Thus, in most projects involving the construction of single-family housing, there are handcraft features when the building site is understood as a production system. Thus, it is common to observe the pathological manifestations appearance in post-occupational analysis, in addition to non-compliance with deadlines and budgets. In this sense, this thesis suggests that the CI breaks with some technical and cultural paradigms from the use of an industrialized building system, such as Light Steel Frame (LSF) and from the use of assembly lines, focusing the industrialization of singlefamily housing production. This proposal is based on four steps involving theoretical and experimental approaches. The theoretical approaches involved the structuring of a systematic literature review, which were identified gaps in scientific knowledge and the research hypothesis, besides the development of basic theoretical framework, the product definition and production system design. The experimental approach was represented by activities related to computer simulation of the production system and its subsequent optimization. The computer simulation was performed with the ProModel® software where was simulated the production of five hundred housing units from the programming logic of the designed system. Seven scenarios were simulated, with the results of its simulation it was possible to identify the most efficient configuration from optimizing the use of some resources, identified by layout B. In addition, the main results of the simulations show that it is possible to assembly the housing unit designed at 11.14 hours, with a cycle time of 5.56 hours, with the settings of scenario seven. The purpose of this thesis and the results can be considered relevant because promote innovation for both the consumer market and to the academy, since it deals with concepts little used or known in the CI. It also enables greater speed and volume of production, facing the Brazilian housing deficit, with significant quality improvements. / A Indústria da Construção Civil (ICC), no que tange a produção de habitações unifamiliares no Brasil, ainda se caracteriza pelo uso de técnicas e tecnologias que são altamente dependentes do conhecimento e experiência do operário. Assim, na maior parte dos empreendimentos que envolvem a construção de habitações unifamiliares, verificam-se características artesanais quando se aborda o canteiro de obras como um sistema produtivo. Dessa forma, é comum se atestar o surgimento de manifestações patológicas em análises pós-ocupacionais, além do corrente descumprimento de prazos e orçamentos. Neste sentido, a presente tese sugere que a ICC rompa com alguns paradigmas técnicos e culturais a partir do uso de um sistema construtivo industrializado, como o Light Steel Frame (LSF) associado ao uso de Linhas de Montagem, com o objetivo de se industrializar a produção de habitações unifamiliares. Esta proposta se fundamentou em quatro etapas que envolveram abordagens teóricas e experimentais. As abordagens teóricas envolveram a estruturação da revisão bibliográfica sistemática, onde foram identificadas as lacunas do conhecimento científico e a hipótese de pesquisa, além do desenvolvimento do referencial teórico básico, a definição do produto e o projeto do sistema de produção. Já a abordagem experimental foi representada pelas atividades referentes à simulação computacional do sistema de produção e posterior otimização do mesmo. A simulação computacional foi executada com o software ProModel®, em que foi simulada a produção de quinhentas unidades habitacionais a partir da programação da lógica do sistema projetado. Ao todo foram simulados sete cenários; com os resultados de suas simulações foi possível identificar a configuração mais eficiente, a partir da otimização do uso de alguns recursos, identificado pelo layout B. Além disso, os principais resultados das simulações mostram que é possível montar a unidade habitacional projetada em 11,14 horas, com um tempo de ciclo de 5,56 horas com as configurações do cenário sete. A proposta dessa tese e os resultados obtidos podem ser considerados relevantes, pois promovem a inovação tanto para o mercado consumidor quanto para a academia, uma vez que lida com conceitos pouco utilizados ou conhecidos na ICC. Além disso, possibilita maior rapidez e volume de produção, frente ao déficit habitacional brasileiro, com ganhos significativos de qualidade.

Em uma primeira etapa foram apresentados os conceitos e as possibilidades de integração de ambas as teorias e, a partir de um diagnóstico inicial do sistema de abastecimento, foram propostas alterações, de maneira evolutiva, em que melhorias baseadas na Manufatura Enxuta eram implementadas a cada rodada de experimento, culminando com a implementação de melhorias baseadas na Teoria das Restrições, integrando ambos os conceitos. O resultado final obtido corrobora a eficiência da integração das duas abordagens para a melhoria de processos, as quais contribuíram para uma diminuição dos tempos de ciclo de abastecimento na ordem de 89% para a célula alvo estudada, sendo superior ao resultado obtido utilizando-se apenas uma das técnicas, sem que houvesse necessidade de investimentos e/ou despesas significativas. / The large number of global players in the market has led the automotive industry chain to incessantly seek improvements in operations management to increase their results and, based on this fact, this paper presents a proposal for integrating the techniques and approaches of Lean Manufacturing and Theory of Constraints through an action research application, aiming at improving the material supply system of welding cells from a chassis frame assembly line. In the first stage were presented the concepts and possibilities of integration of both theories and, from an initial diagnosis of the supply system, changes were proposed in an evolutionary way, in which improvements based on Lean Manufacturing were implemented on each experiment round, culminating in the implementation of improvements based on the Theory of Constraints, integrating both concepts. The final result confirms the efficiency of the integration of these two approaches as a way to improve processes, which contributed to an 89% decrease of the supply cycle times of the studied target cell. This result is better than the result obtained using only one of the techniques, without the need for investments and / or significant expenses.

