Outline of Final Research Achievements |
Theoretical results have been obtained to establish a theory for reliable decentralized failure diagnosis of networked discrete event systems. It may be possible that some local diagnosis decisions are not available, due to some reasons including breakdown of local diagnosers and disconnection of the network. Motivated by this, an algorithm is developed for verifying whether the system is diagnosable even if some of the diagnosis decisions are not available. In addition, an algorithm is presented for computing the maximum detection delay of a failure in such a case. As related work, theoretical results on failure diagnosis subject to sensor failures and supervisory control have also been obtained.
