Method of identifying abnormal behavior in a fleet of vehicles

摘要

A method is disclosed for monitoring a complex system, such as a fleet of aircraft, having multiple sub-systems described by a plurality of operating parameters. Data pertaining to the operating parameters is continually generated during operation of the vehicles. The data is normalized to take into account variability factor and stored in a central database. New incoming data from the sub-systems is continually compared with the stored data to identify abnormalities. The invention is applicable to the monitoring of a fleet of aircraft.
