No. of bitstreams: 1 DissSJB.pdf: 1198587 bytes, checksum: 1d294b78ab991245636eb211cc176f0f (MD5) Previous issue date: 2006-12-15 / Financiadora de Estudos e Projetos / This research presents the application of the Strategic Manufacturing Management Paradigm (SMMP) identification method and the most appropriate SMMP for an organization in the three main footwear areas of the state of São Paulo: Franca, Birigui and Jaú. This method was developed by Godinho Filho e Fernandes (2006a). The research procedure used was survey. Thirty companies were selected using random probabilistic sampling, where 10 of them were interviewed in each studied area. Only 29 companies that composed the sample participated in the research. Based on the identification of the used SMMPs, it was verified that most of the companies didn t have strategic focus, which was elucidated by cases of inconsistency among ends and means. The SMMPs identified in some companies were: Responsive manufacturing and Mass customization. During the identification of the ideal SMMPs, it was observed that most of the companies focused non-coherent objectives due to the turbulence of the market in which they are inserted into. Amongst the SMMPs considered appropriate to some companies, the following could be identified: Responsive Manufacturing/ Mass Customization and Mass Customization/Agile Manufaturing. This dissertation presents contributions for the Production Management literature, by means of the identification of the possible types of strategic integration in an organization, as for the Brazilian shoe factoring market, supplying relevant information for a field that is in crisis, besides motivating new researches on the researched theme. / O presente trabalho apresenta a aplicação do método de identificação do Paradigma Estratégico de Gestão da Manufatura (PEGEM) utilizado e do PEGEM mais adequado para uma empresa nos três principais pólos do estado de São Paulo: Franca, Birigui e Jaú. Este método foi desenvolvido por Godinho Filho e Fernandes (2006a). O procedimento de pesquisa utilizado foi a pesquisa de avaliação, também conhecida como survey. Foram selecionadas 30 empresas por meio de amostragem probabilística e aleatória, na qual foram entrevistadas 10 em cada pólo estudado. Apenas 29 empresas que compunham a amostra participaram da pesquisa. Na identificação dos PEGEMs utilizados, verificou-se que a maioria das empresas se encontra sem foco estratégico, apresentando também, casos de inconsistência entre fins e meios. Os PEGEMs identificados em algumas empresas foram: Manufatura Responsiva e Customização em Massa. Durante a identificação dos PEGEMs ideais, observou-se que a maioria das empresas foca objetivos não coerentes com a turbulência do mercado em que atuam. Dentre os PEGEMs considerados adequados a algumas empresas, identificou-se: Manufatura Responsiva/Customização em Massa e Customização em Massa/Manufatura Ágil. Esta dissertação apresenta contribuições tanto para a literatura em Gestão da Produção, por meio da identificação dos tipos possíveis de integração estratégica em uma organização, como para o setor calçadista brasileiro, fornecendo informações relevantes para um setor que está em crise, além de motivar novas pesquisas sobre o tema pesquisado.

Sonia Teresa de Castro Coimbra Campos 01 October 2011 (has links)
A gestão de Manufatura pela prática das ferramentas de manufatura enxuta, o Lean Manufacturing, tem sido amplamente discutida e tem sido um desafio para as empresas que se dispõem a seguir nesta direção, independente do seu porte ou ramo de negócio. A grande dificuldade encontrada está em conhecer se as ferramentas utilizadas estão corretamente aplicadas, entendidas e trazendo resultados para a Empresa. Este trabalho apresenta um sistema gerencial, o Lean Assessment, que busca a solução para identificar o estágio de implementação das ferramentas de manufatura enxuta, avaliando o estado corrente da aplicação dos seus princípios pela empresa, tais como: gestão de pessoas, padronização, qualidade, tempo de execução e melhoria contínua. Este estudo identifica, analisa e avalia estas ferramentas, apresentando as oportunidades para as melhorias que devem ser realizadas, no sentido de redirecionar o plano de implementação, buscando o seu alinhamento, eliminando os gaps encontrados, adotando uma gestão consistente das práticas de implementação e a sua relação ao plano de negócios, levando a empresa a um crescimento sustentável com maior competitividade no mercado. O Lean Assessment permite que as empresas possam implementar e ajustar as ferramentas priorizando-as, conforme os seus recursos humanos e financeiros. Partindo do princípio, que este sistema é a busca de soluções para as empresas através da eliminação dos desperdícios e processo de melhoria contínua, identificou-se a oportunidade de aplicar este sistema de avaliação, para verificar o nível de implementação destas ferramentas e consequentemente servir de base para a elaboração de um plano de ação adequado a empresa, buscando a migração do sistema tradicional de manufatura para o sistema de manufatura enxuta. / The management of Manufacture for practical of the lean manufacturing tools, "Lean Manufacturing", has been widely discussed and has been a challenge for those companies willing to follow to this direction, regardless of their size or business field. The difficulty lies in knowing if the used tools are correctly applied, understood and delivering results for the company. This study presents a management system, Lean Assessment, which seeks the solution to identify the level of implementation of lean manufacturing tools, evaluating the current state of the application of its principles by the company, such as: people management, standardization, quality, responsiveness and continuous improvement. Lean Assessment will allow to identify, analyze and evaluate the tools, presenting opportunities for the improvements that should be performed in order to redirect the implementation plan, searching its alignment, eliminating the gaps found by adopting a consistent management practices implementation and its relation to the business plan, leading the company to a sustainable growth with increased market competitiveness. The Lean Assessment will allow companies to implement and adjust the tools prioritizing them, as their human and financial resources. Assuming that this system is the search for solutions to companies through the waste elimination and continuous improvement process, we identified the opportunity to apply evaluation to check the status of these tools and therefore serve as baseline for developing an appropriate action plan, seeking to migrating from a traditional manufacturing to a lean manufacturing system.

