A pesquisa foi realizada com usuários de cadeira de rodas e, por meio de questionários abertos e fechados, e análises qualitativas e quantitativas dos dados obtidos, foram levantadas as principais necessidades dos cadeirantes em relação à cadeira de rodas. As necessidades levantadas foram divididas em parâmetros, traduzidas em requisitos de engenharia e inseridas na Matriz I (Casa da Qualidade) do QFD. Os processos adotados são sugeridos para equipes com profissionais de diversas áreas, como metodologia válida, para levantamento da Voz do Cliente. A Matriz construída possibilitará estabelecer alguns requisitos para soluções possíveis de projeto de cadeira de rodas / Abstract: This work aimed to utilize instruments, techniques and procedures of the psychology science to help in the translation the basic necessities of the clients in a well arranged form, known as client voice, in order to aid in the application of the Quality Function Deployment(QFD). The research was carried out with Wheel chair users and utilizing both open and closed questionnaires and both qualitative and quantitative analysis of the obtained data, the main client necessities was raised in regard to the Wheel chairs. The necessities raised was divided in parameters which were translated in requisites of engineering and then inserted in the Matrix (House of the Quality) of the QFD. The processes taken as basis are suggested to teams with Professionals from several areas, as a valid methodology to survey the client voice. The generated Matrix will enable to establish some requisite to possible solutions of wheel chairs projects / Mestrado / Mecanica dos Sólidos e Projeto Mecanico / Mestre em Engenharia Mecânica

Prozessintegrierte Dokumentation und optimierte Wiederverwendung von Simulationsmodellen der automobilen Funktionsabsicherung / Process-integrated documentation and optimized reuse of simulation models of the automotive function safeguardingGruber, Thomas 26 September 2016 (has links) (PDF)
Die Schaffung, Wahrung und Nutzung von Wissen stellt heute eine wichtige Säule für die Konkurrenzfähigkeit von Unternehmen am Markt dar. Vor diesem Hintergrund steht insbesondere die moderne Funktionsentwicklung der Automobilindustrie vor der Herausforderung immer neue, hochgradig vernetzte Fahrzeugfunktionen zu entwickeln und in immer kürzerer Zeit und immer geringeren Kosten in den Markt zu bringen.
Um dieser Herausforderung gerecht zu werden, hat sich die modellbasierte Entwicklung mit dem Ziel der Beherrschung dieser steigenden Komplexität etabliert. Dadurch ist es möglich die Entwicklungsaufgaben auf unterschiedlichen Ebenen zu abstrahieren und eine verteilte, vernetzte Entwicklung zu realisieren. Die Entwicklung einer einzigen Funktion benötigt heute häufig mehrere hundert Personen, die in einen gemeinsamen Entwicklungsprozess integriert werden müssen. Hier fehlt es an Konzepten um den Informations- und Wissensfluss zwischen den Prozessbeteiligten sicherzustellen.
In diesem Kontext entwickelt die vorliegende Arbeit einen Ansatz zur prozessintegrierten Dokumentation der in modellbasierten Entwicklungsprozessen benötigten Entwicklungsartefakte. Der Ansatz betrachtet dabei den vollständigen Informationsfluss, von der Definition benötigter Informationen, über deren automatisierte Erfassung und Verarbeitung bis zur zielgerichteten Wiederverwendung.
Anschließend skizziert die Arbeit die Architektur eines Informationssystems, dass diese Durchgängigkeit in beliebigen, modellbasierten Entwicklungsprozessen ermöglicht und überträgt diese zur Validierung des Ansatzes auf einen konkreten Entwicklungsprozess der automobilen Funktionsentwicklung.
Der Fokus des Ansatzes liegt dabei insbesondere auf der Integration in bestehende Entwicklungsprozesse, ohne in diese verändernd einzugreifen. Dies wird einerseits durch eine modellbasierte Beschreibung des Informationsmodells, mit Methoden wie sie im Funktionsentwicklungsprozess Anwendung finden, erreicht. Prozessbeteiligte können dadurch das Informationsmodell selbst verstehen und bei Bedarf Anpassungen vornehmen, ohne auf geschulte Experten angewiesen zu sein. Andererseits erlaubt der architektonische Ansatz einen direkten Zugriff auf bestehende Entwicklungssysteme und darin enthaltenen dokumentationsrelevanten Informationen. / Today, the creation, preservation and exploitation of knowledge represent key factors of the competitiveness of companies in the global market. In this context, the modern function development in the automotive industry faces challenges to bring new, highly interconnected vehicle functions at shorter time and lower cost to the market.
