Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de la thèse est de créer et développer de nouvelles méthodes de résolution efficaces des problèmes combinatoires en configuration des lignes de fabrication. Deux problèmes ont été particulièrement étudiés: le problème d'équilibrage et de choix d'équipement pour des lignes dédiées et le problème de minimisation des coûts de changements de séries pour des lignes multi-produits. Une solution du premier problème consiste en une affectation admissible des ressources à un nombre de stations à déterminer de sorte que le coût total soit minimal. Afin de résoudre ce problème, nous l'avons réduit au problème de partition d'ensemble et l'avons résolu par des heuristiques gloutonnes et une méthode exacte de génération de contraintes. Les expérimentations sur différentes instances ont montré que la nouvelle approche de résolution surclasse les approches antérieures de la littérature en termes de qualité de solution et de temps de calcul. Pour le second problème deux critères sont considérés lexicographiquement : la minimisation du nombre de stations et la minimisation du coût de changement de séries. Nous avons examiné successivement les cas d'exécution parallèle et séquentielle des opérations. Des solutions approchées ont été trouvées par des heuristiques gloutonnes. Ensuite, nous avons proposé deux modèles de programmation linéaire en nombres entiers (PLNE) afin de trouver le nombre de stations minimal et ensuite d'obtenir le coût de changement de séries minimal. Les résultats des expérimentations sur ces nouveaux problèmes se sont avérés prometteurs à la fois en termes de qualité de solution et de temps de calcul.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Actuellement, les fabricants sont soumis à une pression économique importante et à une concurrence internationale accrue due à la globalisation des marchés. Pour réussir, les fabricants doivent être capables de répondre rapidement aux changements de la demande en adaptant leurs systèmes de production. Cette adaptation aux changements peut être réalisée à travers multiples reconfigurations du système de production.Les travaux présentés dans ce mémoire portent sur l'élaboration des méthodes de recherche opérationnelle permettant d'accompagner le décideur lors de la reconfiguration d'une ligne de transfert ou d'assemblage. Ce problème apparaît lorsqu'un nouveau produit doit être fabriqué par une ligne existante ou lorsqu'il y a eu des changements dans les caractéristiques du produit. Par conséquent, il devient nécessaire de modifier la configuration du système de production tout en minimisant les coûts induits. Ces coûts sont évalués différemment pour les systèmes automatisésou manuels. Dans le premier cas, qui correspond au cas des lignes de transfert, pour limiter les investissements, il est souhaitable de réutiliser au maximum les équipements existants à condition que les contraintes techniques et technologiques soient respectées. Dans le cas des lignes manuelles qui sont représentées dans notre étude par les lignes d'assemblage, l'objectif est de minimiser les coûts liés à l'apprentissage des opérateurs causés par la réaffectation de leurs tâches.Les méthodes de résolution exactes basées sur la modélisation mathématique et la programmation linéaire en nombre mixtes ainsi qu'une méthode de type goal programming sont développées dans ce travail pour argumenter la prise de décisions lors de la reconfiguration des lignes de production. Les méthodes proposées ont été testées avec succès sur des échantillons de problèmes proches des cas industriels et ont montré leur efficacité.

Available in PDF, EPUB and Kindle. Book excerpt: Michel de Certeau considers the uses to which social representation and modes of social behavior are put by individuals and groups, describing the tactics available to the common man for reclaiming his own autonomy from the all-pervasive forces of commerce, politics, and culture. In exploring the public meaning of ingeniously defended private meanings, de Certeau draws on an immense theoretical literature in analytic philosophy, linguistics, sociology, semiology, and anthropology--to speak of an apposite use of imaginative literature.

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.

Download or read book The Random Cluster Model written by Geoffrey R. Grimmett and published by Springer Science & Business Media. This book was released on 2006-12-13 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The random-cluster model has emerged as a key tool in the mathematical study of ferromagnetism. It may be viewed as an extension of percolation to include Ising and Potts models, and its analysis is a mix of arguments from probability and geometry. The Random-Cluster Model contains accounts of the subcritical and supercritical phases, together with clear statements of important open problems. The book includes treatment of the first-order (discontinuous) phase transition.

