Research ArticleOpen accessPhrase in the titleModeling and Simulation of Projects with Petri NetsS. Kumanan, K. RajaTraditional project management tools and other revised tools are limited in representation of the problem and in dealing situation dynamically. This paper details the use of Petri nets as a graphical and mathematical modeling and simulation tool in project management. In this context, the benefits of Petri nets are indicated. A Petri net aided software, a PETRI-PM is developed to … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,377 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,164 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Definition of Extended High-level Timed Petri NetsCheng Guangming, Liao Minghong, Wu XianghuMany extensions of Petri nets have been proposed to model the behaviors and time relations of embedded system, yet these models are all based on some assumptions about the behaviors of embedded systems. Especially they all do not have the actual ability to model interrupt mechanism of embedded system. A new net which is called Extended High Level Timed Petri … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,039 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePetri Nets and Ladder Logic for Fully-Automating and Programmable Logic Control of Semi-Automatic Machines and SystemsMahmoud A. Barghash, Osama M. Abuzeid, Anas N. Al-Rabadi, Ahmad M. JaradatProblem statement: Automating semi-automatic dynamic machines and complex systems, where some functionalities are already automated but the machine doesn’t run fully in automatic mode, represents another challenge to automating dynamic and manual complex systems. This study deals with a special case of this general problem, where the system’s semi-automatic and automatic functionalities run separately in a sequence with either automatic … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,239 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Fuzzy Petri-Net Based Conceptual Model for Risk Prediction in Enterprise Resource Planning Acquisition Decisions for Small and Medium EnterprisesVijayakumar Bharathi, Dhanya Pramod, Ramakrishnan RamanThis study identifies and evaluates certain critical pitfalls in the acquisition phase of ERP adoption in Small and Medium Enterprises (SMEs) and develops a model for evaluating the risk of failure. On the acquisition stage a set of risks has been identified based on past research work and each of these risks have been explained through a set of well-defined … …Journal of Computer Science, Vol. 9, Issue 1 · 18 Mar 2013 · 7,073 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNovel Mechanism Control Algorithm for Wired NetworkV. B. Kirubanand, S. PalaniammalProblem statement: A critical issue in wireless network where the data can hack by the person and we add a novel encryption mechanism to protect the data transfer from client to server and vice versa. Approach: We present a queuing model of a client and server that uses for bulk arrival service. The arrival of data requests is assumed to … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Petri Net Based Agent Behavioral TestingZina Houhamdi, Belkacem AthamenaIn Multi-Agent System (MAS), developers concentrate on creating design models and evolving them, from higher level models to lower level models, in several steps. Considerable part of MAS implementations is automatically produced from the design models. If a design model contains faults, they are passed to the generated implementations. Practical model validation techniques are required to discover and delete faults … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 10 Sep 2012 · 6,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractFailure Diagnosis on Discrete Event SystemsSihem Kechida, Nasr Eddine DebbacheThe modern technology advances to a point where it is possible and extensively desirable to improve reliability and the technical process safety. This is achieved by computer implanted FDI procedures (Fault Detection and Isolation). However, the malfunction of actuators, sensors and of the process components, as well as erroneous actions of human operators can have some disastrous consequences in high … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,888 accessesView PDFCite
