A warehouse control system (WCS) directs “real-time” activities within warehouses and distribution centers. They act as a traffic regulator for warehousing activities, with the mission of running material handling systems (and in some instances, the activities of workers). A good WCS system provides a broad, yet consistent interface for material handling systems like conveyors, carousels, palletizers, sorters, etc. On the other hand, a warehouse management system (WMS) is more focused on broader activities, people, and processes, such as shipments and orders. WMS usually doesn’t reach downstream into the automated equipment itself. A WMS is more about controlling human interactions to fulfill or receive product.