The development of a hybrid knowledge-based Collaborative Lean Manufacturing Management (CLMM) system for an automotive manufacturing environment: The development of a hybrid Knowledge-Based (KB)/ Analytic Hierarchy Process (AHP)/ Gauging Absences of Pre-Requisites (GAP) Approach to the design of a Collaborative Lean Manufacturing Management (CLMM) system for an automotive manufacturing environment.

Moud Nawawi, Mohd Kamal January 2009 (has links)
The automotive manufacturing facility is extremely complex and expensive system. Managing and understanding the dynamics of automotive manufacturing is a challenging endeavour. In the current era of dynamic global competition, a new concept such as Collaborative Lean Manufacturing Management (CLMM) can be implemented as an alternative for organisations to improve their Lean Manufacturing Management (LMM) processes. All members in the CLMM value chain must work together towards common objectives in order to make the LMM achievable in the collaborative environment. The novel research approach emphasises the use of Knowledge-Based (KB) approach in such activities as planning, designing, assessing and providing recommendations of CLMM implementation, through: a) developing the conceptual CLMM model; b) designing the KBCLMM System structure based on the conceptual model; and c) implementing Gauging Absences of Pre-requisites (GAP) analysis and Analytic Hierarchy Process (AHP) approach in the hybrid KBCLMM. The development of KBCLMM Model is the most detailed part in the research process and consists of five major components in two stages. Stage 1 (Planning stage) consists of Organisation Environment, Collaborative Business and Lean Manufacturing components. Stage 2 (Design stage) consists of Organisation CLMM Capability and Organisation CLMM Alignment components. Each of these components consists of sub-components and activities that represent particular issues in the CLMM development. From the conceptual model, all components were transformed into the KBCLMM System structure, which is embedded with the GAP and AHP techniques, and thus, key areas of potential improvement in the LMM are identified for each activity along with the identification of both qualitative and quantitative aspects for CLMM implementation. In order to address the real situation of CLMM operation, the research validation was conducted for an automotive manufacturer¿s Lean Manufacturing Chain in Malaysia. Published case studies were also used to test several modules for their validity and reliability. This research concludes that the developed KBCLMM System is an appropriate Decision Support System tool to provide the opportunity for academics and industrialists from the fields of industrial engineering, information technology, and operation management to plan, design and implement LMM for a collaborative environment. / Universiti Utara Malaysia and Ministry of Higher Education of Malaysia

<b>LASER PROJECTOR-ASSISTED COMPOSITE MANUFACTURING</b>

Yuwei He (19064723) 10 July 2024 (has links)
<p dir="ltr">Composite materials have gained popularity and favor in the aviation and aerospace industries. Their distinctive blend of properties transformed the design and material selection of aircraft and spacecraft, providing significant advantages in terms of weight reduction, fuel efficiency, structural integrity, and environmental sustainability. While multiple automated technologies for composite manufacturing, such as the AFP/ATL machine's robotic arms, are currently being used in the industry, manual layup is still the primary choice for complicated geometry and small-scale manufacturing. For manual layup assistance, physical templates and a laser projector can assist the laminator for ply placement. However, physical templates can be costly, complicated to manufacture, and inefficient. On the other hand, the implementation of laser projection can assist the laminator with ply placement seed point identification and eliminate the need for a physical template, making it a more sustainable option. This study is designed to determine whether the laser projector can assist the laminator in ensuring a constant overlap length, which might improve material structural performance and reduce manufacturing time.</p>

A FRAMEWORK TO INVESTIGATE KEY CHARACTERISTICS OF DIGITAL TWINS AND THEIR IMPACT ON PERFORMANCE

Edwin S Kim (8974793) 29 April 2022 (has links)
<p>The modern world of manufacturing is in the middle of an industrial revolution with the digital and physical worlds integrating through cyber-physical systems.  Through a virtual model that is able to communicate with its physical system known as the Digital Twin, catered decisions can be made based on the current state of the system.  The digital twin presents immense opportunities and challenges as there is a greater need to understand how these new technologies work together. </p> <p><br></p> <p>This thesis is an experimental investigation of the characteristics of the essential components of the Digital Twin.  A Digital Twin Framework is developed to explore the impacts of model accuracy and update frequency on the system’s performance measure. A simple inventory management system and a more complex manufacturing plant is modeled through the framework providing a method to study the interactions of the physical and digital systems with empirical data.</p> <p><br></p> <p><br></p> <p>As the decision policies are affected by the state changes in the system, designing the Digital Twin must account for the direct and indirect impact of its components. </p> <p>Furthermore, we show the importance of communication and information exchange between the Digital Twin and its physical system.  A key characteristic for developing and applying a digital twin is to monitor the update frequency and its impact on performance.  Through the study there are implications of optimal combinations of the digital twin components and how the physical system responds.  There are also limits to how effective the Digital Twin can be in certain instances and is an area of research that needs further investigation.  </p> <p><br></p> <p>The goal of this work is to help practitioners and researchers implement and use the Digital Twin more effectively.  Better understanding the interactions of the model components will help guide designing Digital Twins to be more effective as they become an integral part of the future of manufacturing.</p>
