iNET System Operational FlowsGrace, Thomas B., Abbott, Ben A., Moodie, Myron L. 10 1900 (has links)
ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, California / The integrated Network-Enhanced Telemetry (iNET) project is transitioning from standards development to deployment of systems. In fielding a Telemetry Network System (TmNS) demonstration system, one must choose and integrate technological building blocks from the suite of standards to implement new test capabilities. This paper describes the operation of a TmNS and identifies the management, configuration, control, acquisition, and distribution of information and operational flows. These items are discussed utilizing a notional system to walk through the mechanisms identified by the iNET standards. Note that at the time of this paper the efforts discussed are only at the very beginning of the design process and will likely evolve throughout the design process.

Diretrizes para a elaboração de um modelo de gestão dos fluxos de informações como suporte à logística em empresas construtoras de edifícios. / Guidelines for elaborating an information flow model as a support to the logistics in building construction firms.Villagarcia Zegarra, Sofia Lilianne 19 December 2000 (has links)
Este trabalho objetiva propor diretrizes para a elaboração de um modelo de gestão de fluxo de informações como suporte à logística em empresas construtoras de edifícios. O foco da pesquisa limita-se especificamente à gestão de materiais, apesar da logística também abranger mão-de-obra, serviços e equipamentos. O objetivo da gestão de materiais é o de assegurar um fluxo continuo e sem interferências de materiais e componentes à obra, na quantidade requerida, com a qualidade especificada, no tempo e lugar certo, ao menor custo total. Estas diretrizes foram identificadas visando a uma integração funcional dentro da empresa construtora. Com base em um estudo de caso realizado em três empresas construtoras e em um levantamento e estudo bibliográfico, foram estudados os fluxos de informações ligados à gestão de materiais que ocorrem dentro das empresas construtoras. Desta maneira, identificaram-se os principais fatores que facilitam e que dificultam os fluxos de informações entre agentes relacionados com a gestão de materiais. Uma vez analisados estes fatores, foram identificadas as diretrizes objeto desta pesquisa e foi proposto um fluxo de informações modelo baseado exclusivamente nos casos estudados. Adicionalmente, foram discutidos alguns parâmetros a se levar em conta para avaliar o modelo proposto e conseguir uma melhoria continua dentro do processo. Também, foi brevemente discutida a forma como as parcerias com os fornecedores, o uso de produtos normalizados, a Internet e os códigos de barras poderiam inovar estes fluxos de informações e conseguir a integração tão almejada na cadeia de suprimentos. / This research aims to identify guidelines for developing an information flow management model to support materials management in building construction firms. The main purpose of building materials management is to have the required materials at the right place, at the right time, in the right quantity without prejudicing cost and quality. These guidelines were identified considering a functional integration within the construction firm. Based on three case studies developed in construction firms and a literature review, the materials management information flows inside the construction firm were studied. In this way, the principal factors that affect or enhance these information flows were analyzed. Once analyzed these factors, we were able to determine the best arrange for these flows and identify the guidelines and propose an information flow model based exclusively in the three cases studied. Besides this, we discussed the parameters that should be taken into account to guarantee a continuous improvement in the model proposed. Finally, we briefly discuss how partnering with suppliers, the use of normalized products, the Internet and the use of code bars could innovate traditional information flows and integrate the supply chain.