Download or read book Theory of Finite and Infinite Graphs written by Denes König and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: To most graph theorists there are two outstanding landmarks in the history of their subject. One is Euler's solution of the Konigsberg Bridges Problem, dated 1736, and the other is the appearance of Denes Konig's textbook in 1936. "From Konigsberg to Konig's book" sings the poetess, "So runs the graphic tale . . . " 10]. There were earlier books that took note of graph theory. Veb len's Analysis Situs, published in 1931, is about general combinato rial topology. But its first two chapters, on "Linear graphs" and "Two-Dimensional Complexes," are almost exclusively concerned with the territory still explored by graph theorists. Rouse Ball's Mathematical Recreations and Essays told, usually without proofs, of the major graph-theoretical advances ofthe nineteenth century, of the Five Colour Theorem, of Petersen's Theorem on I-factors, and of Cayley's enumerations of trees. It was Rouse Ball's book that kindled my own graph-theoretical enthusiasm. The graph-theoretical papers of Hassler Whitney, published in 1931-1933, would have made an excellent textbook in English had they been collected and published as such. But the honour of presenting Graph Theory to the mathe matical world as a subject in its own right, with its own textbook, belongs to Denes Konig. Low was the prestige of Graph Theory in the Dirty Thirties. It is still remembered, with resentment now shading into amuse ment, how one mathematician scorned it as "The slums of Topol ogy.""

Download or read book Corpus written by Jean-Luc Nancy and published by Fordham Univ Press. This book was released on 2009-08-25 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: How have we thought “the body”? How can we think it anew? The body of mortal creatures, the body politic, the body of letters and of laws, the “mystical body of Christ”—all these (and others) are incorporated in the word Corpus, the title and topic of Jean-Luc Nancy’s masterwork. Corpus is a work of literary force at once phenomenological, sociological, theological, and philosophical in its multiple orientations and approaches. In thirty-six brief sections, Nancy offers us at once an encyclopedia and a polemical program—reviewing classical takes on the “corpus” from Plato, Aristotle, and Saint Paul to Descartes, Hegel, Husserl, and Freud, while demonstrating that the mutations (technological, biological, and political) of our own culture have given rise to the need for a new understanding of the body. He not only tells the story of this cultural change but also explores the promise and responsibilities that such a new understanding entails. The long-awaited English translation is a bold, bravura rendering. To the title essay are added five closely related recent pieces—including a commentary by Antonia Birnbaum—dedicated in large part to the legacy of the “mind-body problem” formulated by Descartes and the challenge it poses to rethinking the ancient problems of the corpus. The last and most poignant of these essays is “The Intruder,” Nancy’s philosophical meditation on his heart transplant. The book also serves as the opening move in Nancy’s larger project called “The deconstruction of Christianity.”

Download or read book Theory and Practice written by Jacques Derrida and published by University of Chicago Press. This book was released on 2019-01-31 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in paperback, nine lectures from Jacques Derrida that challenge the influential Marxist distinction between thinking and acting. Theory and Practice is a series of nine lectures that Jacques Derrida delivered at the École Normale Supérieure in 1976 and 1977. The topic of “theory and practice” was associated above all with Marxist discourse and particularly the influential interpretation of Marx by Louis Althusser. Derrida’s many questions to Althusser and other thinkers aim at unsettling the distinction between thinking and acting. Derrida’s investigations set out from Marx’s “Theses on Feuerbach,” in particular the eleventh thesis, which has often been taken as a mantra for the “end of philosophy,” to be brought about by Marxist practice. Derrida argues, however, that Althusser has no such end in view and that his discourse remains resolutely philosophical, even as it promotes the theory/practice pair as primary values. This seminar also draws fascinating connections between Marxist thought and Heidegger and features Derrida’s signature reconsideration of the dichotomy between doing and thinking. This text, available for the first time in English, shows that Derrida was doing important work on Marx long before Specters of Marx. As with the other volumes in this series, it gives readers an unparalleled glimpse into Derrida’s thinking at its best—spontaneous, unpredictable, and groundbreaking.

