What role does the WES take relative to the WMS in optimizing robot efficiency?

It acts as the real-time scheduler, dynamically overriding or optimizing tasks dictated by the WMS.

The Warehouse Execution System (WES) is identified as the crucial software layer responsible for immediate, moment-to-moment control and optimization within a modern logistics environment. While the Warehouse Management System (WMS) maintains the broader, long-term business logic and overall planning framework for inventory, the WES steps in to manage execution in real-time. This means that if the WMS dictates a sequence of tasks, the WES dynamically adjusts those instructions based on current conditions such as robot location, battery status, traffic, and immediate task priority. This ability to dynamically override or fine-tune the WMS directives is highlighted as a significant structural software invention, providing the necessary flexibility for integrating diverse and continuously evolving hardware solutions on the warehouse floor.