Dependency-based collaborative design: a comparison of modeling methodsDrabble, Brian 19 March 2015 (has links)
No / The ability to provide support to a group of designers, analysts and other users who are collaborating on an evolving design requires the dual capabilities of managing options for an individual designer while at the same time managing the dependencies between different sets of designer's options. For example, if designer A is creating a design for a helicopters hydraulics system and this is dependent on electrical power (EP) from a sub-system from designer B then how can the workflows, decisions and options of the two designers be managed so that each can understand the implications of their own design decisions and more importantly the implications and design decisions they force on others? The proposed CAPS system employs two dependency reasoning engines: one handles quantitative values and other qualitative ones. The quantitative engine can identify that a motor with an output of 3000 rpm allows a generator to output 100 V or that a hydraulic pump is dependent on the 240v output of the motor. Alternatively, the qualitative engine could rule out several motors options if the overall design state that the weight of a helicopter's transmission needs to be comparable to that of the engine or the positioning of a sensor makes it susceptible to an EM process that could affect its function. A mapping capability is provided allowing analysis to be passed between the two engines. Three different types of dependency-based quantitative engine designs have been developed and evaluated. The first quantitative engine design focuses on modeling components at their output level and propagating level values from component to component, component to sub-system, etc. The second quantitative engine design focuses on modeling components at the node level so as to identify key components, sub-systems, etc. in terms of their overall dependency to the design. The third engine employs a hybrid of the previous two approaches and was identified through feedback from designers. These engines are designed to be complimentary with the node-based and hybrid approaches being used to identify the key capabilities and dependencies of the design. The output-based approach is then used to explore in greater detail the outputs and dependencies of the components and sub-systems identified as key via the node/hybrid-based approach. The proposed CAPS architecture has been initially evaluated against a large collaborative design task involving the design of a helicopter's electrical, hydraulic, structural and mechanical systems.

Beyond IT and Productivity : Effects of Digitized Information Flows in Grocery DistributionHorzella, Åsa January 2005 (has links)
During the last decades organizations have made large investments in Information Technology (IT). The effects of these investments have been studied in business and academic communities over the years. A large amount of research has been conducted on the relation between the investments in IT and productivity growth. Productivity is a central measure of national and organizational success and is often considered in economic decisionmaking. Researchers have however found it difficult to present a clear-cut answer to the effect of IT investments on productivity growth; an inability defined as the productivity paradox. Within the Impact of IT on Productivity (ITOP) research program the relevance of the productivity measure as an indicator of the value of IT is questionned. IT has over the years replaced physical interfaces with digital and in this way enabled new ways to process information. A retrospective research approach is therefore applied where the effects of digitized information flows are studied within specific organizational settings. In this thesis the effects of digitized information flows within Swedish grocery distribution are studied. A comprehensive presentation of the development is first conducted and three focal areas are thereafter presented. These describe supply chain information flows including order information, information on new items and analysis of point-of-sales information. The presentation of the focal areas identifies a number of effects from the digitization of information flows. The effects are analyzed according to a predefined analytical framework. The effects are divided into five categories and are thereafter evaluated when it comes to potential for generating value. The study shows that the digitization of information flows has generated numerous, multifaceted effects. Automational, informational, transformational, consumer surplus and other effects are observed. They are difficult to evaluate using a single ndicator. Specific indicators that are closely related to the effects can however be defined. The study also concludes that the productivity measure does not capture all positive effects generated by digitized information flows. / <p>ISRN/Report code: LiU-Tek-Lic-2005:39</p>

Globální digitální propast a změny v informačních tocích / The global digital divide and the changing information flowsMelicharová, Eliška January 2019 (has links)
The thesis deals with the global information flows and its aim is to find factors which influence them. Firstly, the visibility of the country in international news is explored, i.e. which countries are dominantly represented in the international news. Secondly, the exposure of the country towards international news is observed, i.e how countries vary in the openness towards the international news. The thesis also seek to reveal factors which have an impact on the visibility of the country and on the exposure. The thesis consists of a recherche part with the theory of globalization and a quantitative analysis based on the dataset from 2014-2017. The thesis concludes that countries are represented unevenly with few dominant countries (the most dominant country is China, followed by USA and Ukraine) in the international news and that the most exposed countries have been found small developing countries (Saint Lucia, Antigua and Barbuda, etc.) from South America. Regarding the factors of visibility of the country, the highest impact has the size of population,and also GNI and the presence of violent correlated. On the contrary, all factors impacting the exposure of the country were found statistically insignificant.
