Book excerpt: Les travaux de cette thèse réalisée sous contrat CIFRE portent sur des problématiques d’ordonnancement de projets mufti-compétences. Définis en collaboration avec des experts de gestion de projet au sein de la société Néréide, deux modèles d’ordonnancement de projet font l’objet de cette étude. Dans le premier modèle, une tâche est définie par l’ensemble des compétences dont elle a besoin, la charge nécessaire de chaque compétence ainsi que la possibilité d’être interrompue ou non. Pour l’élaboration d’un planning prédictif respectant toutes les contraintes et minimisant la date de fin du projet, nous proposons des heuristiques de liste et métaheuristiques. Un modèle mathématique linéaire en nombres entiers ainsi que des bornes inférieures sont également développés. Dans un second temps, nous proposons, à partir d’un planning prédéfini, des méthodes pour ajuster le planning et répondre aux aléas survenus lors du déroulement du projet. Pour résoudre ce problème réactif, nous proposons une approche exacte itérative basée sur une formulation linéaire en nombres entiers ainsi qu’un algorithme génétique de type NSGA-II. Il s’agit donc d’une approche réactive bicritère où les solutions calculées doivent minimiser à la fois la date d’achèvement du projet et le nombre maximum de changements d’affectation de tâches aux employés. Dans le deuxième modèle, un cas particulier du modèle préemptif précédent est étudié. Nous nous intéressons au cas où une tâche nécessite une seule compétence avec possibilité de préemption seulement si les ressources ne sont pas disponibles (absence, congés, etc.). Dans ce modèle, une tâche est définie également par sa date de disponibilité et une date de fin souhaitée. Un coût d’utilisation personne/compétence est introduit. Pour ce dernier modèle, il s’agit d’un problème d’ordonnancement de projet bicritère, pour lequel les solutions calculées doivent minimiser le retard maximum et le coût global d’affectation des personnes aux tâches. Des heuristiques et métaheuristiques sont proposées pour ce modèle. Certaines méthodes de résolution proposées ont été implémentées sous forme d’add-ons intégrables au framework OFBiz.

Download or read book Handbook on Project Management and Scheduling Vol 1 written by Christoph Schwindt and published by Springer. This book was released on 2015-01-13 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasing importance of product differentiation and collapsing product life cycles, a growing number of value-adding activities in the industry and service sector are organized in projects. Projects come in many forms, often taking considerable time and consuming a large amount of resources. The management and scheduling of projects represents a challenging task, and project performance may have a considerable impact on an organization's competitiveness. This handbook presents state-of-the-art approaches to project management and scheduling. More than sixty contributions written by leading experts in the field provide an authoritative survey of recent developments. The book serves as a comprehensive reference, both, for researchers and project management professionals. The handbook consists of two volumes. Volume 1 is devoted to single-modal and multi-modal project scheduling. Volume 2 presents multi-project problems, project scheduling under uncertainty and vagueness, managerial approaches and a separate part on applications, case studies and information systems.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet outil permet de sélectionner la meilleure solution de compromis selon les critères définis par l'utilisateur. Mis à part la durée et le coût du projet, le temps perdu est le troisième critère étudié, il s'agit du temps d'inactivité d'une ressource entre deux activités. Pour effectuer le choix de la solution finale, les trois critères sont pris en considération à poids égaux. D'autres simulations sont effectuées pour des poids différents afin d'observer l'évolution du rangement. Cette étude contribue à la recherche en proposant une méthode de résolution pour deux extensions du problème d'ordonnancement d'un projet avec contraintes de ressources, les objectifs multiples et les compétences multiples. -- Mot(s) clé(s) en français : RCPSP, objectifs multiples, compétences multiples, gestion de projet, métaheuristique, Midaco, Prométhée, optimisation, points de Pareto. »--

This book was released on 2009 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objet de cette thèse est l’étude et la résolution d’un problème industriel de gestion de projet sous contraintes de ressources. Notre problème intègre des contraintes rencontrées dans des ateliers d’assemblage d’avions et essaie de se rapprocher des pratiques et des méthodes de travail dans ces ateliers. Nous introduisons les problèmes dits d’ordonnancement sous conditions d’admissibilité des modes. Nous caractérisons d’abord notre problème comme une nouvelle extension du problème RCPSP (Resource-Constrained Project Scheduling Problem). Ensuite, nous proposons pour le cas non préemptif, un modèle mathématique pour résoudre des instances de petites tailles. Ce modèle peut s’étendre au problème d’ordonnancement sous conditions d’admissibilité des modes sous réserve que les conditions d’admissibilité soient linéaires. Différentes formulations du modèle mathématique opèrent sur des problèmes relaxés et permettent d’obtenir des bornes inférieures pour le problème global (ou non relaxé). Nous présentons également notre générateur d’instances et les bornes inférieures utilisées. Enfin, nous présentons deux heuristiques et une métaheuristique pour la résolution de notre problème. Les méthodes proposées sont comparées avec une problématique de la littérature qui est proche de notre problème.

Download or read book Managing Interdisciplinary Projects written by Stephen Emmitt and published by Routledge. This book was released on 2010-04-26 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction, architecture and engineering projects are complex undertakings, involving a temporary grouping of people and companies, with different agendas and experience, coming together to achieve a project goal. This book investigates the dynamics of the relationships between individuals involved in architecture, engineering and construction projects. It combines a structured theoretical framework, derived from social psychology and mainstream management theory, with case studies and research from the built environment sector. Focusing on how people interact, communicate and work together, it examines how best to manage the interdisciplinary relationships that form and reform during the project life cycle. The book covers vital areas of project management, whose importance has recently come to be recognized, and will be valuable for students at both undergraduate and graduate level. Practitioners will also find it a useful insight into the social aspect of project management, with implications and applications that apply to all projects in the built environment sector.

Download or read book The Use of Force in International Law written by Tarcisio Gazzini and published by Routledge. This book was released on 2017-07-05 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of essays examines the development of political and legal thinking regarding the use of force in international relations. It provides an analysis of the rules on the use of force in the political, normative and factual contexts within which they apply and assesses their content and relevance in the light of new challenges such as terrorism, weapons of mass destruction and cyber-attacks. The volume begins with an overview of the ancient and medieval concepts of war and the use of force and then concentrates on the contemporary legal framework regulating the use of force as moulded by the United Nations Charter and state practice. In this regard it discusses specific issues such as the use of force by way of self-defence, armed reprisals, forcible reactions to terrorism, the use of force in the cyberspace, humanitarian intervention and the responsibility to protect. This collection of previously published classic research articles is of interest to scholars and students of international law and international relations as well as practitioners in international law.

Download or read book Adaptive Stream Mining written by Albert Bifet and published by IOS Press. This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.

Download or read book Signal Processing for Communications written by Paolo Prandoni and published by Collection Savoir suisse. This book was released on 2008-06-17 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.

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.
