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.

Parallel Discrete-Event Simulation
IEEE Design & Test of Computers, 1987The availability of commercial multiprocessors gives a new importance to distributed simulation. However, while existing techniques exploit some levels of parallelism in the discrete-event simulation algorithm, they are usually targeted to specific applications and architectures.

Discrete-event simulation and the event horizon
ACM SIGSIM Simulation Digest, 1994The event horizon is a very important concept that is useful for both parallel and sequential discrete-event simulations. By exploiting the event horizon, parallel simulations can process events in a manner that is risk-free (i.e., no antimessages) in adaptable “breathing” time cycles with variable time widths.

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.

Lossless Event Compression of Discrete Event Systems
IEEE Transactions on Automatic Control, 2021This article investigates the lossless event compression problem of discrete event systems which is, given a discrete event system and a source string generated by it, to find a minimal recoverable compressed string by removing as many events as possible. In order for the problem to be well post, two compression protocols are introduced.

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 ...

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.

How to draw event models to specify the synchronisation of concurrent information objects - the key issue in combining federated systems or distributing a single one. Simple patterns in object interaction analysis. The difference between a real-world enterprise model, a logical application model and the implementations of the logical application model.

Discrete-event simulation in Ada
Proceedings of the 1987 annual ACM SIGAda international conference on Ada - SIGAda '87, 1987This paper presents two approaches for doing discrete-event simulation in Ada. One approach is based on coroutines, and the other solely uses the pseudo-parallel execution scheme of Ada tasks. Concerning coroutines, we present two techniques to implement them.

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.
