Why ReneWind needs failure prediction, what each prediction outcome costs, and how the solution is sequenced.

Business context

ReneWind builds and maintains wind turbine generators. A generator that fails in the field forces an unplanned replacement — the most expensive outcome in the entire maintenance chain.

Sensors across the gearbox, tower, blades and brake systems already stream data, plus environmental factors such as temperature, humidity and wind speed. That data is ciphered for confidentiality and arrives as 40 anonymous predictors, V1–V40, with a binary failure Target.

Objective
Build and tune classification models that identify generators about to fail, so they can be repaired before they break — converting expensive replacements into cheaper scheduled repairs and reducing overall maintenance cost.
Cost of each prediction outcome
True positive
Failure predicted
Repair
False negative
Failure missed
Replacement (highest)
False positive
False alarm
Inspection (lowest)
True negative
Healthy unit
No cost

Because replacement >> repair > inspection, the model must minimise false negatives first.
