Failure Diagnosis for Distributed Stochastic Discrete Event Systems

Failure Diagnosis for Distributed Stochastic Discrete Event Systems

Because of the complexity of the failure diagnosis for large-scale discrete event systems (DESs), DESs with decentralized information have received a lot of attention. DESs with communication events are defined as distributed DESs. Stochastic discrete event systems (SDESs) are DESs with a probabilis...
