Abstract: Disclosed are methods and systems for continuously determining remaining useful lives (RULs) of vehicle components during operation of these vehicles. A method involves obtaining reference sensor data as well as operational sensor data (both of which are multidimensional) and constructing distributions of these respective data sets. The operational sensor data is obtained from a plurality of sensors, operationally coupled to a vehicle component and continuously obtaining real-time characteristics of this component. The reference sensor data is obtained, in some examples, from a database for equivalent components, long before the end of life or required replacements. Sliced-Wasserstein distances are computed between these distributions and early notification signals (ENS) are determined on these distances. Finally, a RUL of the vehicle component is determined based on the ENS using a RUL model.

Abstract: A device includes a transceiver, a processor, a network interface, and a display interface. The transceiver is configured to receive health data from an aircraft. The processor is configured to determine whether the health data indicates a maintenance condition. The network interface is configured to send a first query to a maintenance database and to receive a first response to the first query indicating a list of parts associated with the maintenance condition. The network interface is also configured to send a second query to a historical maintenance database based on the list of parts and to receive a second response to the second query indicating failure rates of the parts. The display interface is configured to provide a graphical user interface (GUI) to a display. The processor is configured to generate the GUI indicating the list of parts ordered based on the failure rates.
