly from his stock. The customer purchases the inventory only after he has resold or consumed it (Williams, 1996).
