Previous issue date: 2010 / Resumo: A busca da satisfação do cliente e o entendimento de suas necessidades e desejos têm sido objeto de muitos estudos em várias áreas da ciência, necessitando novas metodologias. O Desdobramento da Função Qualidade (QFD) é uma dessas metodologias; é uma ferramenta recente, cuja aplicabilidade vem ganhando forças no mercado contemporâneo e com contínuo aprimoramento e aplicações nas diferentes áreas, destacando-se a de serviços. O mercado de alimentação fora do lar está em franco crescimento, vários são os motivos, dentre eles: a distância da residência, a dificuldade de locomoção e a escassez de tempo para as refeições. Atualmente a Unicamp dispõe, no campus Campinas, de três Restaurantes Universitários (RUs) e 24 Cantinas para atender 50.000 pessoas. Este trabalho teve por objetivo oferecer subsídios para a melhoria dos serviços de alimentação da Unicamp, campus Campinas, através da definição das Características de Qualidade (CQs) da Matriz da Qualidade do QFD para um serviço "ideal", na percepção do cliente. Foram avaliados os três RUs e 21 Cantinas do campus, por 1083 respondentes, todos frequentadores das RUs e Cantinas, sendo também caracterizado o perfil desses clientes. A amostragem, bem como a análise de dados, foram amparadas por técnicas estatísticas e de pesquisa de mercado. As etapas do método QFD foram desenvolvidas com procedimentos adicionais para a avaliação das CQs. Foram construídas duas Matrizes da Qualidade: RUs e Cantinas. Para a Qualidade Planejada dos RUs, das nove Qualidades Exigidas (QEs) levantadas na etapa qualitativa, foram priorizadas Qualidade do local, Qualidade da comida, Refeição balanceada, Novidade e Oferecimento de refeições. Mostrando assim, a preocupação e expectativa dos clientes com relação à saúde e ambiente agradável, oportunidade de sociabilização, principalmente por parte dos estudantes, a maioria dos frequentadores. Para as Cantinas, a ordenação das QEs Novidade, Atendimento, Qualidade da comida, Qualidade do local, Preço e Proximidade, mostra que os clientes são mais preocupados com aspectos da satisfação dos desejos, principalmente para as refeições com novidades. Na extração, definiram-se 42 Características de Qualidade (CQs). Na Qualidade Projetada foram definidas as CQs Acompanhamento técnico e Horas de treinamento como as mais relevantes e que devem merecer maior empenho de implantação para melhorar os serviços. Assim, outras CQs altamente relacionadas com essas também serão melhoradas. A constituição de equipes técnicas com perfis adequados para cada etapa permitiu a evolução dos trabalhos. Na etapa da Qualidade Projetada, foi desenvolvida uma Tabela Auxiliar para a consolidação dos Valores Meta e Priorização das CQs. Assim, procedimentos adicionais na construção da Matriz da Qualidade contribuíram para a condução do trabalho e podem servir para estudos similares. A Matriz da Qualidade do QFD se mostrou eficaz na avaliação de estabelecimentos de serviços de alimentação em um campus universitário; os resultados permitiram identificar com clareza quais CQs se destacaram e, portanto, quais são as mais importantes e que deverão e poderão ser adequadas para o aprimoramento dos estabelecimentos de serviços de alimentação da Unicamp / Abstract: The client satisfaction and the understanding of their needs and desires has been the object of studies conducted in various scientific areas. Thus, new methodologies are necessary. The Quality Function Deployment (QFD) is one of such methodologies; is a recent tool and it's applicability has been gaining strength in the contemporary market with continuous improvements and applications in various fields, with emphasis in service areas. The number of people eating out in commercial food service outlets is rising, due to various reasons: distance from home, difficulties in transportation and lack of time for meals. Currently, Unicamp houses 3 universitary restaurants (URs) and 24 Cafeterias (private food establishments), at Campinas campus, to serve 50,000 people. The current work aims to offer subsidies to contribute towards the improvement of Unicamp food services through definition of Quality Characteristics (QC) from the QFD Quality Matrix for an "ideal" service, according to the client's perception. The 3 URs and 21 cafeterias were evaluated by 1,083 respondents. All respondents were URs and cafeteria clients and their profiles were also characterized. The sampling and data analysis were corroborated by statistical and market research techniques. The QFD method steps were developed with additional procedures