Pełny tekst źródłaWorldwide, it is known that, over the years, the industry of the plastic sector is moving at a level of growth that is mainly related to its broad capacity for transformation, combination, durability and other applications that, if correctly used, contribute to improving the capacity of competitiveness of organizations facing other converters. However, this growing situation means that production processes are more saturated, generating higher losses in time that impact on non-compliance with demand, and since plastic production plants sell machine time, this situation affects the profitability of the same In order to mitigate these situations, various efforts have been made to come up with philosophies and methodologies that allow finding the solution to these problems, due to the great importance for companies to work with the highest efficiency in their processes and thus seek to increase their productive availability to increase sales volume In this regard, the implementation of the Lean Manufacturing methodology applied under the support of the Deming cycle whose main objective will be to develop a strategy based on the PHVA cycle that will increase machine efficiency in a sustained manner is approached. Its contribution is developed around the successful application of the combination of the Lean tools selected under the Deming scheme and developed under a Gantt timetable for the solution of the case and that are developed in this article, being able to serve as an initial guide to other technicians who They seek to increase the productivity of their processes in other factories in the sector.

Pełny tekst źródłaMalnutrition is a significant threat to human health. In Togo, cowpea puree, known locally as "Adowè", is potentially rich in nutrients and can be used to fight against malnutrition. However, this puree has seen reduced production and consumption over time. The aim of this thesis is to contribute to the fight against protein-calorie malnutrition through the use of endogenous agricultural resources, such as cowpea seeds (plant proteins). In a world where animal proteins consumption is on the rise, this work also helps to contribute towards environmental preservation. Therefore, promoting the development and rehabilitation of "Adowè" requires us to study its production on an industrial scale. Experiments were carried out to determine the cooked state of the cowpea seeds by mechanical compression. The rheological properties of the "Adowè" puree were also determined. The results obtained show that the cooked state of the seeds could be assessed by physical quantities. The activation energy for the cooking of theseeds has also been determined. These parameters will therefore be the basis for the energetic control of the seed cooking process. Finally, the rheological characterisation of the puree was carried out using two methods. For purees with mass concentrations between 12 and 20%, "Adowè" is a yield stress fluid. Beyond 20% concentration, oscillatory and steady shear viscosity measurements of the puree become intractable. Therefore, back extrusion method was used to quantify the viscosity of the puree at 31±2% (mass/mass). These results are useful fortransitioning from artisanal to industrial production of "Adowè"

Ett dotterbolag till Stoneridge, Inc. är företaget Stoneridge Electronics. De är specialiserade på instrument kluster och färdskrivare som tillverkas i produktionsanläggning i Örebro. Denna examensarbete fokuserar på produktionslinje av ett instrumentkluster som heter Angela. I nära samarbete med Stoneridge Electronics,målet var att hitta sätt att förbättra produktionen av Angela linje med minst 10 % jämförtmed de tre bästa månaderna när det gäller produktion från året innan. Angela-linjen analyserades grundligt och från olika perspektiv med lean verktyg som värdeflödesanalys, spaghetti diagram och kontinuerlig förbättring. Slutligen användes simuleringsprogrammet ExtendSim för att simulera och analysera olika förslag. Resultaten visar att olika steg kan vidtas för att förbättra effektiviteten och produktionen av produktionslinjen med så mycket som 16.3%. På grund av att andra produktionslinjer inom produktionen liknar den som projektet genomfördes på, kan projektresultaten vara tillämpliga för andra linjer också.

