Research ArticleOpen accessIn the author namesA 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 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the author namesFolding of Trefoil Knot and its GraphM. El-Ghoul, A. I. Elrokh, M. M.A. ShamiriIn this study, we introduce the effect of the folding, conditional folding, retraction and conditional retraction on trefoil knot and its graph. We introduce the sheeted trefoil knot and the folding and retraction of this type and present the limit of foldings. We study how to obtain the types of link graph by adjacency matrix for any number of vertices … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the author namesSoftware Process Modeling Using Role and CoordinationAtil Fadila, Ghoul Said, Bounour NoraThe term software process joins all activities that have to be achieved in order to develop software. It has been shown that modeling such processes is difficult and expensive task. It's confirmed by diversity of software processes modeling approaches which are however, not satisfactory. This study deals with an area of growing importance and presents a role- and coordination- based … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,575 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Comparative Classification of Aspect Mining ApproachesBounour Nora, Ghoul Said, Atil FadilaIn object oriented paradigm, the implementation of a concern is typically scattered over many locations and tangled with the implementation of other concerns, resulting in a system that is hard to explore and understand. Identifying such code automatically greatly improves both the maintainability and the evolveability of the application. Aspect mining aims to identify crosscutting concerns in existing systems, thereby … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the author namesTowards Autonomously Developed Software: A genetic Approach in Critical and Embedded SystemsDjamel Meslati, Saïd GhoulNowadays, we are still considering changes undergone by a software system as a sporadic phenomenon and we do not sufficiently anticipate future changes during the development phase. Consequently, many problems arise in the maintenance phase. In this study, we present an approach where all changes undergone by a software system are considered as its ontogenetic dimension. We represent this dimension … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,196 accessesView PDFCite
