Abstract
A method for facilitating maintenance management of a propulsion system, such as an engine, for a vehicle is disclosed. The method comprises obtaining, for each of a plurality of propulsion systems, records of maintenance events experienced by the propulsion system, and records of traversals of transport routes by the propulsion system during a period of propulsion system operation. The method further comprises using a Machine Learning model to classify the recorded maintenance events into a plurality of maintenance categories. The method then comprises identifying, from the classified recorded maintenance events and the records of traversals of transport routes, a correlation between a given maintenance category and the transport routes traversed by propulsion systems during operational periods preceding maintenance events classified into the maintenance category. The correlation may be used in maintenance and/or route planning for propulsion systems.