Pełny tekst źródłaThe main difficulty when an Active Pharmaceutical Ingredient (API) is orally administered is to guarantee that the clinical dose of the API will be dissolved in the available volume of gastrointestinal fluids. However, about 40% of APIs with market approval and nearly 90% of molecules in the discovery pipeline are poorly water-soluble and exhibits a poor oral absorption, which leads to a weak bioavailability. Amorphous solid dispersions (ASD) are considered as one of the most effective strategies to solve solubility limitations of poorly-water soluble compounds and hence, enhance their oral bioavailability. Despite their introduction as technical strategy to enhance oral APIs bioavailability more than 50 years ago, ASD formation and physical stability remains a subject of intense research. Indeed, several factors can influence the physical storage stability of ASD, among them, the glass transition temperature of the API-carrier binary mixture, the apparent solubility of the API in the carrier, interactions between API and carrier, and the manufacturing process. This thesis consisted of two parts that aim on developing new formulations of ASD of an antiretroviral API, Efavirenz (EFV), dispersed in an amphiphilic polymer, Soluplus, by using two different processes, Spray-drying (SD) and Hot-melt extrusion (HME). EFV is the class II BCS API of our choice because it is a challenging API for new formulations. It needs higher-dosed ASDs, for which chemical and physical stability during storage and dissolution will be critical. Aiming a rational development of high-loaded EFV-Soluplus ASDs, the first part focused on the construction of a temperature- composition EFV-Soluplus phase diagram. The phase-diagram was constructed from a thermal study of recrystallization of a supersaturated ASD (85 wt% in EFV), generated by spray drying. To our knowledge, this is the first study reporting a phase-diagram for this binary system. This phase-diagram is very useful and demonstrated that the EFV solubility in Soluplus ranges from 20 wt% (25 °C) to 30 wt% (40 °C). ASD of EFV in Soluplus containing more than 30 wt% of EFV should be monitored over storage under typical temperature conditions. This phase-diagram might be considered as a preformulation tool for researchers studying novel ASD of EFV in Soluplus, to predict (thermodynamic and kinetic) stability. ASD prepared by different techniques can display differences in their physicochemical properties. The second part of this thesis focused on the manufacturing of ASD by HME or SD processes. This study clearly shows that ASD is a useful formulation strategy to improve the aqueous solubility and the dissolution rate of EFV from EFV-Soluplus binary mixtures. HME and SD manufacturing processes demonstrated to be efficient to generate ASDs in a large range of compositions and loads of EFV. The optimization of EFV to Soluplus ratio can be used to tailor the release kinetics from ASD. The choice of a high EFV load exceeding the thermodynamic solid solubility in Soluplus is possible but it needs the consideration of its kinetic stability over time

Pełny tekst źródłaThis research project focuses on the application of process improvement techniques in a clothing manufacturer to address delay problems in workflow in the factory. The objective of the research is threefold; investigate delays at the beginning of production and make suggestions, show the usefulness of continuous improvement techniques in improving activities in a clothing manufacturer and demonstrate how action research can be used in doing research in production and operation management. Using tools such as flow charts, check sheets, pareto analysis, fishbone diagrams, interviews and the "ask why five times" tool, an investigation into delays led to a second investigation into sewing defects. This established that these sewing defects are caused mainly by time constraints, the malfunctioning of machines, the wrong handling of garments, and previous operations. After an investigation using the above tools it was established that these defects could be addressed by setting realistic targets, doing regular maintenance on machines, cautioning operators to be more careful during their operations, and encouraging regular checks on garments before the next operation. The action learning methodology led to the following lessons; selecting a correct measuring tool is important, that not all tools need to be used, and that it takes time to do a research project using this method.

