Warehouse control system

What is a warehouse control system?

A warehouse control system (WCS) is a software application that manages and coordinates automated machines.

It acts as the bridge between the warehouse management system (WMS) and physical equipment such as:

The WCS translates high-level fulfillment instructions into specific equipment commands. It functions as a warehouse execution system, optimizing routing, managing traffic flow, preventing collisions and monitoring equipment status.

WCS vs WMS: key differences

WCS and WMS cover different stages of warehouse logistics:

  • WMS operates at the strategy level: it decides which items to pick, which locations to use and how to route orders through the facility

  • WCS operates at the execution level: it manages equipment in real time, controlling conveyor speeds, sortation systems and autonomous mobile robots (AMRs)

Integration between WCS and WMS enables coordinated automated operations. The WMS sends fulfillment tasks to the WCS and the WCS executes them, reporting completion back to the WMS.

How WCS streamlines warehouse operations

Conveyor control

The WCS adjusts conveyor speeds based on downstream capacity, activates diverters to route items efficiently and balances item flow to prevent bottlenecks.

Sortation systems

The WCS uses scanners to read package identifiers and determine sort destinations. It automatically triggers diverters and pusher mechanisms, routing items to assigned lanes or zones.

Material handling

The WCS coordinates crane movements, shelf retrieval sequences and robot traffic. Through material handling control, it maximizes storage density and retrieval speed while preventing equipment conflicts.

Equipment maintenance

The WCS monitors equipment health and predicts maintenance needs, alerting operators to issues before failures occur.
