Identification of significant sequences of fault codes by statistical hypothesis testing

摘要

In some aspects of the present application, a method for identifying significant events related to machine problems. The method includes receiving one or more machine problems; determining one or more machine problem classifications based on the one or more machine problems; generating a probability distribution that the one or more machines problems are related to the one more machine problem classifications; determining if one or more events are associated with the one or more machine problems during a predetermined time interval; and determining if the one or more events are significantly related to the one or more machine problem classifications using a statistical algorithm.
