The problem

Unpredictable equipment failures were driving downtime that hit both production output and maintenance cost. The objective was to forecast failures rather than react to them.

What was built

A predictive maintenance system that forecasts issues, interprets technician feedback in natural language, and returns step-by-step repair instructions in real time.

Technical approach

Data collection
Machinery manuals digitised into JSON for metadata indexing.
Retrieval-augmented generation
BM25 retrieval over the manual corpus, generating repair instructions on demand.
Natural language understanding
BERT and RoBERTa models interpret what the technician typed and route to the right procedure.

Measurement framework

Deployment evidence is drawn from the published engagement. The delivery and measurement plans are case-specific recommendations grounded in the documented solution and results.

Evidence status
The published case study documents an operational predictive-maintenance system combining equipment telemetry, failure prediction and grounded repair guidance.
Indicative delivery plan
Connect historical and live equipment data, validate failure thresholds, pilot alerts with the maintenance team, then expand to the approved asset population.
Recommended baseline
Recommended: the 90-day pre-deployment average for unplanned downtime hours, maintenance labour per work order and maintenance-related operating cost, normalised by equipment operating hours.
Recommended measurement method
Compare matched equipment over equal operating-hour windows before and after deployment. Exclude planned shutdowns, reconcile events with CMMS and production logs, and report monthly with the same asset population.

Recommended items are not presented as the original study method. They should be replaced with the confirmed project methodology when the underlying records are approved for publication.
