Model‐based diagnosis for open systems fault management

Abstract

The information model chosen by the ISO for the management of open systems is object‐oriented. We provide an effective mapping from the structural and behavioural specification of the managed objects of open systems to a compact logical form suitable for model‐based diagnosis. Based thereon, we present an efficient algorithm that localizes faults by repairing logical models invalidated through system observations and show that it computes all minimal diagnoses.
