Run your next build on a twin of your line.
Factory N+1 is a digital twin of your actual assembly line, kept in sync with every real build. Try a part change, run thousands of virtual units, and see yield and failure modes before EVT or DVT.
Your line, observed
CAD, tolerances, SOPs, station video, splats, controller logs.
Modeled station by station
Physics where the laws are known, learned models where they are not.
Try revision N+1
An engineer or an agent changes a part or a process on the twin.
See the reaction
Fit, force, torque, jams: predicted yield and ranked failure modes.
Held to the real build
Each real build's results correct the twin. Its error is published.
A simulation is a snapshot. A twin is held to the world.
A simulation projects one outcome and is rarely checked again. A twin is a working model of your specific line, corrected by what that line actually produces, so the scenarios you run on it track the real world.
We twin the stations we can measure first.
Harder physics such as flex cables, adhesives, glass and cosmetics comes after we publish fidelity on these.
