CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper we deal with the problem of failure diagnosis of discrete event systems with decentralized information. The decentralized architecture that we use is composed by a set of sites communicating their diagnosis information with a coordinator that is responsible of detecting the occurrence of failures in the system. In particular, first we present a protocol that defines the communication rules between the sites and the coordinator. Secondly, we prove that this protocol does not produce false alarms. Moreover, we give sufficient conditions for diagnosability based on the notion of failure ambiguous strings. Finally, we compare the protocol here presented with other two protocols that we presented in a previous work.

The decentralized architecture that we use is composed by a set of sites communicating their diagnosis information with a coordinator that is responsible of detecting the occurrence of failures in the system. In particular, first we present a protocol that defines the communication rules between the sites and the coordinator. Secondly, we prove that this protocol does not produce false alarms. Moreover, we give sufficient conditions for diagnosability based on the notion of failure ambiguous strings. Finally, we compare the protocol here presented with other two protocols that we presented in a previous work. | |
