WCS stands for Warehouse Control System and is used in warehouse automation. It is a software program that controls all the warehouse operations including inventory management, order fulfilment, and shipping. WCS can be used to track inventory levels, optimize warehouse workflows, and manage customer orders. It can also be used to generate reports and analyses data to help improve warehouse operations. Additionally, WCS can integrate with other warehouse technologies such as RFID, barcode scanners, and automated pick-and-place systems.
