This book was released on 2004 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le premier chapitre de cette thèse est dédié à un état de l'art sur le problème central disjonctif ainsi que sur des problèmes apparentés. Le second traite de problèmes à une machine et de type job-shop tenant compte de contraintes de disponiblilité où les opérations peuvent être sécables ou non et les fenêtres traversables ou non. Pour résoudre les deux problèmes nous proposons une procédure par séparation-évalutation. Le troisième chapitre présente des relaxations pour le problème du flow-shop basées sur des contraintes associées aux positions des opérations. Nous montrons que ce principe permet d'obtenir des bornes inférieures compétitives pour différents problèmes. Dans le quatrième chapitre, nous abordons un problème de flow-shop où nous considérons que les opérations nécessitent l'utilisation d'une ressource supplémentaire lors de leur phase de préparation. Nous montrons certains résultats théoriques, et nous proposons des méthodes de résolution pour un problème à deux machines. Dans le dernier chapitre, nous présentons les travaux que nous avons effectués pour la réalisation du produit Direct Planning commercialisé par la société Volume Software.

This book was released on 1997 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA PROGRAMMATION PAR CONTRAINTES EST UN OUTIL PUISANT QUI PERMET DE RESOUDRE DE FACON ASSEZ NATURELLE DES PROBLEMES COMPLEXES. EN EFFET, L'IDEE DE CE TYPE DE PROGRAMMATION EST DE DECRIRE LES PROPRIETES QUE DOIVENT REMPLIR LES SOLUTIONS AUX MOYENS D'UN SYSTEME DE CONTRAINTES PLUTOT QUE LES MECANISMES QUI MENENT A CES SOLUTIONS. TOUTEFOIS, AFIN DE MAINTENIR DES PERFORMANCES ACCEPTABLES, LES LANGAGES DE CETTE CATEGORIE REPOSENT SUR DES ALGORITHMES DE RESOLUTION QUI NE PEUVENT FOURNIR QUE DES SOLUTIONS APPROCHEES (P.EX. EXPRIMEES AU MOYEN D'INTERVALLES). AINSI, L'OBTENTION DE SOLUTIONS EXACTES NECESSITE SOIT DES SYSTEMES DE CONTRAINTES PLUS COMPLEXES SOIT L'EMPLOI DE CONTRAINTES SPECIFIQUES. POUR CE TRAVAIL DE RECHERCHE, NOUS NOUS SOMMES INTERESSES A UN PROBLEME D'ORDONNANCEMENT DIFFICILE, LE PROBLEME DU JOB-SHOP, POUR LEQUEL NOUS AVONS ESSAYE DE CONCEVOIR UNE APPROCHE PROGRAMMATION PAR CONTRAINTES. CETTE ETUDE NOUS A CONDUIT A L'ELABORATION DE DEUX NOUVEAUX CONCEPTS, LES ENSEMBLES-INDEX ET LES PATRONS DE CONTRAINTES, QUI PERMETTENT LA PRODUCTION AUTOMATIQUE DE CONTRAINTES EN COURS DE RESOLUTION. CE DOCUMENT COMPREND DEUX PARTIES. DANS UN PREMIER TEMPS NOUS ETUDIONS LES MECANISMES DE RESOLUTION USUELS EMPLOYES POUR TRAITER LES PROBLEMES DISCRETS. L'ACCENT EST MIS SUR LES PARTICULARITES ET LES LIMITATIONS DE CES ALGORITHMES. LES ENSEMBLES-INDEX ASSOCIES AUX PATRONS DE CONTRAINTES SONT ENSUITE PRESENTES COMME UN MOYEN DE LEVER LES RESTRICTIONS PRECEDEMMENT SOULIGNEES. LES ALGORITHMES REQUIS SONT ALORS PRESENTES PUIS VIENT UNE DESCRIPTION DETAILLEE DU PROTOTYPE QUE NOUS AVONS REALISE. LA SECONDE PARTIE PRESENTE L'APPLICATION DE NOTRE SYSTEME AU PROBLEME D'ORDONNANCEMENT A CONTRAINTES DISJONCTIVES (OU JOB-SHOP). APRES UN TOUR D'HORIZON DES DIVERSES TECHNIQUES DE RESOLUTION CLASSIQUES, NOUS EXPOSONS NOTRE METHODE QUI EXPLOITE LES MECANISMES DEVELOPPES AUPARAVANT. BIEN QU'ESSENTIELLEMENT CONSTITUE D'UN SYSTEME DE CONTRAINTES ET D'UNE STRATEGIE D'ENUMERATION, NOTRE ALGORITHME OFFRE DES PERFORMANCES COMPARABLES VOIRE MEME SUPERIEURES A DES IMPLANTATIONS DEDIEES QUI UTILISENT POURTANT DES METHODOLOGIES SENSIBLEMENT PLUS SOPHISTIQUEES

