(Universidade Federal do Pará, 2020-02-12) DIMARIO, Raphael Kinzu; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785; https://orcid.org/0000-0001-9365-7498
The target of this research is highlight the application of Lean Manufacturing tools in motorcycle assembly process. Productivity increase, line stoppage control and 5S methodology are expected to be improved. Specifically, the entire production flow was mapped and Lean tools were chosen to be implemented in the shop floor. Also, key performance indicators were used as the way to show and share all improvements and benefits reached. Lean manufacturing is a production system focused to identify and maximize the added value of the products based on wastes reduction including value stream map, standardization and 5S.The project was developed starting from the literature research and case study. Direct observation in the shop floor collecting all data and analysis of them made part of this study. Regarding data, were collected the cycle time of all process, material flow and 5S status of the area. Significant achievements were reached during and in the end of this project. It was increased 15% of 5S score. Line stoppage was reduced by 52% with important actions like standardization and homologation of new method of material control. Significant increase of 37.5% in productivity and capacity raised the company to the next level. As indirect result is worth to mention a reduction of R$9,900/year in extra shipments due to material control improvement.

Implantação de um novo layout de uma linha de montagem de motocicletas estruturados a partir da metodologia MASP e ferramentas Lean manufacturing
(Universidade Federal do Pará, 2021-05-04) OLIVEIRA, Edyones Barros de; MAGNO, Rui Nelson Otoni; http://lattes.cnpq.br/9017163598972975
This study aims to approach the implementation of a new layout of manufacturing process for high displacement motorcycles using the MASP methodology and Lean Manufacturing tools as a facilitator to adapt to the market oscillation. The research was carried out in a motorcycle industry located in the Free Trade Zone of Manaus, using the PDCA method (Plan, Do, Check, Action) for the feasibility after SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) in which the focus of actions of the project was defined. As a result, benefits were presented, such as: flexibility to increase production capacity due to the new layout arrangement and 67% reduction of Work In Process that made 25% of the total industrial area viable; versatility in the assembly process due to increased training of operators to produce all models; 5,5% reduction of the operator quantity keeping the same productive capacity; a reduction of at least 25% in the investment needed to implement new products, reaching up to 60% depending on the motorcycle in question, enabling the approval of the launch of four models in the last six months and avoiding an increase of 51.25% in value the asset chart; annual reduction of R$ 80,000.00 in costs with spare parts and preventive maintenance service; 15% reduction in electricity consumption; and a 5% decrease in line stoppage due to the limitation to change the production plan. With that, it provided greater brand competitiveness in the Brazilian market even when compared to other brands in thex same segment that have already presented studies of process optimization focused on the Lean Production principle but limited to the manufacturing benefits.

Implantação do lean manufacturing na gestão de manutenção no terminal portuário ponta da madeira – TPPM: estudo de caso nos processos de planejamento, programação e controle (PPCM)
(Universidade Federal do Pará, 2021-09-02) FERREIRA, Maryclea Mourão Furtado; BRAGA, Eduardo de Magalhães; http://lattes.cnpq.br/4783553888547500
Na atualidade, estas demandas foram ampliadas e, além de custo, qualidade, velocidade de entrega e flexibilidade, identifica-se um mercado que passa a cobrar pela redução dos impactos ambientais gerados pelos produtos e processos. Tendo como problema os fatores que ocasionam a perda de estabilidade, pode-se elencar as falhas ou quebras dos equipamentos operacionais e estes podem vir a decorrer por vários motivos. Com o objetivo geral de aplicar ferramentas do Lean em um processo de PPCM. Essa pesquisa adotou o estudo de caso para seu desenvolvimento, o estudo de caso indica princípios e regras que devem ser observados durante o processo de investigação. Os resultados principais alcançados foram: o aumento de 5 pontos percentuais (pp) correspondente a 7% na disponibilidade física dos ativos e de 4pp corresponde a 5% na disponibilidade intrínseca, além de ganhos nos indicadores de processos, com aumento de 37pp equivalente a 77% para aderência as manutenções sistemáticas e 37pp equivalente a 25% no indicador de aderência a programação, o que demonstram a eficiência do modelo proposto. Comprovando a importância da aplicação do pensamento enxuto por meio da melhora de alguns indicadores selecionados e consequentemente melhoria nos processos de manutenção.

Implementação do lean manufacturing em uma oficina de recuperação de componentes localizada em uma empresa do setor de mineração - São Luís - MA

The success of a company in a competitive and globalized market is in the ability to identify and eliminate waste, reduce costs, add value to the customer, stabilize, innovate and continuously improve its processes. This justifies the performance of work in which with the growing scarcity of resources and the need to improve maintenance processes, it is sought to plan and improve activities in order to obtain a quality product satisfying the company's customers and employees, the more efficient is the planning and scheduling of maintenance, the lower the rates of rework and unscheduled maintenance. The objectives demonstrate the application of Lean Manufacturing tools in a Component Recovery Workshop located at the Ponta da Madeira Port Terminal -TPPM in São Luís in Maranhão. Among the methodologies addressed, this research has a qualitative character because it is centered on the reality of the company, in addition to being bibliographic, documentary because existing data are used, the data collected are predominantly descriptive, the researcher's interest when studying a particular problem is to verify how it manifests itself in daily activities, procedures and interactions, data analysis tends to follow an inductive process. The results obtained thus evidencing continuous improvement works aimed at operational excellence, training of several teams in various processes, elimination of waste and results aimed at financial gain. There were also defenses of new investments for the Workshop with new technologies positively impacting productivity

Método para monitoramento de desempenho em tempo real e a cadeia de ajuda como apoio a estratégia da manufatura enxuta
(Universidade Federal do Pará, 2022-02-22) SANTOS, Tamires Priscila Souza dos; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317
With the advancement of technologies, the market increasingly drives competitiveness, where new performance standards are imposed, generating a series of challenges for companies, such as the need for paradigm shifts in relation to many things, but mainly productive process control. The rapid absorption of external elements, new projects, rotating teams, demand fluctuation and other variables, makes companies to create and innovate mechanisms to adapt themselves and apply quick respond to the findings and issues. The survival key for any production process is low cost and high quality. To meet this expectation, online controls are implemented to block manufacturing issues that can go out of control if not detected on time. The Lean Manufacturing strategy has helped in thisbattle, however, some of the proposed tools, such as production control methods based on self-control by the operators themselves, in general employing management boards in sight at the workstations, are often not enough to ensure the accuracy of information to identify the root causes of problems in companies where the practice of continuous improvement by problem identification, analysis and solution is not as strong. This work proposes a method of implementing real-time production performance monitoring within the Lean Manufacturing strategy that, with the creation of a Help Chain, that when effectively triggered by an online system, drives the rapid solution of problems. Real-time monitoring of production performance creates favorable conditions for verifying the effectiveness of any improvement implemented and for permanently monitoring the results. The case study of the implementation of the proposed method of monitoring the real-time performance of manufacturing of a company in the electronics industry will be reported.
