A FMECA Backed Generalized Fault Diagnosis Expert System

Rule based expert systems are widely used in online fault diagnosis systems, while failure mode, effects and criticality analysis (FMECA) is a widely used information intensive method to gather failure modes and its related information. We utilize FMECA worksheet as a backbone to authorize generalized rule base against device types, and present how to commission this generalized rule base to an operable device specific rule base through an example. At the end, a diagnosis rule base related software UIs are presented.
