The control of discrete event systems
Proceedings of the IEEE, 1989A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Such systems arise in a variety of contexts ranging from computer operating systems to the control of complex multimode processes.

Uncertainty on Discrete-Event System Simulation
ACM Transactions on Modeling and Computer Simulation, 2021Uncertainty Propagation methods are well-established when used in modeling and simulation formalisms like differential equations. Nevertheless, until now there are no methods for Discrete-Dynamic Systems. Uncertainty-Aware Discrete-Event System Specification (UA-DEVS) is a formalism for modeling Discrete-Event Dynamic Systems that include uncertainty ...

Diagnosability of discrete event systems
IEEE Transactions on Automatic Control, 1995The authors study the diagnosability of discrete-event systems. Failure detection and isolation is an important task in the automatic control of large, complex systems. A discrete event system (DES) approach to the problem of failure diagnosis is proposed in this work.

Discrete-event dynamic systems
IEEE Transactions on Control Systems Technology, 1999The supervisory control theory of discrete-event dynamic systems (DEDS), first introduced by Ramadge and Wonham, is based on an automata concept. Given a process, the objective of this theory is to design a supervisor in such a way that the process coupled with the supervisor behaves according to various constraints.

Modeling a System with Discrete Events
2012 Sixth UKSim/AMSS European Symposium on Computer Modeling and Simulation, 2012The goal of this paper is to differentiate and apply the idiosyncratic and significant characteristics of the structuring and formalization of systems of discrete events in a methodological approach to the building of discrete imitational models. This approach is based on studying the particular system, beginning with a general overview and then ...

On observability of discrete-event systems
Information Sciences, 1988The supervised discrete-event system is considered. The set of possible events is partitioned into the sets of controllable and observable events. State transitions are governed by the language generated by the transition function and the alphabet of event labels.

Detectability of Discrete Event Systems
IEEE Transactions on Automatic Control, 2007In this note, we investigate the detectability problem in discrete event systems. We assume that we do not know initially which state the system is in. The problem is to determine the current and subsequent states of the system based on a sequence of observations.

Identification in discrete event systems
SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002This paper presents a method to identify discrete event systems (DES) using interpreted Petri nets (IPN). The approach herein proposed works online with the system and has two main steps. In the first step, the algorithm advances finding out new places, transitions and arcs, all of them are obtained using input-output information.
