Qualitative Multi-faults Diagnosis based on Automated Planning - I: Theory and Modelling
Résumé
This paper is intended to present a flexible qualitative framework of multi-faults diagnosis based on the first principles theory of Reiter (1987). We extend his consistency-based approach to deal with the dynamic and continuous systems and offer a necessary assumption and a formal demonstration. Multi-faults diagnosis is a partially observable problem because there is usually not enough information about faults. STRIPS, a classic technique of automated planning, is chosen to build the system model. It provides the reasoning ability for the multi-faults diagnosis when diagnosis is formalized as reasoning from effects to causes with causal knowledge.