for the QCs evaluations. Two different Quality Matrix were built: URs and Cafeterias. For the Planned Quality of the URs, from nine Demanded Qualities (DQs) raised at qualitative step, Location quality, Food quality, Balanced meal, Novelty and Offer of meals were prioritized. These show client concerns and expectations, especially from the students, who represent the largest public in terms of absolute numbers, with relation to health, pleasant ambient and socialization opportunity. For the cafeterias DQs were ordered as follows: Novelty, Service, Food quality, Location quality, Price and Proximity. This demonstrates that the clients are more concerned with aspects related to desire satisfaction, mainly in terms of meal novelties. During the extraction process, 42 Quality Characteristics (QCs) were defined. In Projected Quality the QCs Technical assistance and Training time were defined as the most relevant and deserve greater establishment efforts in order to enhance the services. Thus, other QCs highly related to these will also be improved. The technical teams with the specific profiles demanded by each step was important for the work evolution. In the Projected Quality step, an Auxiliary Table was developed for the consolidation of the Target Values and QC Prioritization. Thus, additional procedures on Quality Matrix construction contributed for the work development and may be useful for similar studies. The QFD methodology was shown to be efficient to evaluate the food service in an university campus. The results showed to the most relevant CQs and those that may and should be used to enhance the quality of the food service establishments at Unicamp / Doutorado / Tecnologia Pós-Colheita / Doutor em Engenharia Agrícola

Design and Construction of Chassis for Uniti L7e VehiclePavan Kumar Maareddygari, Pavan Kumar, Anoop Bharadwaj Yellambalse Prem Kumar, Anoop January 2017 (has links)
Chassis is the primary structural component of an automobile. It is the main supporting structure of a vehicle to which all other systems like braking, suspension and differential are attached. In this thesis, a methodology for L7e category vehicle chassis design and structural stability analysis is presented. The present car being developed at Uniti Sweden AB is classified as L7e category vehicle as per the European Union, therefore the chassis developed in this thesis considers the specific characteristics that vehicles under this category demands for. A literature study is carried out to review various existing designs of vehicle chassis, latest innovations and advanced materials used to manufacture the same. The various types of forces and stresses commonly acting on chassis structures are analyzed and their effects on the vehicle is understood. After completing literature study, several findings are listed in a systematic manner, by providing ample arguments to justify each of them. The pro-con analysis is conducted to evaluate merits and demerits of each alternative type of chassis and the material to manufacture it. The most essential design criteria are derived from the QFD (Quality function deployment) which then acts as important guidelines during the actual design process. Structural chassis frame is designed as per the design criteria, using the CAD software CATIAV5R19 and the structural stability of the same is tested and analyzed using ANSYS 15.0 software. From the results of these analysis tests the static structural stability of the design is confirmed.

應用統計方法找尋配方之研究蔡淑茜, Tsai, Shu-Chien Unknown Date (has links)
本研究嚐試找出果凍的最適配方,利用品質機能展開將顧客需求和技術項目結合,找出顧客所重視的技術項目,再依此規劃實驗收集資料。以田口方法和迴歸分析法對數據分析,以提出最適配方。
利用田口方法和迴歸分析法兩種方法找尋最適配方,發現依照不同品質特性所找出的最適配方結果是不相同的,而同時考慮兩種品質特性整體損失函數所找出的最適配方,才能使整體期望損失估計值最小(小於兩個品質特性各別所找出最適配方期望損失估計值的加總)。
由於產品時常有多個品質特性,建議找最適配方時,能同時考量各品質特性的總損失,唯有如此才能找到真正使損失最低的最適生產組合。 / The research goal is to try to find optimal setting combination of one product. We take advantage of QFD (Quality Function Deployment) method to combine the needs of customers and producing technologies; by this, we can tell which technologies are more important for customers’needs. After knowing which technologies are important, we could order an experiment to collect raw data. Using Taguchi Method and Regression Analysis Method to analyze the raw data, we can extract optimal solutions.
We found that we could get different optimal solution by different character of a product. Therefore, only considering all characters of a product at the same time, we can get the really optimal setting combination; or we just could get sub optimal setting combinations.
