Item Elaboração de uma matriz de tomada de decisão, com lógica fuzzy, sobre a adoção de tecnologias 4.0 em uma linha de montagem, por meio de gêmeos digitais, com ênfase na mão de obra humana e sistemas robóticos(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) MONTEIRO, Manoel de Assis; GUIMARÃES, Gil EduardoThis study presents the design and analysis of a new production line within the Industry 4.0 framework, emphasizing the interaction between human labor and advanced robotic systems. The research employs digital twin simulation to model and compare two production scenarios: a traditional one, operated exclusively by humans, and an automated system integrating collaborative robots (COBOTs). The methodology uses Plant Simulation software to assess key performance indicators such as productivity, operational costs, worker fatigue, safety, and ergonomic impact. The results highlight significant improvements in production efficiency, cost reduction, better working conditions, and enhanced industrial sustainability. Furthermore, the study discusses the social and economic implications of automation, emphasizing the need for workforce reskilling and adaptation to new technological demands. It is concluded that the strategic integration of robotic systems and digital technologies not only enhances industrial competitiveness but also fosters a safer and more ergonomic working environment, aligned with the trends of smart manufacturing.Item Estudo de caracterização da eficiência produtiva nas indústrias de montagem de eletroeletrônicas do Polo Industrial de Manaus por meio do cálculo do OEE – caso de estudo de automação(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) MONTEIRO, Isabela Zanotto; MARINELLI FILHO, NelsonThis study presents the implementation of Industry 4.0 enabling technologies, with an emphasis on the use of Digital Twins and the automation of OEE (Overall Equipment Effectiveness) calculation, applied to an electronic board assembly line at the Manaus Industrial Complex (PIM). The objective was to develop a solution capable of identifying, in real time, the times and reasons for production stops, aiming to optimize industrial processes and reduce operational costs. The data was collected through IoT sensors installed in the production lines, integrated into a digital platform that virtually replicated the manufacturing plant in a Digital Twin system. The OEE was automatically calculated based on the three main indicators: Availability, Performance, and Quality. Simulations in the virtual environment identified production bottlenecks and allowed predictive actions to avoid failures and optimize machine performance. The results, obtained over 80 days of monitoring, showed progress in production efficiency indicators, with a reduction in unscheduled downtime, dynamic adjustment of production parameters, and improvement in product quality, positively impacting sustainability.Item Análise ergonômica do trabalho (AET) em linha de inserção manual de produção industrial no segmento eletroeletronico(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-12-10) FERNANDES, Raulchelison Tavares; BEZERRA, Roberval Monteiro; http://lattes.cnpq.br/0466572603004690The ergonomic analysis of work (EAW) has as its principle to identify and try to prevent possible diseases that develop slowly due to repetitive movements, unfavorable postures, furniture without comfort and visual discomfort, causing for the organization the loss of productivity, employee dissatisfaction, and increased costs. The inadequate working environment and furniture can also lead to reduced productivity in companies, because if not adjusted to biotypes can lead to the occurrence of occupational diseases. One of the great challenges of ergonomics applied to work is to design or adapt workstations and tools to the morphological diversity of the population. The accurate analysis of the various segments is done according to the techniques of anthropometry, which is the study of the physical measurements of the human body. This research aimed to "apply the ergonomic analysis of work (EAW) in the production line of a company in the electro-electronic segment to promote improvements in the workplace aiming at the quality of life, well-being, and safety of the employees". In the study methodology, a population survey of the company's biotypes was carried out through anthropometric evaluation; the human body movements were analyzed, with emphasis on the upper limbs, according to the conditions of their workstation; ergonomic concepts were implemented in the production line; the workstations were adapted to the employees; and, finally, the results of productivity were monitored, followed up, and compared after the ergonomic improvements were implemented. To analyze the results of this research, a sampling of 375 employees was carried out with emphasis on the manual insertion production line. The anthropometric analysis showed that there is a difference between male and female biotypes. With the female more concentrated around the mean and the male presenting a larger tail of the distribution. The ergonomic analysis of the work identified the need for adaptation, alteration and changes in the workstations that start in the equipment permeating with the improvement of the posture of the employees that operate in the production lines. After the implementation of the improvements, the ex-post analysis showed that the company's proposed targets for productivity, quality, and absenteeism were met, with averages of 780.2 units/manhour, 281.4 pieces/million, and 1.8%, respectively.
