This book was released on 2012-07 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans plusieurs secteurs d'activites industrielles comme la siderurgie, la metallurgie ou l'industrie de la ceramique le systeme de production contient toujours une machine dite goulot d'etranglement par laquelle passe la majorite, voire la totalite des commandes dans plusieurs des cas. La gestion de cette machine est cruciale pour l'entreprise, car elle est responsable des retards dans la livraison des commandes aux clients. Nous proposons dans cette these plusieurs approches de resolution efficaces pour le probleme d'une machine unique avec temps de reglages dependants de la sequence dans le but de minimiser le retard total. Nous presentons, d'abord, un algorithme genetique dote d'un nouvel operateur de croisement qui se veut plus performant que les operateurs de croisement classique de la litterature. Nous explorons ensuite la conception d'algorithmes genetiques hybrides ameliorant le processus d'intensification de l'algorithme propose en integrant une methode exacte et des mecanismes appartenant a d'autres methodes de resolution afin d'en ameliorer la performance. Ce livre cible tous les chercheurs en optimisation combinatoire travaillant sur les methodes hybrides.

This book was released on 2009 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Améliorer la coordination et la planification de la production vis-à-vis des activités logistiques des ateliers de production réel (à savoir les ressources : machines et engins de transport) est devenu une grande nécessité pour la diminution des coûts et la réduction des délais de livraison. La présente thèse est scindée en quatre parties. La première partie est un tour d’horizon des problèmes d’ordonnancement, l’accent est mis essentiellement sur les environnements Job Shop. Dans la deuxième partie, nous présentons une étude plus détaillée de ces environnements :problématique, état de l’art, modélisation et méthodes de résolution. Dans le cadre de la logistique interne des ateliers de production de type Job Shop, nous étudions dans la troisième partie, deux problématiques, le Job Shop avec transport dans un environnement ‘’juste à temps’’ et le Job Shop à flexibilité partielle avec maintenance préventive. La dernière partie est consacrée au problème d’atterrissage d’avions multipistes que nous avons modélisé sous forme de problème de Job Shop. Dans les différents cas d’études présentés, notre travail s’articule autour d’une étude systématique à base de trois fondamentaux, une formulation mathématique et/ou graphique du problème puis une résolution par une approche d'optimisation à base de métaheuristiques hybrides et enfin une validation des résultats par des simulations numériques. Notre objectif était de développer des systèmes d’ordonnancement dynamique d’aide à la décision capables de supporter la nature NP-complet des problèmes étudiés.

Available in PDF, EPUB and Kindle. Book excerpt: L'accroissement des profits, à travers l'amélioration de la productivité et la réduction des pertes de matières, représente un objectif primordial pour les entreprises industrielles. Dans cette thèse, nous nous intéressons à la résolution d'un problème industriel complexe réel avec des contraintes de temps. Nous nous sommes intéressés, tout d'abord, à un objectif principal, soit la minimisation des dates de fin de production, suivi d'un objectif secondaire qui est la minimisation des quantités de déchets non recyclables. Dans un premier temps, nous avons modéliséle problème par des modèles mathématiques, que nous avons résolu à l'aide d'un solveur. Dans un second temps, nous avons proposé une méthode approchée en forme d'algorithmes évolutionnistes. Cette méthode est appliquée aux deux objectifs mentionnés ci-dessus séparément. Une troisième méthode est ensuite appliquée à l'objectif principal, à savoir une méthode arborescente approchée. Nous avons testé les algorithmes proposés sur des instances inspirées d'un cas réel ; issues d'une entreprise du secteur agroalimentaire et sur des instances inspirées de la littérature.

Download or read book Multiple Criteria Optimization written by Xavier Gandibleux and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generalized area of multiple criteria decision making (MCDM) can be defined as the body of methods and procedures by which the concern for multiple conflicting criteria can be formally incorporated into the analytical process. MCDM consists mostly of two branches, multiple criteria optimization and multi-criteria decision analysis (MCDA). While MCDA is typically concerned with multiple criteria problems that have a small number of alternatives often in an environment of uncertainty (location of an airport, type of drug rehabilitation program), multiple criteria optimization is typically directed at problems formulated within a mathematical programming framework, but with a stack of objectives instead of just one (river basin management, engineering component design, product distribution). It is about the most modern treatment of multiple criteria optimization that this book is concerned. I look at this book as a nicely organized and well-rounded presentation of what I view as ”new wave” topics in multiple criteria optimization. Looking back to the origins of MCDM, most people agree that it was not until about the early 1970s that multiple criteria optimization c- gealed as a field. At this time, and for about the following fifteen years, the focus was on theories of multiple objective linear programming that subsume conventional (single criterion) linear programming, algorithms for characterizing the efficient set, theoretical vector-maximum dev- opments, and interactive procedures.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.

Download or read book Decentralised Internet of Things written by Mohammad Ayoub Khan and published by Springer. This book was released on 2020-02-14 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents practical as well as conceptual insights into the latest trends, tools, techniques and methodologies of blockchains for the Internet of Things. The decentralised Internet of Things (IoT) not only reduces infrastructure costs, but also provides a standardised peer-to-peer communication model for billions of transactions. However, there are significant security challenges associated with peer-to-peer communication. The decentralised concept of blockchain technology ensures transparent interactions between different parties, which are more secure and reliable thanks to distributed ledger and proof-of-work consensus algorithms. Blockchains allow trustless, peer-to-peer communication and have already proven their worth in the world of financial services. The blockchain can be implanted in IoT systems to deal with the issues of scale, trustworthiness and decentralisation, allowing billions of devices to share the same network without the need for additional resources. This book discusses the latest tools and methodology and concepts in the decentralised Internet of Things. Each chapter presents an in-depth investigation of the potential of blockchains in the Internet of Things, addressing the state-of-the-art in and future perspectives of the decentralised Internet of Things. Further, industry experts, researchers and academicians share their ideas and experiences relating to frontier technologies, breakthrough and innovative solutions and applications.

Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.