To meet these challenges and manage the growing compelity, a model-based development process has been established. Thus, it is possible to distribute development tasks to different levels of abstraction and enable a distributed, interconnected function development.This development involves up to several hundred persons per function, who have to be integrated in a common development process. Especially when it comes to managing the information and knowledge flow between the process participants, there is a lack of concepts to support this communication.
Based on this context, this work presents an approach for process integrated documentation of the necessary development artifacts in model-based development processes. This approach considers the complete information flow, from the definition of necessary information, over automatic acquisition and processing to its targeted reuse during the process.
Subsequently, this work sketches the architecture of an information system, which enables this continuous approach to be applied to any model-based development process. For validation purposes, the approach is then applied to an actual development process of the automotive function development.
The focus of the presented approach lies in the integration in existing development processes without changing them. On the one hand, this is achieved by applying a model-based description of the information model using methods, that can be found in the function development process today. Thus, process participants can understand the information model themselves and apply changes when they are required without the necessity of qualified experts. On the other hand, the architectural approach allows a direct access to existing development systems and documentation relevant information they contain.

Previous issue date: 2004 / Resumo: No cenário atual, para serem competitivas, as empresas enfrentam o desafio de desenvolverem novos produtos em um espaço curto de tempo, com tecnologia superior à anterior e com custos reduzidos para garantir a sobrevivência do negócio. E o sucesso está diretamente atrelado aos requisitos exigidos pelos clientes, onde Qualidade, Confiabilidade, Entrega e Preço são o mínimo que se espera. Neste trabalho são abordadas metodologias utilizadas para o Planejamento e Garantia da Qualidade, as quais devem ser utilizadas já na fase de concepção do projeto do produto, pois é aqui que nasce em grande parte a qualidade, a confiabilidade e o preço
final do produto. O produto escolhido para análise se trata da Embreagem Automotiva e, como método proposto, fez-se primeiramente uma interação entre o Modelo de Kano juntamente com o QFD, Custeio Alvo e Análise de Valor, a fim de se avaliar o grau de atendimento aos requisitos do cliente e determinar quais as funções cujos custos relativos estão acima das necessidades relativas, oferecendo, portanto, potencial para otimização ou mesmo eliminação. Tem-se, em seguida, a construção da Árvore de Falhas (FTA) para identificação dos componentes críticos que oferecem maior risco de falha no sistema. O trabalho tem por objetivo final, a análise de
Confiabilidade e Regressão dos resultados obtidos nos ensaios, para determinação da confiabilidade da embreagem em estudo, componentes a serem melhorados ou otimizados, bem como criar uma metodologia para desenvolvimento de produtos otimizados / Abstract: In the current scenery, to be competitive, the companies face the challenge to develop new products in a short space of time, with superior technology to the previous and with reduced costs to guarantee the business survival. And the success is directly connected to the requirements demanded by the customers, where Quality, Reliability, Supply and Price are the minimum that is
expected. In this work, methodologies are discussed, which are used for the Planning and Warranty of the Quality, which should already be used in the phase of the product project conception, because it is here that largely born the quality, the reliability and the final price of the product. The chosen product for analysis is the Automotive Clutch. As a proposed method, firstly an interaction among the Kano¿s Model, QFD, Target Cost and Value Analysis was accomplished to evaluate the attendance degree to the customer's requirements and to determine which the functions whose relative costs are above the relative needs, offering, therefore potential for optimization or even elimination. After that, it is constructed the Fault Tree Analysis (FTA) for identification of the critical components that offer larger fault risks in the system. The main target of the work is the analysis of Reliability and Regression of the results obtained in the Accelerated Life Testing, for determination of the reliability of the clutch in study, components to be improved or optimized, as well as to create a methodology for development of optimized products / Mestrado / Gestão da Qualidade Total / Mestre Profissional em Engenharia Mecanica
