Fault diagnosis in multi-component systems

Abstract

Some embodiments relate to a computer-implemented method of addressing faults in a system comprising at least one controller is described. The method comprises receiving fault information from one controller for one or more faults. The fault information comprises at least an identification of the device showing the fault and a time period during which the fault occurs. From this fault information, a plurality of fault baskets is established, wherein each fault basket for a fault comprises that fault and at least other faults in the system active at the time the fault occurs. The plurality of fault baskets is mined to identify one or more fault rules and associated fault baskets. It is then determined whether each fault rule meets a significance threshold, and if so, a corrective or preventative action for such fault rules is determined.

Dependencies are inferred from the claim text.
