The document discusses several management systems used in supply chain and logistics operations: 1. A Distribution Management System (DMS) monitors and controls the distribution network to reduce outages, improve operational efficiency, and increase customer satisfaction. 2. An Order Management System (OMS) automates order processing and provides inventory, vendor, customer, and financial information to improve order fulfillment. 3. A Warehouse Management System (WMS) controls product movement and storage in a warehouse to efficiently process shipping, receiving, storage, and order picking. 4. A Transportation Management System (TMS) facilitates order fulfillment by optimizing routes, loads, carriers, and transportation planning between warehouses and customers.
