Fulfillment-hub outage
Central Hub is unavailable; active inventory and throughput must move to North and South.
Disruption control / deterministic replay
DevShift Relay operational digital twin
A decision surface for tracing disrupted inventory, directed transport capacity, order risk, and the operational cost of recovery.
Static operational view
Network readiness snapshot
Three fulfillment hubs route four product families through west and east transfer points into four demand regions.
Enable JavaScript to inspect the live WebGL twin, generate constrained plans, preview cloned state, and commit a recovery.
Included incident drills
Directed lane closure
The West Transfer → Northwest lane is closed while alternate directed paths remain available.
Demand spike + shortage
Southeast vision-kit demand rises as available hub inventory is deliberately constrained.
Seeded sandbox
A repeatable seed chooses a lane, product, and demand region for deterministic replay.
