Due to the competitive advantages derived from appropriate logistical operations, and the high costs associated with it, companies began to consider academic studies conducted in this area in order to optimize its processes and satisfy its customers. Logistics, an essential part of supply chain management, is also responsible for all internal movements within a manufacturing facility, ensuring that production lines are properly stocked. This category is called In-Plant Logistics and the target of this case study. It was observed that the following company, which belongs to soap powder manufacturer business, faces numerous stops of its production lines. For that reason, it was proposed to create a staging area, which will ensure greater visibility of the production plan, avoiding replannings, besides relieving the work of overloaded departments

As a result of the industrial competitiveness increase in recent decades, concern about process improvements has been growing significantly. Lean Thinking principles are being more and more applied in the different sectors of the industry and aim to reduce costs, which can generate satisfactory results for an organization. Besides the application of lean tools on workstations, Lean Thinking seeks cultural change of the employees. Although the concepts of this management philosophy are widely disseminated, many organizations find barriers in their implementation and management. This study seeks to identify and evaluate the critical success factors in the implementation of Lean Thinking based on a qualitative research in the manufacturing environment of a multinational chemical company that produces acrylic tapes for the automotive market

Through a description of the productivity problems experienced by some enterprises, to optimize their respective production lines, results of poor performance or low quality, the following work aims to explain and demonstrate the practical application of the theory of overall equipment effectiveness (OEE) on cold lamination machines in a steel industry . The project, to ensure your goal, is based on structuring a complete planning to increase levels of performance, availability and quality relating to rolling. On completion of the work, will be presented forecasts of future goals for the OEE, to search for continuous improvement and global standards of efficiency, taking into account, the sector the company operates, the history of the laminators, and financial aspects

The pharmaceutical industry was consolidated in Brazil in the 1930s, and since then has become increasingly competitive. Therefore the implementation of the Toyota Production System, which aims to lean production, has become common among companies in the segment. The main efficiency indicator currently used is the Overall Equipment Effectiveness (OEE). This paper intends to, using the fuzzy model DEA-BCC, analyze the efficiency of the production lines of a pharmaceutical company in the Paraíba Valley, compare the values obtained by the model with those calculated by the OEE, identify the most sensitive machines to variation in the data input and develop a ranking of effectiveness between the consumer machinery. After the development, it is shown that the accuracy of the relationship between the two methods is approximately 57% and the line considered the most effective by the Toyota Production System is not the same as the one found by this paper

No setor alimentar, o controlo da qualidade dos produtos e dos processos é uma etapa essencial, uma vez que é por este meio que se avaliam os padrões exigidos, quer a nível de legislação, quer a nível de mercado. O presente trabalho teve, como objetivos principais, o desenvolvimento de um novo produto alimentar com adição de algas, bem como o controlo de qualidade a nível de uma unidade fabril de produção de sumos e polpas naturais, à base de hortofrutícolas. De forma a garantir a qualidade na obtenção de produtos, foi realizado, diariamente, o controlo de entradas dos produtos hortofrutícolas, o acompanhamento de processos nas linhas de produção da fábrica e a análise das amostras de referência. Considerando a tendência e potencial de crescimento apresentados pelo setor das bebidas, nomeadamente dos sumos de fruta naturais, juntamente com a incessante procura por ingredientes naturais ricos em vários nutrientes e com propriedades bioativas, tem-se vindo a registar o lançamento de um número considerável de bebidas inovadoras, onde as macroalgas têm merecido um papel de destaque. Desta forma, procedeu-se à elaboração de dois protótipos, nomeadamente, sumo de framboesa e sumo de espinafres, com a adição do extrato da alga Gelidium corneum, estabilizados através do processo de Hiperpressão a frio, com o intuito de se avaliar o impacto desse extrato nos diferentes parâmetros de qualidade dos sumos. No que respeita aos parâmetros físico-químicos, o pH e teor de sólidos solúveis (TSS) foram avaliados após produção (t0), no tempo intermédio (t15) e no tempo final (t30). A cor foi determinada no t0 e no t30 e os restantes parâmetros, como acidez titulável, quantificação total de polifenóis, capacidade de redução do radical DPPH, teor de proteína bruta, teor de cinzas, teor de minerais e oligoelementos e teor de vitaminas (A, B1, B2 e C) foram avaliados no tempo final (t30). Foram, também, avaliados os parâmetros microbiológicos mais significativos, nomeadamente, microrganismos totais a 30 ˚C, Escherichia coli, Salmonella spp, bolores e leveduras (ao t0, t15 e t30) e realizou-se uma avaliação sensorial ao 29.º dia após produção. Estes sumos apresentaram-se microbiologicamente estáveis, não se tendo verificado crescimento microbiológico durante o período de armazenamento de 30 dias. A análise dos resultados físico-químicos permitiram constatar que a adição do extrato da alga Gelidium corneum aos sumos influenciou as suas características, tendo havido um aumento significativo do pH com a consequente diminuição da acidez titulável e um aumento do teor de sólidos solúveis, em comparação com os sumos controlo. Em relação à avaliação da cor, no caso das amostras de sumos de framboesa, verificou-se que a adição do extrato de algas influenciou o parâmetro a*. No entanto, ambas as amostras permitiram a manutenção deste parâmetro, ao longo do tempo. Quanto ao parâmetro b*, as duas amostras de sumo com algas demonstraram uma evolução mais estável, em relação aos respetivos controlos. No que respeita ao teor em minerais, a adição do extrato da alga demonstrou aumentar os teores de magnésio, sódio, potássio e iodo. Em termos sensoriais, o sumo de framboesa com algas obteve maior aceitação por parte do painel de provadores, podendo-se constatar que o atributo da cor foi o que mostrou maiores variações, entre as duas amostras.

Este projeto surgiu da necessidade de uma empresa da indústria automóvel melhorar o modo de abastecimento das suas várias linhas de produção. Optando por um abastecimento através de comboio logístico, em detrimento do uso de empilhador, indo assim de encontro com as práticas de pensamento lean aplicadas à logística, procurando eliminar o desperdício e aumentar a produtividade de uma ação vital do seu negócio. Nesse sentido, este projeto procurou dar resposta a esse objetivo, consistindo no estudo da situação atual e posterior análise das alterações necessárias a realizar visando a melhoria do abastecimento interno com comboio logístico. O projeto integra diversas reformulações ao nível das linhas de produção, armazém e de todo o planeamento logístico de abastecimento. Ao aplicar as mudanças e os novos planeamentos de abastecimento propostos são esperados resultados de vários ganhos a três grandes níveis: Recursos Humanos, Materiais e Ambientais.
