Abstract:
1. A method for identifying significant events related to machine problems, the method comprising: receiving one or more machine problems and associated one or more fault codes; determining one or more machine problem classifications based on the one or more machine problems and the associated one or more fault codes that were received; generating a log of the one or more machine problems, the associated one or more fault codes, and the one or more machine problem classifications that were determined from a plurality of users for a predetermined time interval; generating a baseline probability distribution comprising the one or more machines problems with respect to the one or more machine problem classifications; for each fault code that was received, calculating a secondary probability distribution comprising a number of times that each of the associated fault codes occurred for the one or more machine problems classifications that were determined; determining that two or more fault codes in the log are significantly related to the one or more machine problems using a Chi-squared distribution test to compare the baseline probability distribution against each of the second probability distributions; and diagnosing the machine problems using the one or more fault codes that were determined to be significantly related.
