The AI Digital Twin top model, formula by formula.

Nothing here is a black box. The twin is a point-to-point graph solver wrapped in a material-substitution model; these are the exact quantities it returns for every API call.

1 · Point-to-point graph

Every element is a node: origin point, transform point, install point, recovery point. Edges carry mass, distance and energy. The twin solves the lowest-mass path between the design intent and a certified supply node.

2 · Baseline vs twin mass

A linear baseline mass Mb is computed from standard sections and virgin sourcing. The twin returns Mt, the mass of the optimised path after topology reduction, reuse substitution and right-sizing.

3 · Savings & multiplier

Material saving S = Mb − Mt (tonnes). The efficiency multiplier is X = Mb / Mt, which reaches up to 100x when a whole assembly is replaced by recovered stock plus a minimal connector set.

4 · Circular economy points

Points P = S × Cf × Rq × Lf. Cf is the stream carbon factor, Rq the recovery quality of the matched stock (0–1), Lf the loop factor (1.0 closed loop, 0.6 open loop, 0.3 downcycle).

The same numbers are returned by /v1/twin/optimize and metered against the stream key that authenticated the call.