Existem muitos estudos e publicações focadas no planejamento e desenvolvimento de novos produtos. Porém, o mesmo não é notado em estudos relativos à implantação destes novos produtos e seus processos na área de manufatura. Para tal, é desenvolvido neste trabalho um modelo de referência consistente para a implantação de novos processos de montagem no setor automotivo. O citado modelo contém a descrição das etapas, as verificações de qualidade, as ações e as necessárias validações do produto produzido no processo de produção em série. O teste da consistência e relevância dessa metodologia ocorre por meio da aplicação do modelo proposto, no desenvolvimento de um processo da montagem de componentes na montagem final. Para a sua avaliação, compararam-se os indicadores de um processo existente em dois momentos: um primeiro, com o processo desenvolvido utilizando-se o método tradicional, e em segundo, com o desenvolvimento e implantação deste mesmo processo, utilizando-se o método proposto de desenvolvimento do processo produtivo, somado a uma avaliação qualitativa do modelo de referência, por meio de uma pesquisa, com especialistas reconhecidos do meio automotivo, validando-se assim o modelo proposto. / Currently, there are many studies and publications focused on the planning and development of new products. However, the same is not noted in studies related to the implementation of these new products and their processes in manufacturing area. For this, a consistent reference model is developed for implementation of new assembly processes in the automotive sector. This model contains a description of steps, quality checks, actions and validations required by the product manufactured in the serial production process. The test of consistency and relevance of this methodology occurs through the application of the proposed model, in the development of a process of component assembly in the final assembly. For its evaluation, the indicators of an existing process were compared in two time points: with the process developed using the traditional method, and secondly, with the development and implementation of this same process, using the proposed development method of the production process. This occurred alongside a qualitative evaluation of the reference model through a survey with recognized experts of the automotive environment, thus validating the proposed model.

For any business, surviving in a competitive market while maintaining all the operational performance indices up to mark is very crucial. There are several theories and techniques to improve the efficiency of the operational performances. Line balancing is one of those well practiced techniques used daily in most of the industries. Line balancing helps balance the assembly lines with regards to man, machine, takt times, etc. This thesis research was done with Electrolux laundry systems, Ljungby in Sweden. With the varying customer demands the case company was balancing its line manually using basic methods. As a part of lean development schemes, Electrolux Ljungby, wanted to transform the line balancing techniques from manual to a fully automated software. The purpose of this research is to determine the company-specific line balancing criteria which should be considered before performing line balancing. This research furthermore lays out a guideline to follow a smooth transition from the manual system of LB to an automated software by concluding the features the software must handle to perform the LB according to required objectives. A case study approach was utilized to collect all the required data to achieve the results. Using the data collection techniques such as interviews, observations and historical analysis we arrived at the data required to design the guidelines with regards to line balancing software features.  The findings suggest that the desired line balancing constraints which are very important in the multi model single sided straight-line balancing problems are flow of materials, assembly precedence, physical constraints, product demand, bill of materials, restricted processes, man power and desired line balancing objectives. Keeping these constraints into consideration the features which are desired in an onlooking line balancing software are the Integration of data and documents/ maximum control, mixed model and option intelligence and analysis, multiple resources, smart variant management, scenario management, yamazumi chart, constraints and reporting tabs. The findings of this thesis can be used as guidelines by any manufacturing industry while they consider buying a new software which can handle Line balancing problems. This research is one of its kind which talks purely about the constraints and desired features only in a specific line balancing scenario. Practitioners can use this as a base for conducting further research on constraints and features pertaining to it, for different line balancing scenarios.

L'industrie est aujourd'hui, comme elle a toujours été, une pierre angulaire de l'économie pour chaque pays développé. Avoir une base solide en entreprises industrielles est très important parce qu’elles poussent et stimulent tous les autres secteurs de l'économie, et offrent également une grande variété d'emplois qui apporte des bonnes conditions de vie dans de nombreux secteurs de la société. L’augmentation de la concurrence mondiale, l’évolution rapide du marché, la nécessité de créer des entreprises stables avec des usines rentables obligent la mise en oeuvre d’une démarche globale prenant en compte à la fois les aspects techniques, économiques, logistiques et sociétaux lors de la conception d’un système de production innovant. L’objectif de cette thèse est de contribuer au développement d’un concept innovant de Systèmes de Production Reconfigurables et Agiles (SPRA) permettant de s'adapter rapidement et efficacement aux exigences imposées du marché, des clients, de la technologie des procédés, de l’environnement et de la société afin que l’entreprise soit dynamique, compétitive et rentable. Dans ces travaux de thèse, la proposition d'un modèle générique et la caractérisation de ce nouveau type de système de production ont été décrits en utilisant le langage de modélisation des systèmes complexes (SysML : Systems Modeling Language). Ensuite, nous avons développé un processus de reconfiguration qui représente une démarche à suivre pour concevoir et implanter une nouvelle configuration. De plus, un pilotage opérationnel adapté au SPRA a été introduit. Enfin, quelques travaux développés au cours de cette thèse ont été partiellement déployés sur un démonstrateur industriel au sein de la plate-forme AIP-PRIMECA Auvergne. / Industry is, today as it has always been, a cornerstone of the economy for any developed country. Having a strong manufacturing base is very important because it impels and stimulates all the other sectors of the economy. It provides a wide variety of job, which bring higher standards of living to many sectors of society, and builds a strong middle class. Increasing global competition, rapid changes in the marketplace and the need to create stable companies with profitable plants require the implementation of a global approach, taking into account technical, economic, logistic and societal aspects in the design of an innovative manufacturing system. The aim of this dissertation is to contribute to the development of an innovative concept of Reconfigurable and Agile Manufacturing Systems (RAMS) to adapt quickly and effectively to the requirements imposed by markets, customers, technology processes, the environment and society, to ensure that the enterprise is dynamic, competitive and profitable. In this thesis work, the characterization and proposal of a generic model for this new type of manufacturing system have been described using the language of complex systems modeling (SysML: Systems Modeling Language). We have developed a reconfiguration process that represents the approach to follow in the design and implementation of a new configuration. In addition, the operational control of a RAMS has been introduced. Finally, some works developed in this thesis have been partially deployed on an industrial demonstrator within the AIP-PRIMECA Auvergne organisation.
