Just-in-Sequence (JIS) Supply
Just-in-sequence is an automotive supply method in which parts are delivered to the assembly line not only just in time but in the exact order of the vehicles being built, so each part matches its vehicle.
When a vehicle body reaches a defined trigger point, typically around paint exit or trim line entry, the manufacturer's system sends a sequence call-off to the supplier. The supplier builds or picks the variant-specific parts, such as seats, cockpit modules, bumpers, door panels or wheel and tyre sets, loads them in vehicle order and delivers them to the line within a fixed time window, so the operator takes the next part for the next vehicle.
JIS handles the high variant complexity of modern vehicles without storing every variant beside the line, reducing floor space, inventory and picking errors. It is used mainly for bulky, high-variant modules, often supplied from facilities close to the assembly plant.
JIS depends on a stable build sequence and reliable data exchange, usually through electronic data interchange between the manufacturer and suppliers. Re-sequencing caused by paint repairs or line disruptions must be managed, for example with buffers that restore the planned order. Because a missing or wrong part can stop the line, suppliers and manufacturers plan contingency stock, verification scans and escalation procedures.
Key points
- Parts arrive in the exact build order of the vehicles
- Sequence call-offs are triggered at a point such as paint exit
- Used for bulky, high-variant modules such as seats and cockpits
- Needs a stable sequence, reliable data exchange and contingencies
Where AiVibe comes in
AiAmbA use cases include visual inspection on textile and automotive lines, predictive maintenance and digital twins. Existing lines are retrofitted with edge devices, and AI agents only propose changes for a trained operator to confirm.
