This research focuses on the forbidden state problem in the framework of labeled Petri nets
(LPNs), ie, to design a supervisor for a plant modeled by an LPN such that the closed-loop …

In this paper, we study the nonblocking supervisor synthesis problem in partially observed
discrete event systems modeled by finite-state automata. We consider a particular type of …

The system requirement specifications (SRSs) of the train control system (TCS) are the
starting point and foundation of system design and development. Defects in the SRSs will …

This work addresses the verification of current-state opacity with respect to a real-time
observation generated from time-dependent systems. The secret behavior of a time …

This work focuses on Real-time system models based on the Time Petri Net (TPN) formalism
and addresses a pathological aspect known to often affect models of Real-Time Systems …

This article addresses the problem of verifying co-detectability for a labeled Petri net (LPN)
that is observed at multiple observation sites, each with its own observation map. A system is …

Opacity is an important system property that is particularly relevant in the context of system
security and privacy. A system is considered opaque if the predefined secret behavior of the …

Train communication network (TCN) is an important guarantee for the reliable and safe
operation of high‐speed rail train. The higher reliability of the TCN is, the safer operation of …

In this work, we address the codiagnosability analysis problem of a networked discrete event
system under malicious attacks. The considered system is modeled by a labeled Petri net …

With its ability to operate at high speeds and capacity, high-speed rail offers a fast,
dependable, and ecofriendly urban transportation option. Safety-critical systems such as …
