Download or read book Gestion de flotte avec fen tres horaires written by and published by . This book was released on 2002 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur l'application de la programmation par contraintes au domaine des problèmes de gestion de flotte de véhicules avec contraintes de temps. Le chapitre 1 donne une description du paradigme de la programmation par contraintes et la manière dont elle peut être utilisée pour résoudre des problèmes d'optimisation combinatoire. Le chapitre 2 passe en revue la littérature pertinente concernant les combinaisons de programmation par contraintes et de recherche opérationnelle qui permettent de résoudre les problèmes de gestion de flotte. Les chapitres 3, 4 et 5, dont le texte est en anglais, détaillent les 3 volets du programme de recherche, à savoir : l'intégration de la programmation par contraintes à des méthodes de recherche locale; la résolution de manière exacte du problème de confection de tournées de véhicules avec fenêtres de temps; l'utilisation de la programmation par contraintes dans le cadre de problèmes de gestion de flotte en temps réel.

This book was released on 2008 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans ce mémoire, nous étudions les problèmes de tournées de véhicules sur nœuds et sur arcs qui sont les deux grands types de problèmes de tournées, rencontrés dans la majorité des applications de transport. Nous nous intéressons plus particulièrement aux cas avec fenêtres horaires ou préemption des tâches. Ce travail est décomposé en deux grandes parties. La première partie est consacrée aux problèmes de tournées sur nœuds et sur arcs avec fenêtres horaires (VRPTW pour Vehicle Routing Problem with Time Windows et CARPTW pour Capacitated Arc Routing Problem with Time Windows). Contrairement au VRPTW qui a fait l’objet d’une recherche intensive ces dix dernières années, peu de travaux ont porté sur le CARPTW. Dans cette partie de la thèse, nous proposons une méthode basée sur la métaheuristique GRASP couplée à une technique de reconnexion de chemins (path-relinking) pour le CARPTW et un algorithme mémétique pour le VRPTW. La deuxième partie de cette thèse porte sur les problèmes de tournées de véhicules sur nœuds et sur arcs avec préemption de la demande (SDVRP pour Split Delivery Vehicle Routing Problem et SDCARP pour Split Delivery Capacitated Arc Routing Problem). Vu que le SDCARP est un problème relativement nouveau, nous avons commencé par élaborer des modèles mathématiques. Nous avons ensuite proposé des bornes inférieures et supérieures. Les bornes inférieures sont obtenues par des méthodes de coupes, alors que les bornes supérieures sont déterminées par un algorithme mémétique avec gestion de la population et une nouvelle métaheuristique. L’algorithme mémétique a été aussi adapté au SDVRP, donnant lieu à des résultats très compétitifs avec ceux déjà publiés

This book was released on 1999 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous nous sommes intéressés dans ces travaux à un problème de composition d'une flotte hétérogène de véhicules et la conception des tournées associées respectant des contraintes telles, la capacité des véhicules, les fenêtres de temps chez le client, les temps d'attente, etc. après description du problème et sa modélisation pour une application particulière à la collecte postale, ainsi que toutes les caractéristiques et difficultés dont il faut tenir compte pendant sa résolution, nous présentons deux méthodes de résolution : une méthode exacte et une autre approchée. La méthode exacte est fondée essentiellement sur les techniques de génération de colonnes avec comme difficulté majeure, la résolution du sous-problème- plus court chemin contraint- pour lequel nous avons élabore un algorithme qui repose sur la programmation dynamique et l'exploration A*. La difficulté des instances traitées nous a poussé à construire une méthode approchée - méthode tabou à voisinage variable - qui repose sur un ensemble de mouvements, locaux et globaux, susceptibles de modifier considérablement la structure de la solution et de pouvoir traiter par conséquent des instances beaucoup plus grandes contrairement à la méthode exacte.

