Available in PDF, EPUB and Kindle. Book excerpt: La plupart des travaux en ordonnancement repose sur un modèle déterministe, peu adapté à la réalité de l'ordonnancement d'atelier. En effet, les ateliers de production sont soumis à un certain nombre 'incertitudes. C'est pourquoi l'ordonnancement sous incertitudes est un domaine en pleine expansion. D'autre part, l'humain n'est généralement pas pris en compte dans l'élaboration de la méthode d'ordonnancement. Pourtant, l'humain joue un rôle central dans le processus d'ordonnancement, et ses connaissances du terrain sont précieuses. C'est pourquoi nous pensons que des systèmes homme-machine efficaces sont nécessaires au bon fonctionnement des méthodes d'ordonnancement d'atelier. Pour cela, nous nous reposons sur l'ordonnancement de groupes. Cetteméthode d'ordonnancement d'atelier comporte différents avantages pour notre recherche : c'est une méthode d'ordonnancement sous incertitudes et sa structure est facilement manipulable par l'humain. Nous étudions les systèmes homme-machine existant pour cette méthode d'ordonnancement. Nous proposons ensuite de nouveaux systèmes homme-machine, afin d'améliorer la coopération. Dans ces systèmes, nous utilisons la qualité dans le meilleur des cas dans un ordonnancement de groupes. Comme ce thème n'est pas encore abordé dans la littérature, nous proposons des bornes inférieures, des heuristiques et une méthode exacte pour résoudre ce problème

Download or read book FiWi Access Networks written by Martin Maier and published by Cambridge University Press. This book was released on 2011-12-15 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of broadband access networks toward bimodal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. After discussing the economic impact of broadband access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are reviewed. State-of-the-art GPON and EPON fiber access networks are described, including their migration to next-generation systems such as OCDMA and OFDMA PONs. The latest developments of wireless access networks are covered, including VHT WLAN, Gigabit WiMAX, LTE and WMN. The advantages of FiWi access networks are demonstrated by applying powerful network coding, heterogeneous optical and wireless protection, hierarchical frame aggregation, hybrid routing and QoS continuity techniques across the optical-wireless interface. The book is an essential reference for anyone working on optical fiber access networks, wireless access networks or converged FiWi systems.

Download or read book Food Industry Studies written by United States. Congress. Senate. Select Committee on Nutrition and Human Needs and published by . This book was released on 1976 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A report of a US congressional subcommittee focuses on the assessment of food industry cost data price factors for evaluating the issue of rapidly rising consumer food prices. The report includes a series of federal questionnaires that were developed for this assessment, which, due to the reluctance of the largest food industry firms to provide a variety of fiscal data (e.g., direct and indirect costs, income, taxes) are largely published without the requested data. The report also provides information concerning: a preliminary assessment of USDA's farm-to-retail price spreads for a variety of foods (beef, pork, bread, dairy products); an assessment of price margins in the beef industry; and the economic organization of the milling and bread industry. The legal and public justifications for conducting these studies are detailed. Extensive tabular data are presented on the fiscal and quantitative dimensions of the food industry, including acquisition and production activities, processing, wholesaling, and retailing.

Download or read book Democracy Challenged written by Marina Ottaway and published by Carnegie Endowment. This book was released on 2013-01-25 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1990s, international democracy promotion efforts led to the establishment of numerous regimes that cannot be easily classified as either authoritarian or democratic. They display characteristics of each, in short they are semi-authoritarian regimes. These regimes pose a considerable challenge to U.S. policymakers because the superficial stability of many semi-authoritarian regimes usually masks severe problems that need to be solved lest they lead to a future crisis. Additionally, these regimes call into question some of the ideas about democratic transitions that underpin the democracy promotion strategies of the United States and other Western countries. Despite their growing importance, semi-authoritarian regimes have not received systematic attention. Marina Ottaway examines five countries (Egypt, Azerbaijan, Venezuela, Croatia, and Senegal) which highlight the distinctive features of semi-authoritarianism and the special challenge each poses to policymakers. She explains why the dominant approach to democracy promotion isn't effective in these countries and concludes by suggesting alternative policies. Marina Ottaway is senior associate and codirector of the Democracy and Rule of Law Project at the Carnegie Endowment.
