Item MAPEAMENTO DO FLUXO DE VALOR DE UM PROCESSO PRODUTIVO DE PLACAS ELETRÔNICAS COM USO DA LÓGICA DIFUSA(Instituto de Tecnologia, 2018) ARAÚJO, Caio César Luan Silva; AZEVEDO, Manoel S. Santos; LEITE, Jandecy CabralGlobal competition in the electronics industry has required the optimization of production processes to maintain competitiveness. This study proposes the use of Value Stream Mapping (VSM) combined with Fuzzy Logic to identify and eliminate waste in the production of printed circuit boards at a company in the Manaus Industrial Pole (PIM). VSM allowed mapping the current state of the process, identifying bottlenecks, and designing a future state with improvements. Fuzzy Logic aided in the precise analysis of data, resulting in cost reduction, fewer defects, and optimized production time.Item AVALIAÇÃO DE INDICADORES DE DESEMPENHO DE QUALIDADE NO FORNECIMENTO DE ENERGIA EM USINA TERMELÉTRICA NA CIDADE DE MANAUS(Instituto de Tecnologia, 2018) SOUZA, Stanley Moreira de; LEITE, Jandecy CabralThe study evaluates performance and quality indicators in energy supply at a thermoelectric plant in Manaus, using quality tools to reduce interruptions and avoid regulatory penalties. The research shows significant improvements in availability rates, failure rates, and operational efficiency after implementing methodologies based on tools such as Brainstorming, Cause and Effect Diagram, and Pareto Chart.Item Adequação de Tempos e Métodos em Montagem de Componente para Motocicletas(Instituto de Tecnologia, 2018) YOSHIDA, Thiago Hideki; LEITE, Jandecy CabralThis study proposes actions for the adjustment of times and methods in the assembly line of motorcycle components in an automotive company, using the Lean Production System and the Overall Equipment Effectiveness (OEE) tool. The research demonstrated that the correct application of these methodologies resulted in a 35.3% improvement in process efficiency, in addition to increasing knowledge and application of Lean within the organization. The work highlights the importance of waste elimination and resource optimization for business competitiveness in challenging economic scenarios.Item Aplicação do Controle Estatístico de Processo na Gestão de Qualidade: Estudo de Caso em uma Indústria do Setor Eletrônico Localizada no PIM(Instituto de Tecnologia, 2018) SILVA, José Arcanjo Angelim da; QUARESMA, João Nazareno NonatoThe study investigates how Statistical Process Control (SPC) aids in minimizing rework in the production of ATMs at an electronics industry located in the Manaus Industrial Pole (PIM). Using bibliographic methodologies and a case study, the research mapped the production process, identified bottlenecks, and applied control charts to detect non-conformities. The results showed that SPC is effective in reducing variability and costs associated with poor quality, contributing to continuous improvements in the production process.Item O Efeito da Semi Automatização do Processo de Soldagem MIG sobre Aspectos Ergonômicos e de Produtividade(Instituto de Tecnologia, 2018) FALCÃO, Marcos Maciel; SILVA, José Antonio daThe study evaluates the influence of the semi-automation of a rotating workbench in the MIG welding process, focusing on ergonomic and productivity aspects in a metallurgical industry of the Manaus Industrial Pole. The research shows that the implementation of semi-automation led to significant improvements in operators' quality of life, a reduction in musculoskeletal-related absences, and a 63% increase in daily productivity. The work combines qualitative and quantitative analysis, using field methods and literature review.Item Educação Ambiental no Currículo do Curso de Licenciatura Intercultural Indígena do Instituto Insikiran/UFRRv(Instituto de Tecnologia, 2017) Larisse Livramento dos Santos; Prof. Dr. Cláudio Nahum AlvesThis work aims to demonstrate, through a case study, the application of the 8D tool in a cellular components industry in the city of Manaus - AM. The study details the steps used to adapt the 8D tool according to the company's needs. The research methods are descriptive and exploratory, highlighting relevant information such as selecting process steps and developing plans for applying the 8D tool to improve processes. The study also demonstrates the advantages and benefits achieved with the methodology’s implementation, providing an in-depth view of process adaptations and their role in continuous improvements. The 8D tool is primarily applied using Excel spreadsheets, similar to a checklist, enabling information storage for potential future problems and comparisons with other methodologiesItem Modelo de Simulação Computacional para Balanceamento de Linhas de Produção das Empresas Cerâmicas de São Miguel do Guamá: Um Estudo de Caso(Instituto de Tecnologia, 2013) SILVA, Denilson Costa da; ICHIHARA, Jorge de AraújoThis work presents a computer simulation model to address the production line balancing problem in a red ceramic factory in São Miguel do Guamá. The study includes a literature review on discrete event systems, balancing methods, and modeling and simulation concepts. The methodology follows the method proposed by Chwif (1999), covering design, implementation, and analysis. The developed model describes the current state of the process, identifies bottlenecks, and proposes improvements through scenarios, with the third scenario showing the best results. The main contributions include the practical application of simulation in a local industry and the provision of a tool to enhance production processes.Item Programação Linear: Um Estudo de Caso sobre a Manutenção e o Estoque Ótimo de uma Organização Aérea(Instituto de Tecnologia, 2018) PESSOA, Alexandra Priscila Costa; MAGNO, Rui Nelson OtoniLinear Programming (LP) was applied in stock control of spare parts for an aerial organization, aiming to identify optimal quantities based on financial resource availability. The goal was to reduce costs and improve control, considering minimum, maximum, and current inventory levels. The developed model, using the Solver tool, resulted in savings of R$ 1,044,088.20 by optimizing inventory compared to the established maximum stock. The case study was conducted in an Aerial Organization located in Manaus, Amazonas.Item A Implementação do Sistema de Manufatura Enxuta em uma Montadora de Motocicletas Instalada na Zona Franca de Manaus(Instituto de Tecnologia, 2018) OLIVEIRA, Leandro Correia Santos de; MAGNO, Rui Nelson OtoniThe study presents the implementation of the Lean Manufacturing system in a high-displacement motorcycle manufacturer located in the Manaus Free Trade Zone. Using tools such as 5S, Kaizen, SMED, and line balancing, the research shows significant improvements in productivity, quality, and cost reduction, raising the company's Lean maturity to M=0.74 according to the SAE J4000 standard.Item Otimização do Tempo de Descarga de Vagões Tanque em Terminal de Distribuição de Combustíveis(Instituto de Tecnologia, 2017) SILVA, Jhonatan Ferreira da; QUARESMA, João Nazareno NonatoThe study focuses on optimizing the discharge time of fuel from tank wagons in a distribution terminal, aiming to enhance operational efficiency within a predefined time frame. Hydraulic systems were analyzed, centrifugal pumps and pipelines were sized, and a calculation spreadsheet based on the Darcy-Weisbach formula for head loss was developed. The proposed solution significantly increased the discharged volume, meeting the terminal's demands.
