The Sensor Failure Model

Client: FreshLine Cold StorageCold chain logistics · Grimsby

FreshLine Cold Storage, Grimsby docks · Urgent, focused

FreshLine keeps fish and vaccines cold for half of Grimsby. Its sensors fail without warning, and a room can warm for an hour before anyone notices. Megan wants a model that spots failing sensors early. Ten years of readings exist, in four vendors' formats, one of which is beeps.

Team goal · 1,500 gems

Everyone on this contract works toward one sign-off from FreshLine Cold Storage. Sign-off means the model watches every room and FreshLine puts its whole sensor fleet in our hands.
