Claim 19:
20. The method of claim 19, wherein the aircraft is from a plurality of aircraft of a type of aircraft, and determining the demand for the replacement aircraft part includes:
accessing, via the processing circuitry of the electronic device, a first time series of observations of first variables that describe in-service operation of the aircraft, a second time series of observations of second variables that describe maintenance of the aircraft, and a third time series of observations of third variables that describe at least one of weather or terrain in an environment of the aircraft during the in-service operation and the maintenance of the aircraft;
determining, via the processing circuitry of the electronic device, a behavior model of the type of aircraft that is trained to predict the demand for the replacement aircraft part from a training set of observations the first variables, the second variables, and the third variables across the plurality of aircraft of the type of aircraft, the behavior model implemented as a directed acyclic graph of machine learning models that are connected to one another, an output of a first of the machine learning models fed as input to a second of the machine learning models; and
applying, via the processing circuitry of the electronic device, the first time series, the second time series and the third time series to the behavior model to predict the demand for the replacement aircraft part.
