Patent ID: 8713377

Claim:
A system to assess a serviceability of a machine having a field replaceable unit (FRU), the system comprising: a controller having a processor in communication to execute computer readable program instructions stored in a non-transitory medium, the program instructions representative of the steps of: tracking the performance parameter of the machine over time; calculating a performance index representative of a comparison of the measure of the performance parameter relative to a first predetermined threshold; generating a plurality of requests for service of the FRU of the machine based on the performance index, the plurality of requests for service not including replacement of the FRU; detecting completion of a plurality of events to service the FRU of the machine in response to the plurality of requests for service; calculating an asset healability index representative of a trend in the performance index over time between each of the events to service the FRU of the machine; and generating a request for replacement of the FRU of the machine instead of another request to service the FRU on the machine based on a comparison of the asset healability index relative to a second predetermined threshold.