Pełny tekst źródłaO desenvolvimento de novas tecnologias em diferentes áreas da ciência tem impulsionado e mudado profundamente o modo de ser e estar no mundo industrial. Estas tecnologias, a globalização e a procura expõem a indústria a um mercado muito competitivo. Os clientes são cada vez mais seletivos e exigentes, um fato que leva a indústria a investir seriamente em tecnologias de ponta com o objetivo de ser mais eficiente, economicamente sustentável e satisfazer os seus clientes. Neste contexto, a indústria de moldes começou a investir em tecnologias, tais como, a tecnologia SLM (Selective Laser Melting) ou Fusão seletiva a laser. Fusão seletiva a laser, que é baseada no princípio de fabricação de objetos por adição sucessiva do material, é reconhecida como uma tecnologia de fabrico muito promissora. Esta tecnologia é adequada para o fabrico de objetos com elevada complexidade geométrica que seria impossível por outras formas. Esta tecnologia tem um ponto fraco relacionado com o acabamento superficial, portanto, há uma necessidade de fresar-se o objeto para a remoção do excesso do material ou seja a rugosidade. Para o efeito e com o objetivo de otimizar as sucessivas fases aditivas e subtrativas, propusemos o uso do eixo médio e suas extensões como uma forma prática de resolver o problema e obter um ótimo acabamento superficial. A noção do eixo médio está relacionada com a teoria dos diagramas de Voronoi e já foi proposto em diversos processos de fresagem. É neste contexto que precisamos encontrar a melhor técnica que melhor se adequa à nossa situação para determinar exata ou aproximadamente o eixo médio.
The emergence of new technologies in different scientific areas has been boosting and deeply changing the industrial world. Globalization and associated demand have been exposing the industry to a very competitive market. The clients are increasingly demanding and selective, which compels the industry to seriously investing in high-end technologies in order to be more efficient, economically sustainable and to be able to satisfy its clients. In recent years the mould industry has been investing in new technologies, such as Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), Electron Beam Melting (EBM), Selective Laser Melting (SLM).Their differences are essentially in mechanical details. Selective laser melting, which is based on the principle of material incremental manufacturing, has been recognised as a promising additive manufacturing technology. The technology is suited for creating geometrically complex components that can not possibly or feasibly be made by any other means. Since this technique has a weak point related to the surface finishing, there is a need to use techniques such as milling to remove the surplus material. To plan and optimize the successive additive and subtractive phases, we propose to use the medial axis and certain extensions of it, as a practical way of determining the best possible finishing quality of the produced object. The notion of medial axis is closely related to the theory of Voronoi diagrams, and has been proposed in several milling applications that involve motion planning. To that end we have to find which of the available construction strategies best suits our needs to determine exactly or approximately the medial axis.

Pełny tekst źródłaO presente projeto de dissertação, realizado no âmbito do Mestrado Integrado em Engenharia e Gestão Industrial, foi desenvolvido em contexto industrial na empresa AptivPort Services S.A, em Braga. Esta organização, inserida no ramo da indústria automóvel e dedicada à produção de componentes plásticos e eletrónicos para o fabrico de sistemas de navegação, controlo e infotainment, procura agora, através do seu programa Lean 2.0, adotar um conjunto de ferramentas e metodologias lean que permitam a eliminação de desperdícios, redução de custos e aumento de qualidade do seu sistema produtivo. O principal objetivo deste projeto consiste em analisar, diagnosticar e melhorar, com recurso a um conjunto de ferramentas e metodologias lean, o desempenho do sistema produtivo de um dado “produto A”, com principal foco nas métricas de Work in Process (WIP), lead time, produtividade e qualidade. Em primeiro lugar, realizou-se a revisão da literatura em torno da filosofia Lean Manufacturing, nomeadamente ao nível das bases que suportam esta filosofia e a algumas das principais ferramentas e metodologias que serviram de base teórica para o desenvolvimento do projeto. Seguidamente, e tendo por base a metodologia de investigação action-research, efetuou-se a análise e diagnóstico da fase inicial do processo produtivo em questão, fazendo uso de ferramentas como o estudo de tempos, análise ABC, Value Stream Mapping (VSM), e diagrama de spaghetti. Assim, através destas, foi possível identificar um conjunto de problemas como a falta de capacidade produtiva; o excesso de WIP em determinados setores da produção; a elevada incidência do modo de falha – “No Trouble Found” (NTF); a elevada quantidade de ações de transporte e movimentação; e ainda, algumas insuficiências relacionadas com o sistema de gestão visual da fábrica e com o indicador de desempenho chave – Overall Equipment Effectiveness (OEE). Por fim, através da implementação de propostas de melhoria como o aumento da capacidade produtiva, a implementação de um novo sistema de transportes e a criação de um plano de reação standard e de um standard de gestão visual, foi possível obter uma redução da quantidade de WIP presente no sistema produtivo em questão de cerca de 10,5% (100 759 € de capital parado); uma redução do lead time de cada uma das placas eletrónicas afetas ao “produto A” de cerca de 4,68 horas e 1,15 horas, cada; um aumento de produtividade de cerca de 7,8%; e ainda, algumas melhorias de qualidade não quantificadas. Em suma, tudo isto terá resultado numa poupança monetária anual de cerca de 46 143 €/ano.
The present dissertation project, carried out under the Integrated Master's Degree in Industrial Engineering and Management, was developed in an industrial context at AptivPort Services S.A, in Braga. This organization, inserted in the field of the automotive industry and dedicated to the production of plastic and electronic components for the manufacture of navigation, control, and infotainment systems, is now seeking, through its Lean 2.0 program, to adopt a set of lean tools and methodologies, that allow for the elimination of waste, cost reduction and increase in quality of its own production system. The main purpose of this project is to analyze, diagnose and improve, using a set of lean tools and methodologies, the performance of the production system of a given “product A”, focusing mainly on the Work in Process (WIP), lead time, productivity and quality metrics. First, a literature review was carried out on the Lean Manufacturing philosophy, namely, on the bases that support this philosophy, and on some of the main tools and methodologies that served as a theoretical basis for the development of the project. Then, based on the action-research methodology, an analysis and diagnosis of the initial phase of the production system in study was carried out, using tools such as time study, ABC analysis, Value Stream Mapping (VSM), and the spaghetti diagram. Thus, with these, it was possible to identify a set of problems such as the lack of productive capacity; the excess of WIP in certain sectors of production; the high incidence of the failure mode – “No Trouble Found” (NTF); the high amount of transport and motion actions; and also, some insufficiencies related with the plant’s visual management system and with the Overall Equipment Effectiveness (OEE) key performance indicator. Finally, through the implementation of improvement proposals such as the increase in production capacity, the implementation of a new transport system and the creation of a standard reaction plan and a visual management standard, it was possible to obtain a reduction in the amount of WIP present in the studied production system of approximately 10,5% (the equivalent of 100 759 € of idle capital); a reduction in the lead time of each one of the electronic boards linked to “product A” of around 4,68 hours and 1,15 hours, each; an increase in productivity of about 7,8%; and also, some unquantified quality improvements. In short, all this resulted in an annual saving of 46 143 €/year.

