A Fast Discrete Event Simulation Model for Queueing Network Systems [PDF]
EAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2016 Based on Lindley's recursive equations for G/G/1 systems, this paper proposes a Fast Discrete Event Simulation (FDES) model for queueing networks. Equations for multiplexer and de-multiplexer elements are presented, which allows to simulate not only

Modelling, 2023 We consider the problem of system-level balanced scheduling in a pediatric hospital setting. A hospital clinic has a queue for patients needing care. After being seen in clinic, many require follow-up surgery, for which they also wait in a queue.

Tail Asymptotics for Discrete Event Systems [PDF]
Discrete Event Dynamic Systems, 2006 In the context of communication networks, the framework of stochastic event graphs allows a modeling of control mechanisms induced by the communication protocol and an analysis of its performances. We concentrate on the logarithmic tail asymptotics of the stationary response time for a class of networks that admit a representation as (max,plus)-linear ...

On Opacity Verification for Discrete-Event Systems
IFAC-PapersOnLine, 2020 Opacity is an information flow property characterizing whether a system reveals its secret to an intruder. Verification of opacity for discrete-event systems modeled by automata is in general a hard problem. We discuss the question whether there are structural restrictions on the system models for which the opacity verification is tractable.

Fault diagnosis of PLC-based discrete event systems using Petri nets
Measurement + Control, 2022 This paper addresses the fault diagnosis problem of PLC-based systems that can be modeled as Petri nets under a certain level of abstraction. The existing Petri-net-based fault diagnosis approaches often associate transitions and/or places with sensors ...

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.