Book excerpt: LES PROBLEMES D'ORDONNANCEMENT DISJONCTIFS CONSTITUENT UN DES ARCHETYPES DE PROBLEMES D'OPTIMISATION COMBINATOIRE DIFFICILES A CE JOUR. CETTE THESE EST CONSACREE A L'ETUDE DES OUTILS QUI CONDITIONNENT LA PERFORMANCE DES METHODES DE RESOLUTION EXACTE POUR CE TYPE DE PROBLEME. DANS LA PREMIERE PARTIE DU MEMOIRE, NOUS PASSONS EN REVUE LES PRINCIPALES REGLES DISJONCTIVES CLASSIQUES ET PROPOSONS QUELQUES REGLES ORIGINALES, DONT LE SHAVING LOCAL SUR ENSEMBLES. UNE PROCEDURE CALCULANT LES AJUSTEMENTS OPTIMAUX DES FENETRES TEMPORELLES EST EGALEMENT DEFINIE. LES EXPERIMENTATIONS NUMERIQUES EFFECTUEES A L'AIDE DE CETTE TECHNIQUE SUR LE PROBLEME DE JOB-SHOP MONTRENT QUE LES AJUSTEMENTS SUR ENSEMBLES ASCENDANTS/DESCENDANTS DE J. CARLIER ET E. PINSON COMBINES AU SHAVING LOCAL SUR ENSEMBLES OBTIENNENT LA QUASI-TOTALITE DES AJUSTEMENTS REALISABLES AU NIVEAU D'UNE MACHINE. CECI CONSIDERE, NOUS PROPOSONS DANS UN SECOND TEMPS D'ETENDRE LES REGLES CLASSIQUES DANS LE CAS PARTICULIER DU FLOW-SHOP DE PERMUTATION, EN EXAMINANT CETTE FOIS DES COUPLES DE MACHINES. L'ALGORITHME SERIE-PARALLELE DE C. L. MONMA ET J. B. SIDNEY PERMET EN EFFET DE DEFINIR DE NOUVELLES REGLES ET BORNES A PARTIR DE SOUS-PROBLEMES POLYNOMIAUX A DEUX MACHINES. LES TESTS REALISES INDIQUENT QUE LES REGLES A DEUX MACHINES APPORTENT UN GAIN SIGNIFICATIF POUR LES PROBLEMES DE FLOW-SHOP ASSOCIANT DES JOBS DE TAILLES HETEROGENES. POUR COMPLETER CETTE ETUDE, NOUS NOUS INTERESSONS FINALEMENT A LA MINIMISATION DU COUT TOTAL POUR LE PROBLEME A UNE MACHINE. NOUS MONTRONS EN PARTICULIER QU'UNE TECHNIQUE DE PROGRAMMATION DYNAMIQUE INDEXEE SUR LE TEMPS UTILISANT UNE MEMOIRE A COURT TERME RESOUT EN TEMPS PSEUDO-POLYNOMIAL UNE CLASSE DE PROBLEMES A FENETRES TEMPORELLES CONTRAINTES. L'INTEGRATION DE CET ALGORITHME DANS UNE RELAXATION LAGRANGIENNE PERMET D'OBTENIR UNE BORNE INFERIEURE POUR LE CAS GENERAL. CELLE-CI S'AVERE EN PARTICULIER D'EXCELLENTE QUALITE POUR LE PROBLEME DE LA MINIMISATION DU NOMBRE DE TACHES EN RETARD.
Download or read book Cambridge Yearbook of European Legal Studies Vol 13 2010 2011 written by Catherine Barnard and published by Bloomsbury Publishing. This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Download or read book Vehicular Networks written by André-Luc Beylot and published by John Wiley & Sons. This book was released on 2013-06-12 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years vehicular networks have been receiving a lot of attention from academia, industry, standardization bodies, and the various transportation agencies and departments of many governments around the world. It is envisaged in the next decade that the Intelligent Transportation System (ITS) will become an essential part of our daily life. This book describes models and/or algorithms designed to investigate evolutionary solutions to overcome important issues such as congestion control, routing, clustering, interconnection with long-term evolution (LTE) and LTE advanced cellular networks, traffic signal control and analysis of performances through simulation tools and the generation of vehicular mobility traces for network simulations. It provides an up-to-date progress report on the most significant contributions carried out by the specialized research community in the various fields concerned, in terms of models and algorithms. The proposals and new directions explored by the authors are highly original, and a rather descriptive method has been chosen, which aims at drawing up complete states of the art as well as providing an overall presentation of the personal contributions brought by the authors and clearly illustrating the advantages and limitations as well as issues for future work.
