New Software Tool for Modeling and Control of Discrete-Event and Hybrid Systems Using Timed Interpreted Petri Nets

open access: yesApplied Sciences, 2020
For the development of modern complex production processes in Industry 4.0, it is appropriate to effectively use advanced mathematical models based on Petri nets.

Using Discrete-Event Simulation to Balance Staff Allocation and Patient Flow between Clinic and Surgery

open access: yesModelling, 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]

open access: yesDiscrete 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 ...

Fault-diagnosis in discrete event systems: Improvements and new results

open access: yesAlexandria Engineering Journal, 2011
The malfunction of sensors, actuators, and erroneous actions of human operators can have some disastrous consequences in high risk systems especially if these systems have multiple faults that can lead to undesirable shutdowns and consequently mass ...

On Opacity Verification for Discrete-Event Systems

open access: yesIFAC-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

open access: yesMeasurement + 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 ...

Diagnosis of Deep Discrete-Event Systems

open access: yesJournal of Artificial Intelligence Research, 2020
An abduction-based diagnosis technique for a class of discrete-event systems (DESs), called deep DESs (DDESs), is presented. A DDES has a tree structure, where each node is a network of communicating automata, called an active unit (AU). The interaction of components within an AU gives rise to emergent events.
