Abstract:
1. A method for processing fault log data from a machine comprising a plurality of respective pieces of equipment, the method further processing operational parameter data indicative of operational end/or environmental conditions for the respective pieces of equipment, the method comprising: collecting fault log data comprising a plurality of faults from any malfunctioning piece of equipment; collecting operational parameter data relatable to each respective time of occurrence of the plurality of faults from the malfunctioning equipment; identifying a plurality of distinct faults in the fault log data; identifying a plurality of data buckets indicative of respective levels of each operational parameter; generating at least one distinct fault cluster from the plurality of distinct faults; relating to each generated fault cluster a respective quantization of at least one operational parameter to provide at least one fault cluster configurable in at least one of the following cluster configurations: a stand-alone fault cluster configuration and a cluster configuration enhanced with quantized operational parameter data; generating a plurality of weighted repair and distinct fault cluster combinations enhanceable with quantized operational parameter data, wherein each of the plurality of weighted repair and distinct fault cluster combinations is generated from a plurality of cases, each case comprising a repair and at least one distinct fault enhanceable with quantized operational parameter data; determining a respective weight for each of the plurality of weighted repair and distinct fault cluster combinations enhanced with quantized operational parameter data, wherein said weight is determined by: counting the number of times a respective fault cluster combination with quantized operational parameter data sharing a common quantization level for at least one operational parameter occurs in cases comprising related repairs; counting the total number of times the combination with the common quantization level occurs in said plurality of cases; and computing the ratio of the counted number of times the combination occurs in cases comprising related repairs over the counted number of times the combination occurs in the plurality of cases; and identifying at least one repair for the at least one fault cluster enhanced with quantized operational parameter data using the plurality of weighted repair and distinct fault cluster combinations enhanceable with quantized operational parameter data.