Este projeto desenvolvido em ambiente industrial insere-se no último ano do Mestrado Integrado em Engenharia e Gestão Industrial para conclusão do curso. O projeto foi desenvolvido na Continental Mabor, devido à necessidade da empresa analisar um processo produtivo que gera uma elevada quantidade de material não conforme que pode ser reaproveitado. Como tal, o projeto consistiu em reduzir este desperdício e procurar que seja reutilizado nas melhores condições. O principal objetivo consiste na análise da situação e no desenvolvimento de propostas de melhoria para aumentar a produtividade do processo de extrusão de pisos. Aplicando o Lean Six Sigma (LSS), conseguiu-se identificar as variáveis que influenciam a qualidade da produção de pisos através de várias técnicas e ferramentas que as filosofias Lean Manufacturing e Six Sigma dispõem e que são a base do LSS. Recorrendo ao ciclo DMAIC (Define, Measure, Analyze, Improve, Control), percorre-se fases para a compreensão e resolução do problema. Nas diferentes fases, executam-se técnicas e ferramentas associadas ao Lean Manufacturing e Six Sigma permitindo uma análise estruturada de diferentes causas que influenciam negativamente o processo de extrusão e consequentemente a identificação de várias oportunidades de melhoria. A quantidade de propostas de melhoria implementadas permite considerar que o projeto foi um sucesso. Os objetivos da dissertação foram atingidos, visto que a quantidade de material não conforme criado durante o processo de extrusão de pisos foi reduzida. Os custos com a qualidade diminuíram e a produtividade aumentou.
This thesis describes a project to improve a productive process of a company from the automotive industry. This project developed in an industrial environment is part of the final year of the Master in Industrial Engineering and Management for course completion. The project was developed in Continental Mabor, which has a production process that generates a quantity of nonconforming material that can be reused. As such, the project was to reduce this waste and seek to be reused in the best conditions. The main objective consists to analyze the situation and the development of proposals for improvement to enhance the proper functioning of the extrusion process. Applying Lean Six Sigma (LSS), the identification the variables that influence the quality of the production treads was obtained through various techniques and tools that philosophies Lean Manufacturing and Six Sigma have and which are the basis of the LSS. Using the DMAIC cycle (Define, Measure, Analyze, Improve, Control), runs up phases for understanding and resolve the problem. In different phases, executing techniques and tools associated with Lean Manufacturing and Six Sigma allowing structured analysis and different causes that negatively influence the extrusion process and hence the identification of several opportunities for improvement. The amount of improvement proposals implemented suggests that the project was a success. The costs were reduced to quality and productivity increased, since the amount rejected of tread decreased.

