Stochastic Petri net model with random time of Vietnamese ischemic stroke patient treatment process

open access: diamondItalian Journal of Medicine
Simulation is a helpful preliminary step for implementing a patient workflow management system. Simulation is based on the process model (the clinical practice guideline) and the organization model (human and technological resources), permitting the ...

Petri net analysis of a queueing inventory system with orbital search by the server

open access: yesDemonstratio Mathematica, 2023
In this article, a queueing inventory system with finite sources of demands, retrial demands, service time, lead time, (s,S)\left(s,S) replenishment policy, and demands search from the orbit was studied.

TiPeNeSS: A Timed Petri Net Simulator Software with Generally Distributed Firing Delays [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2016
Performance analysis can be carried out in several ways, especially in case of Markovian models. In order to interpret high level of abstraction, we often use modeling tools like timed Petri nets (TPNs). Although some subclasses of TPNs (e.g.

Formal approach on modeling and predicting of software system security: Stochastic petri net [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2015
To evaluate and predict component-based software security, a two-dimensional model of software security is proposed by Stochastic Petri Net in this paper. In this approach, the software security is modeled by graphical presentation ability of Petri nets,

Stochastic Petri Net Based Modeling of Emergency Medical Rescue Processes during Earthquakes

open access: yesJournal of Systems Science and Complexity, 2021
The post-disaster emergency medical rescue (EMR) is critical for people’s lives. This paper presents a stochastic Petri net (SPN) model based on the process of the rescue structure and a Markov chain model (MC), which is applied to the optimization of ...

An Advanced Environment for Hybrid Modeling of Biological Systems Based on Modelica

open access: yesJournal of Integrative Bioinformatics, 2011
Biological systems are often very complex so that an appropriate formalism is needed for modeling their behavior. Hybrid Petri Nets, consisting of time-discrete Petri Net elements as well as continuous ones, have proven to be ideal for this task ...
