Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur la modélisation et la résolution de différents problèmes intégrés d'ordonnancement et de transport. Ces problèmes demandent, entre autre, une coordination entre des activités/opérations de production, qui se définissent par une date de début et une durée, et des opérations de transport, qui se définissent par une date de début, une date de fin et une quantité transportée. Pour résoudre ces problèmes, plusieurs méthodes d'optimisation de type métaheuristique sont proposées, afin d'obtenir des solutions de bonne qualité dans des temps raisonnables. Trois problèmes intégrés sont traités successivement : 1) un problème d'ordonnancement à une machine avec un problème de transport limité à un seul véhicule ; 2) un problème d'ordonnancement à une machine avec un problème de transport à plusieurs véhicules ; 3) un problème d'ordonnancement de type RCPSP avec une flotte hétérogène de véhicules, permettant le transport des ressources entre les activités. Le premier problème est un problème d'ordonnancement/transport de type PTSP (Production and Transportation Scheduling Problem - PTSP), limité à un seul véhicule, présenté en 2008 par Geismar et al.. Une méthode de résolution de type GRASP×ELS est proposée dans le chapitre 2, les résultats obtenus avec cette méthode sont comparés aux meilleurs résultats de la littérature. Cette méthode est étendue dans le chapitre 3, afin de traiter du problème de PTPSP, avec une flotte homogène de véhicules. La méthode proposée possède un champ d'application plus large que la méthode de Geimar et al., dédiée au PTSP avec un véhicule, mais permet de résoudre efficacement le cas à un véhicule. Le dernier problème traité concerne la résolution d'un RCPSP, dans lequel une flotte de véhicules assure le transport d'une ressource d'une activité à l'autre. L'objectif est d'offrir une approche tirant profit de décisions stratégiques (organiser des échanges - flot - entre des sites), pour déterminer un plan de transport. La difficulté principale consiste à utiliser le flot, pour déterminer les opérations de transport (création de lots), afin de résoudre le problème d'affectation des véhicules, pour finalement ordonnancer les opérations de transport. Sur ce problème, une méthode heuristique de transformation est présentée dans le chapitre 4, ainsi qu'une méthode exacte (basée sur un algorithme de plus court chemin à contraintes de ressources) dans le chapitre 5.
Download or read book Essays and Surveys in Global Optimization written by Charles Audet and published by Springer Science & Business Media. This book was released on 2005-12-05 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global optimization aims at solving the most general problems of deterministic mathematical programming: to find the global optimum of a nonlinear, nonconvex, multivariate function of continuous and/or integer variables subject to constraints which may be themselves nonlinear and nonconvex. In addition, once the solutions are found, proof of its optimality is also expected from this methodology. Therefore, with these difficulties in mind, global optimization is becoming an increasingly powerful and important methodology. Essays and Surveys in Global Optimization is the most recent examination of its mathematical capability, power, and wide ranging solutions to many fields in the applied sciences.

Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Download or read book Formal Methods Applied to Complex Systems written by Jean-Louis Boulanger and published by John Wiley & Sons. This book was released on 2014-07-22 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents real-world examples of formal techniques in an industrial context. It covers formal methods such as SCADE and/or the B Method, in various fields such as railways, aeronautics, and the automotive industry. The purpose of this book is to present a summary of experience on the use of “formal methods” (based on formal techniques such as proof, abstract interpretation and model-checking) in industrial examples of complex systems, based on the experience of people currently involved in the creation and assessment of safety critical system software. The involvement of people from within the industry allows the authors to avoid the usual confidentiality problems which can arise and thus enables them to supply new useful information (photos, architecture plans, real examples, etc.).

Download or read book Automatic Text Summarization written by Juan-Manuel Torres-Moreno and published by John Wiley & Sons. This book was released on 2014-11-10 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Textual information in the form of digital documents quickly accumulates to create huge amounts of data. The majority of these documents are unstructured: it is unrestricted text and has not been organized into traditional databases. Processing documents is therefore a perfunctory task, mostly due to a lack of standards. It has thus become extremely difficult to implement automatic text analysis tasks. Automatic Text Summarization (ATS), by condensing the text while maintaining relevant information, can help to process this ever-increasing, difficult-to-handle, mass of information. This book examines the motivations and different algorithms for ATS. The author presents the recent state of the art before describing the main problems of ATS, as well as the difficulties and solutions provided by the community. The book provides recent advances in ATS, as well as current applications and trends. The approaches are statistical, linguistic and symbolic. Several examples are also included in order to clarify the theoretical concepts.

Download or read book The Political Economy of Populism written by Petar Stankov and published by Routledge. This book was released on 2020-07-21 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Political Economy of Populism explores the interplay between identity, the economy and inequality to explain the dynamics of populist votes since the beginning of the 20th century. The book discusses the political and economic implications of populist governance using data on populist incumbencies and linking it to historical data on the macro economy and democracy. Chapters draw from the most recent political science, economics and other social science literature, as well as historical data, to explain the long-term causes and consequences of populism. Populism emerges and gains traction when political entrepreneurs exploit underlying identity conflicts for political gains. As the distributional consequences of both economic distress and economic growth typically favor the elite over the poor and the lower middle class, economic shocks usually sharpen the underlying identity conflicts between the groups. The book provides evidence of significant differences in the ways fiscal and monetary policies are conducted by incumbent populists in Latin America, Europe and the OECD. The work concludes by suggesting avenues through which a 21st century social consensus can be built, so that our society can avoid repeating the mistakes that led to wars and failed economic experiments in the 20th century. The Political Economy of Populism marks a significant contribution to the study of populism and is suited to students and scholars across the social sciences, including economics, political science and sociology.