Os objetivos desta dissertação são reduzir em 20% o tempo gasto em atividades que não acrescentam valor no setor da produção e reduzir erros do planeamento e da produção em 50% até 30 de Junho de 2015. Este projeto iniciou-se com uma revisão literária exaustiva na área de Lean Manufacturing no sentido de se aprofundar conhecimentos sobre esta temática e sobre quais as ferramentas que poderiam ser utilizadas ao longo do trabalho. Já no shoop floor foi feita uma recolha de informações no sentido de se perceber o funcionamento da área produtiva da empresa e posteriormente foi efetuado um diagnóstico ao sistema produtivo da mesma utilizando ferramentas como o VSM, o diagrama de Spaghetti, um registo de observações às atividades desenvolvidas na produção e uma análise de erros ao planeamento e à produção. Deste diagnóstico surgiram algumas propostas de melhoria, especificamente uma reorganização do layout, a instalação de um software de procura de cortantes, a criação de um armazém de matéria-prima, a implementação de um novo sistema para eliminação de restos de materiais, a aplicação de 5S numa bancada de ferramentas, rotulagem das estantes e gestão visual nas estantes de cortantes. Os colaboradores da zona administrativa tomaram também a iniciativa de efetuar algumas melhorias à sua área, nomeadamente na organização de dossiers, no número de vias utilizadas nos documentos e na criação de um manual de procedimentos. Como resultado, foi possível reduzir os desperdícios no setor da produção em 38,60% e foi também possível reduzir o número de erros que se verificavam na produção e no planeamento em 85,71%.
The present dissertation portrays the implementation of Lean Manufacturing tools in industrial environment, more specifically in the production line of the company Flexospuma, Lda, inserted in the footwear components industry. The goals of this dissertation are to reduce in 20% the time spent in activities that don’t add value to the production process and also reduce planning and production errors in 50% until June 30, 2015. This project began with a thorough literature review in the area of Lean Manufacturing in an effort to deepen the knowledge on this subject and learn which tools could be employed throughout the work. Already in the shoop floor a collection of information was made in order to understand the functioning of the company’s production line, followed by a diagnosis of the same production line using tools like VSM, Spaghetti diagram, an event log and error analysis. From the diagnostic some improvement proposals emerged, specifically, a reorganization of the layout, improvements such as the implementation of search engine software designed to search cutting molds, the creation of a storage area for raw materials, the implementation of a new system for the disposal of leftover materials, application of 5S in the tool shelf, labeling of shelves, and visual management in the cutting molds shelfs. Employees of the administrative area also took the initiative to make some improvements to their area, namely, in file organization, in the number of copies used per document and in the creation of a procedure manual. As a result, it was possible to reduce waste in the production line in 38,60% and was also possible to reduce the number of errors detected in production and planning in 85,71%.

Pełny tekst źródłaThe Japanese company Toyota was pioneered in the application of a new form of management, through the development of the Toyota Production System (Toyota Production System, TPS). This system integrates principles of the "Lean Manufacturing” (LM) philosophy, using the methods "Just-in-time", "Kanban" and "Heijunka". These findings emphasize the differentiation verified in the competitive capacity of the enterprises, which is due to differences at the organizational level and proper adaptation of LM tools to the activity of the company. The LM may help the neediest companies organizationally, and considers that the difficulties in the application of Lean practices, are due mainly to three factors: lack of commitment, reduce of qualified employees and intermittent production environments. In this thesis, we intended to analyze the current state of the art in what concern to methods of LM. This literature review helped to start our proposal, which consists in the implementation of the Lean practices to rapid response cases in the assistance of vehicle maintenance in road by the T Company. To achieve our proposal, we have elaborated the approach to the problem, developing an implementation support tool LM, consisting of Pareto analysis, spaghetti diagram, VSM current state, VSM future state, product analysis, means to apply, and apply state future. The study was applied to a T Company vehicle involved in the assistance of vehicles in the road, and as a starting point we studied a more competitive product value. We also presented a proposal for the desired improvements using computer aided design technologies. Finally, this study intends to launch and initiate continuous improvement through kaizen events, in order to involve employees of the institution and benefit from the knowledge acquired and also to motivate the team to the expected constant improvement.
