It is an important step of the facility planning process where converge determinants from business strategy, economic and work factors, among others. The knowledge and techniques of this application area have evolved as the factory concept itself have changed and new aspects were considered as important ones. The traditional tools and techniques have considered just part of the aspects related to the layout, as proximity relationships and material flows. This work aimed to determine a formalism able to represent, in an integrated way, the aspects considered during the creation and evaluation of layout alternatives by multidisciplinary design teams. This formalism, based on objects and relationships, breaks with the prescriptive vision present in traditional facility layout software. The software that has been developed from the formalism presents an innovative way for layout designing, and points out to several other innovation opportunities. It is expected that this formalism may be used for developing software to support work activities of people involved with industrial facilities planning. / O arranjo físico é um fator importante dos sistemas de produção e constitui-se em uma etapa do projeto de instalações produtivas onde convergem determinantes da estratégia de negócios, fatores econômicos e de trabalho, entre outros. Os conhecimentos e técnicas dessa área de aplicação evoluíram na medida em que o próprio conceito de fábrica era alterado e novos aspectos passaram a ser considerados importantes. Tradicionalmente as ferramentas e técnicas desenvolvidas trataram geralmente de apenas um dos aspectos considerados no arranjo físico, como as relações de proximidade e de fluxo de materiais. O trabalho desenvolvido buscou determinar um formalismo capaz de representar de forma integrada os aspectos considerados durante a criação e avaliação de alternativas de arranjo físico por grupos multidisciplinares de projeto. Esse formalismo, baseado em objetos e relações, rompe com a visão prescritiva do uso de programas computacionais usados em projetos de arranjo físico. O programa computacional desenvolvido a partir do formalismo apresenta uma forma inovadora para projetar alternativas de layout, além de apontar várias outras oportunidades de inovação. Espera-se que o formalismo desenvolvido sirva de modelo para o desenvolvimento de outros programas computacionais desse tipo.

Approved for public release; distribution is unlimited / The contribution of this thesis is the development of a CAD (computer aided design) tool for current mode multiple-valued logic (MVL) CMOS circuits. It is only the second known MVL CAD tool and the first CAD tool for MVL CMOS. The tool accepts a specification of the function to be realized by the user, produces a minimal or near-minimal realization (if such a realization is possible), and produces a layout of a programmable logic array (PLA) integrated circuit that realizes the given function. The layout is in MAGIC format, suitable for submission to a chip manufacturer. The CAD tool also allows the user to simulate the realized function so that he/she can verify correctness of design. The CAD tool is designed also to be an analysis tool for heuristic minimization algorithms. As part of this thesis, a random function generator and statistics gathering package were developed. In the present tool, two heuristics are provided and the user can choose one or both. In the latter case, the better realization is output to the user. The CAD tool is designed to be flexible, so that future improvements can be made in the heuristic algorithms, as well as the layout generator. Thus, the tool can be used to accommodate new technologies, for example, a voltage mode CMOS PLA rather than the current mode CMOS currently implemented. / http://archive.org/details/cadtoolforcurren00leeh / Lieutenant, Republic of Korea Navy

The semestral project will focus on using Computer Aided Engineering for analysis of the ESEM differential chamber. The instruments used for the analysis, evaluation and scrutiny of the given issue will be the CAD and CAE systems (Computer Aided Design and Computer Aided Engineering).

This master's thesis deals with influence of the shape comparison of convergent and Laval nozzles in the secondary electron detector shutters to the resulting pressure and gas flow in the secondary electron detector for environmental scaning electron mictoscope. To the detector analysis are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.

The aim of this project is using the CAE system to analyze the distribution of the temperature profile brazing furnace DIMA 0180. To create the model is used SolidWorks Premium 2012. The simulation is performed using the Flow Simulation. This work builds on the knowledge diploma thesis by Martin Procházka titled The effect of different heat capacities and components on the longitudinal temperature profile for reflow soldering. We start from the knowledge of heat transfer, especially of heat conduction and radiation, which appear in the furnace.
