Abstract

Method and system for analyzing fault log data to predict the time until a machine-disabling failure occurs is provided. The method allows for searching (210) in a database of historical fault log data from a plurality of machines for the occurrence of respective fault patterns indicative of incipient failures of a respective machine subsystem.
The method further allows for searching (210) in a database including historical failures for the respective machine subsystem. The method also allows for computing elapsed time (246) between respective occurrences of the fault patterns and the occurrence of the subsystem failures.
