A Warehouse Control System (WCS) is operational software that connects various automated systems like conveyors, sorters, Automated Storage and Retrieval systems (AS/RS) and Pick/Put to Light. The WCS communicates data to the controllers, typically Programmable Logic Controllers (PLCs), and triggers its operation to support material flow through the distribution center’s warehouse(s).

A Warehouse Execution System (WES) is built around performance optimization software that sits between the client’s Warehouse Management System (WMS) and includes all the functionality of a WCS. However, the WES uses sophisticated algorithms to leverage real-time inputs from all “islands of automation” including order finishing, manifesting and other sources, as well as data from inventory, order, labor, transportation and other activities. A WES will optimize a distribution center’s activity and dynamically manage it throughout all processes.

A WES includes a variety of options that are easily configured during installation. This allows users to utilize only the functionality they need and implement new functionality when it becomes necessary for growth or to accommodate changes in material flow. The ideal WES integrates all commercially available WMS brands from any provider and includes built-in control capability to interface with any semi or fully automated material handling systems.
