Item Acesso aberto (Open Access) Uma abordagem heurística para os problemas de horários educacionais(Universidade Federal do Pará, 2020-12-15) REIS, Williams Sousa dos; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785With each new school term, educational institutions have the hard work of allocating their class schedules, the problem implies in allocating time intervals and resources to activities, in such a way that they satisfy the restrictions imposed in the best possible way. This is a problem considered difficult to solve from the point of view of computational complexity theory. With this in mind, this work aims to develop a tool that can automate the time allocation process carried out by the Institute of Biodiversity and Forests (IBEF) at the Federal University of Western Pará (UFOPA), presenting a proposal based on the meta-heuristic known as genetic algorithm (AG). This proposal is submitted to several experiments with real data from that institution and the results are fully satisfactory, evidenced by overcoming the restrictions imposed by the problem in an acceptable computational time, bringing some advantages with the automation of the process, such as: reduction in time development of time allocation; and better reallocation and use of physical and human resources.Item Acesso aberto (Open Access) Análise da viabilidade econômico-financeira nos processos de importação para pesquisa científica e tecnológica em uma instituição de ensino federal(Universidade Federal do Pará, 2020-12-11) DOSSENA, Sandra Maria; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785Purchases through imports, at federal institutes, have been a challenging task, where the objective of this work is to demonstrate whether there is a financial advantage in importing goods and inputs for scientific and technological research, in these institutes. The campus chosen to support the analyzes was the Campus Manaus Distrito Industrial, from Instituto Federal de Educação, Ciência e Tecnologia do Amazonas. For this, the methodology used consisted of applied kind, as for the objectives it was descriptive, with quali-quantitative approach and based on documentary research.

Through the selection and analysis of all purchases made through imports (ten import processes studied), in that period, the a study showed savings of R$ 336,298.97, representing approximately 44% of financial savings in relation to purchases in national marketItem Acesso aberto (Open Access) Aplicação da matriz Swot com auxílio da lógica fuzzy para definições de propriedades ao planejamento estratégico de uma empresa(Universidade Federal do Pará, 2019-05-07) FERREIRA, Manuela Jardim de Paiva; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785; https://orcid.org/0000-0001-9365-7498; MACÊDO, Emanuel Negrão; http://lattes.cnpq.br/8718370108324505In order to seek improvement in procedures and increase the competitive market differential, organizations aim to develop programs and planning that assist the needs of companies. Therefore, this research presents a method capable of assisting in the elaboration of internal and external analysis of a company, which is the SWOT Matrix, to provide a self-diagnosis, key points of the organization such as: Weaknesses, Forces, Opportunities and Threats, that interconnected with Fuzzy Logic allows a holistic view of the points that need attention. The methodology used was the application of questionnaires, direct observation and data collection, developed in the form of a case study in a construction material company. The application of the organizational diagnosis is performed through forms, which are compiled and demonstrated through the Fuzzy graph. Then the internal and external environments are analyzed, and the graph of the critical areas is assembled. In this study, the results pointed out that the critical areas were: Marketing, Physical Environment and Procedures, which need to be adapted to the needs of the company. Thus, a new strategic plan was applied involving methods necessary for the success of the critical areas that consequently brought about improvements to the company as a whole, which has undergone relevant modifications. Thus, it was verified that one must be awabhre of the necessary changes in the newix scenarios and in the new times that the market itself in which the company is inserted demands.Item Acesso aberto (Open Access) Aplicação de ferramentas de manufatura enxuta em processo de montagem de motocicletas no Pólo Industrial de Manaus(Universidade Federal do Pará, 2020-02-12) DIMARIO, Raphael Kinzu; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785; https://orcid.org/0000-0001-9365-7498The 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.Item Acesso aberto (Open Access) Avaliação da maturidade em instituição pública: utilizando gerenciamento e monitoramento de redes com software livre(Universidade Federal do Pará, 2020-02-12) MOREIRA, Sandro Figueira; QUARESMA, João Nazareno Nonato; http://lattes.cnpq.br/7826389991864785; https://orcid.org/0000-0001-9365-7498; ESTUMANO, Diego Cardoso; http://lattes.cnpq.br/5521162828533153; https://orcid.org/0000-0003-4318-4455In this case study, we used the ABNT ISO / IEC 14598-6 tool to measure the quality of the software applied in the IT area, of a federal research and education institute, regarding the management system. and network asset monitoring, based on open source ZABBIX software.
