Abstract:
A method for processing repair data and fault data comprising a plurality of faults from one or more machines, said method for facilitating analysis of a malfunctioning machine comprising:(a) selecting from the fault data those faults having significant statistical relevance further comprising; (a)(1) selecting at least one time window; (a)(2) determining a threshold; (a)(3) determining the number of occurrences of a fault during the time window; (a)(4) determining the relationship between the number of occurrences of the fault and the threshold; and (a)(5) in response to step (a4), determining the faults having significant statistical relevance; (b) selecting a repair from the repair data; (c) generating a case using the selected repair from step (b) and the selected faults from step (a); (d) generating for each of the cases at least one repair and distinct fault cluster combination; and (e) assigning a weight to each of the repair and distinct fault cluster combinations whereby the weight facilitates prediction of at least one repair for the malfunctioning machine.