Download or read book Functional Integration written by Cécile Dewitt-Morette and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The program of the Institute covered several aspects of functional integration -from a robust mathematical foundation to many applications, heuristic and rigorous, in mathematics, physics, and chemistry. It included analytic and numerical computational techniques. One of the goals was to encourage cross-fertilization between these various aspects and disciplines. The first week was focused on quantum and classical systems with a finite number of degrees of freedom; the second week on field theories. During the first week the basic course, given by P. Cartier, was a presentation of a recent rigorous approach to functional integration which does not resort to discretization, nor to analytic continuation. It provides a definition of functional integrals simpler and more powerful than the original ones. Could this approach accommodate the works presented by the other lecturers? Although much remains to be done before answering "Yes," there seems to be no major obstacle along the road. The other courses taught during the first week presented: a) a solid introduction to functional numerical techniques (A. Sokal) and their applications to functional integrals encountered in chemistry (N. Makri). b) integrals based on Poisson processes and their applications to wave propagation (S. K. Foong), in particular a wave-restorer or wave-designer algorithm yielding the initial wave profile when one can only observe its distortion through a dissipative medium. c) the formulation of a quantum equivalence principle (H. Kleinert) which. given the flat space theory, yields a well-defined quantum theory in spaces with curvature and torsion.

Download or read book Deleuze Lucretius Encounter written by Ryan J. Johnson and published by Edinburgh University Press. This book was released on 2016-12-05 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than any other 20th-century philosopher, Deleuze considers himself an apprentice to the history of philosophy. But scholarship has ignored one of the more formative influences on Deleuze: Lucretian atomism. Deleuze's encounter with Lucretius sparked a way of thinking that resonates throughout all his writings: from immanent ontology to affirmative ethics, from dynamic materialism to the generation of thought itself. Filling a significant gap in Deleuze Studies, Ryan J. Johnson tells the story of the Deleuze-Lucretius encounter that begins and ends with a powerful claim: Lucretian atomism produced Deleuzianism.

Download or read book The Production of Space written by Henri Lefebvre and published by Wiley-Blackwell. This book was released on 1992-04-08 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Henri Lefebvre has considerable claims to be the greatest living philosopher. His work spans some sixty years and includes original work on a diverse range of subjects, from dialectical materialism to architecture, urbanism and the experience of everyday life. The Production of Space is his major philosophical work and its translation has been long awaited by scholars in many different fields. The book is a search for a reconciliation between mental space (the space of the philosophers) and real space (the physical and social spheres in which we all live). In the course of his exploration, Henri Lefebvre moves from metaphysical and ideological considerations of the meaning of space to its experience in the everyday life of home and city. He seeks, in other words, to bridge the gap between the realms of theory and practice, between the mental and the social, and between philosophy and reality. In doing so, he ranges through art, literature, architecture and economics, and further provides a powerful antidote to the sterile and obfuscatory methods and theories characteristic of much recent continental philosophy. This is a work of great vision and incisiveness. It is also characterized by its author's wit and by anecdote, as well as by a deftness of style which Donald Nicholson-Smith's sensitive translation precisely captures.

Download or read book Persistence Theory From Quiver Representations to Data Analysis written by Steve Y. Oudot and published by American Mathematical Soc.. This book was released on 2017-05-17 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistence theory emerged in the early 2000s as a new theory in the area of applied and computational topology. This book provides a broad and modern view of the subject, including its algebraic, topological, and algorithmic aspects. It also elaborates on applications in data analysis. The level of detail of the exposition has been set so as to keep a survey style, while providing sufficient insights into the proofs so the reader can understand the mechanisms at work. The book is organized into three parts. The first part is dedicated to the foundations of persistence and emphasizes its connection to quiver representation theory. The second part focuses on its connection to applications through a few selected topics. The third part provides perspectives for both the theory and its applications. The book can be used as a text for a course on applied topology or data analysis.
