PREDICTIVE MAINTENANCE USING MACHINE LEARNING AND EXISTING DATA SOURCES

Includes supplementary materialThe United States Marine Corps must address material-readiness challenges with emerging technologies at minimum cost. Predictive maintenance using machine learning is a growing field that can be applied using free or commercial-off-the-shelf software. Naval aviation organizations already maintain a network of data repositories that collect and store current and historical data on repairable flight-critical components. Many components fail before their expected structural life as published their manufacturers, which results in costly unscheduled maintenance. The ability to predict component failures and plan for their replacement or repair can significantly increase operational readiness. This thesis develops and analyzes machine-learning models to predict the conditional probability of failure of various MV-22B flight-critical components using data from existing Naval aviation repositories. Data preprocessing, model training, and predictions use commercial-off-the-shelf software. This work can help improve material readiness and acclimatize military-aviation personnel to emerging technologies in decision making.Captain, United States Marine CorpsApproved for public release.
