Discrete-event systems subject to unknown sensor attacks
, 2022 This work is set in the context of supervisory control of discrete-event systems under partial observation. Attackers that are able to insert or erase occurrences of particular output symbols can tamper with the supervisor’s observation and by doing so ...

Diagnosis of Deep Discrete-Event Systems
Journal of Artificial Intelligence Research, 2020 An abduction-based diagnosis technique for a class of discrete-event systems (DESs), called deep DESs (DDESs), is presented. A DDES has a tree structure, where each node is a network of communicating automata, called an active unit (AU). The interaction of components within an AU gives rise to emergent events.

Generalised verification of the observer property in discrete event systems
, 2012 The observer property is an important condition to be satisfied by abstractions of Discrete Event Systems (DES) models. This paper presents a generalised version of a previous algorithm which tests if an abstraction of a DES obtained through natural ...

Conflict-preserving abstraction of discrete event systems using annotated automata
, 2012 This paper proposes to enhance compositional verification of the nonblocking property of discrete event systems by introducing annotated automata. Annotations store nondeterministic branching information, which would otherwise be stored in extra states ...

Failure diagnosis in real time stochastic discrete event systems
Engineering Science and Technology, an International Journal, 2015 Discrete Event System (DES) has been used for Failure Detection and Diagnosis (FDD) of a wide range of systems. For real time systems, timed DES based frameworks diagnose failures leading to violation of delays or deadlines.

Model Abstraction for Discrete-Event Systems Using a SAT Solver
IEEE Access, 2023 Model abstraction for finite state automata is beneficial to reduce the complexity of discrete-event systems (DES), enhance the readability and facilitate the control synthesis and verification of DES.

Weak Diagnosability of Discrete Event Systems
IFAC-PapersOnLine, 2020 Abstract In this paper, we propose a weaker property for failure diagnosis called weak diagnosability. Weak diagnosability says that, after the occurrence of a fault event, for any continuation, there always exists at least one trajectory of sufficient length along which we can diagnose the occurrence of the fault event.

The Use of Language Projection for Compositional Verification of Discrete Event Systems
, 2008 This paper proposes the use of abstraction by language projection to improve the performance of compositional verification to prove or disprove that a large system of composed finite-state machines satisfies a given safety property.

Language Recovery in Discrete-Event Systems against Sensor Deception Attacks
Mathematics, 2023 Cyber-physical systems are characterized by the intrinsic combination of software and physical components that usually include (wired and wireless) communication devices, sensors, actuators, and control processing units. Some wireless devices communicate
