The challenge

Semantic middleware that reads plain-language shift-floor logs and turns them into validated constraints — across six different scheduling and logistics problem types

Segment: Cross-domain disruption response

Operational disruptions get reported in plain language — a maintenance note, a delayed-crew email, a staff member calling in unavailable — while the schedule lives in a separate mathematical model nobody updates in real time. Someone has to read the note, judge what it actually means for the plan, and manually re-enter it as a constraint, and that translation step is where response time is lost. A language model can read the note in seconds, but taken alone it can also misread an ambiguous one — inventing a resource that doesn't exist or a duration that isn't there — which is exactly the failure mode a validation-conscious operations team can't tolerate.

The approach

How the deployment was structured

The same note, four different problem types

A machine fault, a traffic delay, an unavailable inspector, and a staff absence all start as the same kind of plain-language note — and each gets parsed into the constraint format its own scheduling model actually needs, whether that's job shop scheduling, vehicle routing, project scheduling, or workforce rostering.

Checked against a knowledge graph before it counts

Every extracted constraint is validated against a symbolic knowledge graph before it can reach the solver — in offline validation, this caught 88.2% of the incorrect or hallucinated extractions a language model produced on its own.

Repair, re-optimize, or ask a person

An adaptive policy chooses between a fast local repair, a full re-optimization, or escalation to human review, based on how confident the extraction is and how much slack the schedule has left.

Validated across six NP-hard domains

The same semantic-to-symbolic pipeline was tested across job shop scheduling, vehicle routing, project scheduling, nurse rostering, bin packing, and network flow — not tuned to one industry's vocabulary.

What changed

The gain shows up in the automotive validation study this was tested against: cutting decision latency from 15 minutes to 2 by removing the manual note-to-constraint translation step — the same pipeline that, without retuning, extracted correct constraints across five other scheduling domains.
