What is Fault Diagnosis in Petri Nets?
Fault diagnosis in Petri nets involves constructing diagnosers and verifying fault detectability and isolability in Petri net models of concurrent discrete event systems.
Research focuses on handling unobservable transitions and distributed structures for fault detection (Cabasino et al., 2010, 344 citations). Studies extend to opacity verification and place-bordered nets for modular diagnosis (Tong et al., 2016, 265 citations; Genç and Lafortune, 2007, 140 citations). Over 1,000 papers address timed, stochastic, and interpreted Petri nets for DES fault diagnosis.
Why It Matters
Fault diagnosis using Petri nets enables timely fault isolation in manufacturing assembly lines, improving reliability (Seybold et al., 2015). It supports safety-critical systems like battery production by modeling concurrent faults with place-bordered nets (Genç and Lafortune, 2007). Applications in Industry 4.0 address control challenges, reducing downtime through diagnosability analysis (Grobelna and Karatkevich, 2021).
Key Research Challenges
Unobservable Transitions Handling
Fault detection requires identifying faults despite unobservable transitions in Petri nets (Cabasino et al., 2010). Diagnosers must distinguish fault trajectories from normal ones without full observation. This complicates reachability analysis in large nets.
Distributed Modular Diagnosis
Place-bordered Petri nets model coupled components, but distributed diagnosis faces communication delays (Genç and Lafortune, 2007). Local diagnosers must coordinate for global fault isolation. Scalability limits apply to large manufacturing systems.
Opacity and Secrecy Verification
State-based opacity verification ensures secret behaviors remain hidden in Petri nets (Tong et al., 2016). Fault diagnosis must balance opacity with detectability. Computational complexity arises in verifying opaque languages.
