Distributed Fault Diagnosis in Discrete Event Systems via Set Intersection Refinements
Keroglou, Christoforos; Hadjicostis, Christoforos N. (2018)We extend and verify diagnosability for a class of set intersection refinement strategies, which can be used for distributed state estimation and fault diagnosis in nondeterministic finite automata that are observed at ...

Probabilistic system opacity in discrete event systems
Keroglou, Christoforos; Hadjicostis, Christoforos N. (2018)In many emerging security applications, a system designer frequently needs to ensure that a certain property of a given system (that may reveal important details about the system’s operation) be kept secret (opaque) to ...

Revised Test for Stochastic Diagnosability of Discrete-Event Systems
Chen, Jun; Keroglou, Christoforos; Hadjicostis, Christoforos N.; Kumar, Ratnesh (2018)This paper provides revisions to the algorithms presented by Chen et al., 2013 for testing diagnosability of stochastic discrete-event systems. Additional new contributions include PSPACE-hardness of verifying strong ...

Verification of AA-Diagnosability in Probabilistic Finite Automata is PSPACE-Hard
Keroglou, Christoforos; Hadjicostis, Christoforos N. (2019)In this paper we consider the complexity of verifying the property of AA-diagnosability in probabilistic finite automata and establish that AA-diagnosability is, in general, a PSPACE-hard problem. In deterministic and ...