This book was released on 2005 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse traite de la gestion d'une flotte de véhicules en temps réel. Les récentes améliorations dans les technologies de la communication et de l'information fournissent de nouveaux flots de données en temps réel qui conduisent au développement de nouvelles applications dans le domaine des transports. De nouvelles méthodes d'aide à la décision sont à développer afin d'assister le gestionnaire de la flotte dans sa tâche de planification des activités des véhicules. Le problème support de cette thèse est le problème de tournées de véhicules avec contraintes de ramassage et de livraison, de fenêtres de temps et une flotte de taille finie. Tout d'abord, nous proposons des heuristiques constructives ainsi qu'une approche basée sur la recherche tabou permettant d'optimiser la planification lorsque l'ensemble des demandes à affecter aux véhicules est connu a priori. La principale contribution réside en la définition de techniques d'extraction et d'exploitation d'informations permettant une réduction de l'espace de recherche, ce qui résulte en une diminution sensible de la durée de résolution. Lorsque certaines demandes parviennent au gestionnaire alors que les véhicules sont en route, une gestion en temps réel est nécessaire. Pour résoudre ce problème, nous capitalisons sur les méthodes définies pour le cas statique afin de définir une adaptation au contexte temps réel. Les travaux réalisés se sont inscrits dans le cadre du projet TESS (Transport ESpace et Société). Les méthodes définies ont été intégrées dans un moteur d'optimisation, inclus au sein d'un logiciel de gestion de la flotte développé en collaboration avec les partenaires du projet (le CNES et la société CGx).

Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

This book was released on 2018-05-08 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean covers 70 percent of the Earth’s surface, and is essential for life on our planet – even for those of us who live nowhere near the sea! It provides us all with food and other materials that we need, regulates our climate and provides half of the oxygen we breathe. The ocean also offers us various means of transport and opportunities for recreation. People have long thought that the ocean was so wide and bountiful that it would go on supplying our needs forever, but this is not the case: human activities are causing significant damage to life in the ocean. People are often unaware of the problems created by this heavy reliance, as few of us have the opportunity to look beneath the surface of the sea and see the damage that our actions have caused. This is where the Ocean Challenge Badge comes in: let it take you on a journey to discover the ocean! It is packed with activities to help you learn about how the ocean works, the creatures that live in it, and just how important it is in our everyday lives. You will also discover how YOU can play a role in protecting our ocean for future generations. We hope you will be inspired to take the challenge and celebrate our ocean. So dive in and begin your aquatic discoveries!
Download or read book Albert Cohen written by Jack I. Abecassis and published by JHU Press. This book was released on 2020-03-03 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honorable Mention winner in the Modern Language Association's Aldo and Jeanne Scaglione Prize competition for French and Francophone Literary Studies A major figure in twentieth-century letters, Albert Cohen (1895–1981) left a paradoxical legacy. His heavily autobiographical, strikingly literary, and polyphonic novels and lyrical essays are widely read by a devout public in France, yet have been largely ignored by academia. A self-consciously Jewish writer and activist, Cohen remained nevertheless ambivalent about Judaism. His self-affirmation as a Jew in juxtaposition with his satirical use of anti-Semitic stereotypes still provokes unease in both republican France and institutional Judaism. In Albert Cohen: Dissonant Voices, the first English-language study of this profound and profoundly misunderstood writer, Jack I. Abecassis traces the recurrent themes of Cohen's works. He reveals the dissonant fractures marking Cohen as a modernist, and analyzes the resistance to his work as a symptom of the will not to understand Cohen's main theme—"the catastrophe of being Jewish."For Abecassis, Cohen's diverse oeuvre forms a single "roman fleuve" exploring this perturbing theme through fragmentation and grotesquerie, fantasies and nightmares, the veiling and unveiling of the unspeakable. Abecassis argues that Cohen should not be read exclusively through the prism of European literature (Stendhal, Tolstoy, Proust), but rather as the retelling—inverting and ultimately exhausting, in the form of submerged plots—of the Biblical romances of Joseph and Esther. The romance of the charismatic Court Jew and its performance correlative, the carnival of Purim, generate the logic of Cohen's acute psychological ambivalence, historical consciousness and carnal sensuality—themes which link this modernist author to Genesis as well as to the literary practices of Sephardic crypto-Jews. Abecassis argues that Cohen's best-known work, Belle du Seigneur (1968), besides being an obvious tale of obsessive love and dissolution, is foremost a tale of political intrigue involving Solal, the meteoric-rising Jew in the League of Nations during the period of Appeasement (1936), and his ultimate self-destruction. Providing close readings and imaginative analyses of the entire literary output of one of twentieth-century France's most important Jewish writers, Abecassis presents here a major work of literary scholarship, as well as a broader study of the reception and influence of Jewish thought in French literature and philosophy.
