Distributed Diagnosis by using a Condensed Local Representation of the Global Diagnoses with Minimal Cardinality
The set of diagnoses is commonly calculated in consistency based diagnosis,
where a diagnosis includes a set of faulty components. In some applications,
the search for diagnoses is reduced to the set of diagnoses with minimal
cardinality. In distributed systems, local diagnoses are calculated in each
agent, and global diagnoses are calculated for the complete system. The key
contribution in the present paper is an algorithm that synchronizes the local
diagnoses in each agent such that these represent the global diagnoses with
minimal cardinality. The resulting diagnoses only include faulty components
used by the specific agent, and are therefore a condensed local representation of
the global diagnoses with minimal cardinality.
