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.

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.

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.

Algebras of discrete event models
Proceedings of the IEEE, 1989The authors consider discrete event models (DEMs) that describe logical system behavior, i.e. mathematical models that represent the set of traces of sequences of events that the system can execute. Examples of DEM formalisms include state machines, Petri nets, and Hoare's communicating sequential processes. All these formalisms are algebras, i.e.

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.

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 Events in Power Systems
Discrete Event Dynamic Systems, 1999The relevance of Discrete Event System theory (whether synthetic or analytic) to power system analysis and control is not clear. However, based on several characterizations of the domain of discrete systems set forth in the January 1989 Special Issue of the IEEE Proceedings, on ’’Dynamics of discrete event systems‘‘ (Ho, 1989), we attempt to delineate ...

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.

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.

Combining Discrete Event Simulations and Event Sourcing
Proceedings of the Seventh International Conference on Simulation Tools and Techniques, 2014Discrete event simulations (DES) represent the status quo for many different types of simulations. There are still open challenges, such as designing distributed simulation architectures, providing development and debugging support, or analyzing and evaluating simulation runs.
