Spare Parts Demand Forecasting
ML-Augmented Demand Forecaster for Spare Parts
The ML-Augmented Demand Forecaster for Spare Parts is a zero-mass software system stored on radiation-hardened NOR flash that predicts component consumption across a 12-month forecast horizon. Drawing 1 W of operational power with a 500,000-hour mean time between failures, it models time-series usage history, remaining useful life metrics, and operations forecasts to optimize inventory reorder points. Operating in the unshielded lunar radiation environment without a protective magnetosphere, the system uses authenticated updates to maintain memory integrity, supporting a 100-year operational lifetime while iteratively refining machine learning accuracy as mission data accumulates.
