1. A method comprising:

  • establishing a database of part replacement and fault occurrence history comprising device symptoms based on human generated maintenance records and device maintained data for a plurality of devices;

    creating a model based on information within said database that links sequences of faults to specific replacement parts for said plurality of devices;

    remotely predicting part need probabilities for a specific device by applying said model to faults for said specific device and to a history of said specific device, wherein said remotely predicting comprises matching a sequence of fault codes of said history of said specific device with patterns within said information within said database; and

    outputting to a user a list of potential replacement parts and corresponding part need probabilities for each potential replacement part on said list,wherein each of said part need probabilities comprises a percentage probability that a corresponding potential replacement part will be needed for said specific device.
