Item Proposta de um algoritmo de detecção de falhas com lógica fuzzy para otimização de motores elétricos em processos de fundição de alumínio(Instituto de Tecnologia e Educação Galileo da Amazônia, 2024) SILVA, Lenildo Marcos da Mota; BRITO JUNIOR, Jorge de AlmeidaThis study proposes the development of a fault detection system based on fuzzy logic to optimize electric motors in aluminum casting processes. The theme is grounded in the need to enhance efficiency and operational continuity in the casting industry, minimizing unplanned downtime and maintenance costs. The primary objective is to create a fuzzy control model that enables real-time monitoring of critical variables, such as temperature, pressure, and electric current, to facilitate predictive fault detection. Methodologically, operational scenario simulations were conducted to evaluate the model’s performance under adverse conditions, including overload and overheating, with validation through experimental testing. Results indicate that the proposed fuzzy system accurately identifies anomalies and issues preventive alerts, extending motor lifespan and reducing downtime. It is concluded that the model can be integrated with supervisory systems like SCADA, enhancing predictive maintenance and operational efficiency. This technological solution shows promise for the aluminum casting industry and potential applications in other industrial sectors.Item Algoritmo de Detecção de Falhas com Lógica Fuzzy para Otimização de Motores Elétricos (ADFLFOM)(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) NASCIMENTO, Manoel Henrique Reis; LEITE, Jandecy CabralThis document certifies the registration of the software Fault Detection Algorithm with Fuzzy Logic for Electric Motor Optimization (ADFLFOM), developed in the Python programming language.

With this, the research conducted in a watch factory X, aimed to analyze the factors that contribute to the performance and analysis of an international supplier. In view of this, to reach this objective, it was necessary to raise the rates of rejects in the process of inspection in receipt and assembly, as well as the process of service term of replacement in reject, aiming to evaluate the supplier's performance. The need to perform this analysis arose through the experience of one of the members of the group, who works in the company, reason why this dissertation can contribute to maximize the decision making of managers in relation to the approval or non-accreditation of suppliers for the production of watches. The quantitative approach aims to measure the variables, as the procedure for data collection was carried out through excel spreadsheet documents copied from the SAP program. At the end of this research, improvement actions were suggested to the company according to the application of the supplier evaluation by the fuzzy logic method. The results achieved in the dissertation, obtains substantiation through the evaluation method used, and thus, minimize the losses that can generate significant losses to the process of waiting for information copilation for decision making.Item Aplicação da lógica fuzzy na definição da resistência à compressão de caixas de papéis ondulados(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-09-16) LIMA, Vagner Rodrigues; LIMA, Moysés Mendes de; http://lattes.cnpq.br/8329412238374484Corrugated paper packaging, commonly called cardboard packaging, stands out among the most used in industry and commerce in general. These packages have established themselves as the preferred resource when it comes to storing and transporting products, this is fundamentally due to their low cost. Furthermore, the packaging box is fully recyclable and perfectly meets the environmental appeal and awareness of using less polluting and more sustainable raw material. Packing box damage occurs mostly in the storage or transport of the finished product. One of the main causes for these failures is directly linked to the definition compressive strength that the packaging box must withstand throughout its life cycle. In this research, a computational model based on Fuzzy logic is proposed to classify the compressive strength of the designed packaging box as being: inadequate, good, adequate. Always taking into account that the higher the value of the compressive strength, the lower the cost of the box. As a support tool, two methods well known among packaging box designers were used, the calculation of compressive strength using Mckee’s formula and the method of calculating compressive strength using static stacking. The approach proved to be effective, since it was possible to validate the classification of the with the use of Fuzzy logic.Item Otimização do processo de fabricação de embalagens de papelão com lógica fuzzy(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-08-24) FERNANDES, Everson Lima; ALENCAR, David Barbosa de; http://lattes.cnpq.br/4890967546423188This study arose from the need to meet the demand for manufacturing monitors at a lower cost than initially budgeted, with the assembly of the new corrugated cardboard packaging, complying with the requirements established by the client DELL and with a reduced staff of 42 employees to a maximum of 08 people in the assembly process.
