A fault list reduction approach for efficient bridge fault diagnosis

Abstract

A new fault list reduction approach is proposed for use in the first stage of a two-stage bridge fault diagnosis procedure. Modified structural analysis and layout extraction procedures are performed to obtain a reduced realistic bridge fault list that can be used in the second stage, which employs diagnostic fault simulation. The fault list reduction approach can reduce the final candidate bridge fault list by 92% to 99% compared with the diagnosis results achieved by the diagnostic fault simulator alone.
