Design and operation of flexible manufacturing networks
Get PDFOne of the most identifiable trends in the fundamental changes that are currently transforming manufacturing industry is the vertical and horizontal integrated value-chain. While some companies are pursuing subcontracting to allow them to concentrate on their customers and core competencies, others are building their businesses by focusing on these out-sourced tasks. Original Equipment Manufacturers (OEMs) are evolving into total solution providers. OME is a company that uses product components from one or more other companies to build a product and delivers it to the customer under its own company name or brand.Collaborations between these two groups are the emergence of Flexible Manufacturing Networks (FMNs) that strongly challenge existing business models and the traditional manufacturing concepts. FMNs have more access to outside information and market contacts, and use both personal contacts and modern communication tools to maintain contacts and information flow. In addition, FMNs develop internal mechanisms needed to ensure cooperation, pooling of information, collective learning, and access to specialized services from local and outside suppliers.Through firms' cooperation, firms gain access to markets or equipment that would have to had otherwise no access to them, or are able to achieve lower costs than they could on their own. But competition is always present, even among the firms in the network: a firm may choose to work with one firm on one network and with second firm on anther network, depending on which combination seems more likely to succeed at a particular job. FMNs are created to take advantage of market opportunities for particular products in what are often rapidly changing market niches. When market conditions change, FMNs disband and organize in different forms to take advantage of new opportunities.This thesis seeks to explore the new phenomenon of inter-firm collaborations and to understand in more detail the design and operation of FMNs. It elaborates a conceptual framework for the FMN that consists of manufacturing, storage, transportation and service companies. The FMN is also recognized as an organizational basis for future manufacturing.The objective is to deliver the order at a minimal cost within the delivery time allowed by the customer or market. This thesis presents furthermore an approach to the design and operation of the FMNs through the appropriate selection of partners, and also coordinates the tasks among these partners. Therefore, the objectives of the thesis are to:Define the global manufacturing environment and its impact on the manufacturers, Define FMN goals, Cite FMNs design and operation, Establish a configuration and coordination approach for the most appropriate selection of the manufacturing partners, Plan the tasks among the partners for a specific customer's orders.Einer der stärksten Trends in der Fertigungsindustrie ist die vertikale und horizontale Integration der Werteketten. Während bestimmte Firmen viele Aufgaben auslagern um sich auf ihre Kunden und Kernkompetenzen zu konzentrieren, bilden diese "outgesourceten" Aufgaben die Basis des Geschäftes anderer Unternehmen. Sogenannte "Original Equipment Manufacturers" (OEMs) entwickeln sich zu Lieferanten von Gesamtlösungen. Ein OEM ist eine Firma, die Produktbestandteile von einem oder mehren Firmen kombiniert, um ein Produkt zu erstellen und es an den Kunden unter seinem eigenen Firmennamen oder einer anderen Marke zu vertreiben. Diese Zusammenarbeit zwischen diesen beiden Gruppen wird "Flexible Manufacturing Networks" (FMNs) bezeichnet und stellt eine große Herausforderung für vorhandene Geschäftsmodelle und traditionelle Fertigungskonzepte dar. FMNs haben besseren Zugang zu Informationen von außen und Marktkontakten, dabei benutzen sie sowohl persönliche Beziehungen als auch moderne Kommunikationswerkzeuge, um den Informationsfluss sicherzustellen. Zusätzlich entwickeln FMNs Mechanismen um Zusammenarbeit zu sichern, Informationen zu poolen, das kollektive Lernen und den Zugang zu fachspezifischen Serviceleistungen von lokalen und weiter entfernten Lieferanten sicherzustellen.Durch Kooperation können die Unternehmen Zutritt zu Märkten oder bestimmten Infrastruktureinrichtungen erlangen, welche ihnen sonst insgesamt verschlossen bleiben würden und oftmals Kostenreduktionen erreichen die jeder einzelnen Firma nicht möglich wäre. Die Konkurrenz zwischen den Unternehmen ist aber immer existent, auch zwischen den Mitgliedern im Netzwerk: Ein Unternehmen kann beschließen, mit einem bestimmten Unternehmen in einem Netzwerk und mit einem zweitem Unternehmen in einem anderem Netzwerk zusammenzuarbeiten, um einen bestimmten Auftrag zu erlangen. FMNs entstehen oftmals um Nutzen aus sich häufig ändernden Marktsituationen für bestimmte Produkte zu ziehen.Wenn sich die Marktlage ändert, lösen sich bestimmte FMNs auf und organisieren sich in unterschiedlichen Formen neu, um geänderte Markchancen zu nutzen.Diese Dissertation versucht, das neue Phänomen der interorganisationalen Kooperation zu erforschen und die Gestaltung und das Funktionieren von FMNs besser zu verstehen. Sie erarbeitet einen konzeptionellen Rahmen für FMNs, bestehend aus Produktions-, Lagerungs- und Transportunternehmen. FMN ist auch eine neue organisatorische Grundlage für zukünftige Produktion.Die Zielsetzung ist es, den Auftrag zu minimalen Kosten innerhalb der Lieferfrist zu liefern, die durch den Kunden oder den Markt gefordert wird. Diese Dissertation stellt ausserdem einen Ansatz für das Design und das Betreiben von FMNs durch die passende Auswahl der Partner sowie die Koordinierung der Aufgaben zwischen diesen Partnern, dar. Die Zielsetzungen der Dissertation sind daher folgende: Definition des globalen Umfeldes von Produktionsunternehmen und deren Auswirkungen, Definition der Ziele von FMNs, Entwicklung eines Rahmens für Design und Betrieb von FMNs, Erstellung eines Ansatzes zur Konfiguration und Koordination von FMNs sowie für die Auswahl von Netzwerk Partnern, und Planung der Aufgaben zwischen Partnern für spezifische Kundenaufträge
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
