Abstract:
A method for identifying a plurality of critical faults in a fleet of machines, the method comprising:a) collecting from a predetermined plurality of the fleet of machines respective fleet machine data indicative of each fault logged over a predetermined period of time;b) determining the relative ranking of the faults logged in the collected fleet machine data by:i) identifying in the collected fleet machine data respective faults most frequently occurring relative to one another;ii) identifying in the most frequently occurring faults, respective faults that, relative to one another, affect a higher number of machines;c) classifying the faults identified in step b) based on an expected level of machine degradation associated with the identified faults; andd) storing any faults classified as likely to result in an inmminent machine mission failure in a predetermined database of critical faults.
