MAINTAINING AN AIRCRAFT WITH AUTOMATED ACQUISITION OF REPLACEMENT AIRCRAFT PARTS

Abstract:

A method is provided for maintaining an aircraft of a type of aircraft. The method includes accessing time series of observations of variables that describe in-service operation of the aircraft, maintenance of the aircraft, and weather and/or terrain in an environment of the aircraft during in-service operation and maintenance. The method includes determining a behavior model that is trained to predict demand for replacement aircraft parts from a training set across a plurality of aircraft of the type of aircraft. The behavior model is implemented as a directed acyclic graph of machine learning models that are connected to one another. The time series are applied to the behavior model to predict the demand for the replacement aircraft parts, a plan is created for acquisition of the replacement aircraft parts and maintenance of the aircraft based on the demand as predicted, and the plan is executed.
