Discrete Event Systems and Deadlock
1990In this paper discrete event systems are defined using trace structures. Special attention will be given to the phenomenon deadlock. Questions we like to answer are: when is there a possibility that two connected systems may end in deadlock, how can it be detected, and how can it be prevented, for example by adding an extra discrete event system.

A conceptual framework for hybrid system dynamics and discrete event simulation for healthcare
Journal of Enterprise Information Management, 2013Purpose – The purpose of this paper is to develop a generic framework for hybrid (integrated deployment of system dynamics and discrete event simulation) simulation which can be applied in the healthcare domain.Design/methodology/approach – As hybrid ...

Predictability in Probabilistic Discrete Event Systems
2016Predictability is a key property allowing one to expect in advance the occurrence of a fault in a system based on its observed events. Existing works give a binary answer to the question of knowing whether a system is predictable or not. In this paper, we consider discrete event systems where probabilities of the transitions are available.

Event‐triggered sliding mode control for discrete‐time singular system
IET Control Theory & Applications, 2018This study focuses on the discrete-time sliding mode control (SMC) based on event-triggered approach for discrete-time singular system. The purpose is to design a SMC law under event-triggered to ensure that the discrete-time singular system is ...

Decentralized Diagnosis of Discrete Event Systems [PDF]
, 2014 Chapter 2 handles the methods and techniques used to achieve the fault diagnosis using a centralized processing structure. It studies two significant event-based approaches of centralized diagnosis of discrete event systems: diagnoser and supervision pattern approaches.

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.

Similarity of Events in Discrete Event Systems
1993In the paper, the similarity of events in the discrete event systems is proposed. Using this, the event hierarchy and the event uncertainty are considered. Following a hierarchical event structure, a concept of macro-events is introduced. To characterise the used formalism, algebraic linguistics and structural pattern recognition techniques are ...

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 ...

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.
