Sortation recovers from a jammed diverter
The environment
A sorter routes cartons into outbound lanes against a warehouse control system (WCS) that was commissioned with a fixed divert map. The WCS assumes the map never changes; the floor assumes the opposite.
What went wrong
Mid-wave, a divert actuator on lane A faulted and a carton wedged. The lane photo-eye went blocked and stayed blocked. With no rule for a physical jam at this position, the WCS had exactly one response available: hold the upstream induct and page a supervisor.
Stop the induct. Halt all downstream lanes. Wait for a human to clear the jam and acknowledge. Every carton behind the blockage sits until the operator arrives — typically a multi-minute stall that cascades across the wave.
How the loop reasoned
CognitioFlow subscribed to the divert and photo-eye tags over the existing controls network. It recognized the blocked lane as a bounded, local fault rather than a line-wide one, weighed the routing goal against the downstream lane capacity, and issued a re-route to lane B — all while leaving the faulted divert flagged for inspection and notifying the operator in parallel.
Flow continued around the fault. The jam was cleared without a full stop, the exception was logged against the divert's history, and the recovery path was folded into the model so the same signature is recognized faster next time.
