Item Acesso aberto (Open Access) Adaptação da metodologia da integração contínua na estratégia de desenvolvimento de produtos de software em empresas de economia mista de tecnologia – estudo de caso(Universidade Federal do Pará, 2021-09-22) SOUZA, Renato Borges de; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798The continuous integration methodology is a broad field that deals with the availability and publication of system codes, which aims to help associations to accelerate their development and delivery of software resources, without compromising quality. This approach becomes extremely important for speed in product deliveries. The main focus of this article is to promote the adaptation of this methodology by aligning it with the software product development strategy, in order to improve organizational results, through waste reduction, with knowledge of the end-to-end process. A case study was proposed to illustrate an execution of this process. Where, first, the mapping and analysis of the system development process and current portfolio management in the company was carried out, identifying its problems, and then a future process design was proposed, promoting the integration between the parts. This process will help the company to deliver products that fit the organizational strategy.Item Acesso aberto (Open Access) Desenvolver um modelo de inferência fuzzy para medir a qualidade dos processos do gerenciamento de projetos em uma instituição do terceiro setor(Universidade Federal do Pará, 2021-09-22) SOUZA, Juliana Câmara de; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798The contemporary business environment seeks continuous improvement to remain competitive in the market, as customers increasingly demand quality products or services. In this perspective, this paper presents a methodology aimed at evaluating the quality of processes in the project management sector in a Third Sector Organization, based on the Fuzzy mathematical model. For this, linguistic variables (input) were developed according to information obtained from company Y, which enabled the application of the Fuzzy Logic method, in order to determine the output variable, which in this case is quality. After determining the rules, it was possible to obtain results that show that the developed fuzzy model has the potential to help improve the quality of processesItem Acesso aberto (Open Access) Inferência fuzzy para avaliação da maturidade em gerenciamento de projetos baseado no modelo MMGP(Universidade Federal do Pará, 2020-11-16) MACAMBIRA, Harold Maia; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798This research presents a fuzzy inference model for evaluation of maturity in project management based on the MMGP model. Improving the accuracy of any assessment makes your result more assertive by directing initiatives correctly. You cannot manage what is not being used, and its measurement must be accurate so that the actions can be aligned with the real need, thus obtaining better results. This work seeks to improve the result of the analysis proposed by Darcy Prado [Prado 2000], where he conducts a questionnaire to score the level of maturity in project management of the organization. In view of the result of the questionnaire presented by the MMGP model, fuzzy inference is applied and the results are presented objectively, proving the best accuracy of the results. Both models, MMGP and MMGP+Fuzzy, were applied in one Company obtaining similar results, however, for the fuzzy model smoothing and accurateing the response, instead of the binary model proposed by the MMGP.Item Acesso aberto (Open Access) Lógica fuzzy aplicada nas medidas de apoio à tomada de decisões do sistema de gerenciamento de produção de embalagens plásticas(Universidade Federal do Pará, 2019-06-05) SANTOS, Maycon Bentes dos; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798Currently the automation through decision support systems, plays a fundamental role in the productive chain, from small to large companies, the present study proposes a fuzzy inference model, in the support in the decision measures of the production management system of plastic packaging factory. Analyzing the distinctions of forceful form of each step that end up influencing in the process, and aiming to adapt to the requests of the clients. Using as principle for the proposed system the adequacy of shifts using the maximum output that the factory has. MatLab software was used to treat the data, thus adjusting the variables, which were selected due to their degree of influence in the cycle because they are variables that determine the order of the product's manufacturing, they are: delivery period, quantity required, process production and the number of shifts that will be required to produce a given product, observing with the use of this tool an improvement in the management of shifts, which reduced unnecessary costs and a good understanding in the production cycle in relation to the characteristics of the orders.Item Acesso aberto (Open Access) Metodologia de aterramento em linha de transmissão em ocorrência alternada 550 KV na Amazônia – um estudo de caso(Universidade Federal do Pará, 2021-04-07) CARVALHO, Franklin Barbosa de; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798Lightning strikes are of great importance for the electricity sector, being frequently responsible for disconnections of transmission lines, which can trigger a sequence of events that lead to the interconnected electrical system to collapse. The objective of this work is to propose a new methodology to correct the grounding resistances of the LT Oriximiná / Silves CD 550kV electric power transmission line in the Amazon aiming to reduce the occurrences of shutdown by disruptive return discharge, or backflashover, mitigating the damages caused to the system. electrical, considering the implementation cost factors, environmental technical feasibility, abruptness of the solution for other line structures, percentage of implementation reduction, it was concluded that the most adequate solution to implement a more robust grounding solution in the towers of the line transmission is the 03 solution tested on the 585 tower with a 66.98% reduction.Item Acesso aberto (Open Access) Modelo de inferência Fuzzy para avaliação da análise Swot como apoio na tomada de decisão organizacional(Universidade Federal do Pará, 2021-06-11) NOGUEIRA, Enyleide Lima; NASCIMENTO, Manoel Henrique Reis; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798Current market conditions require organizations to understand the business environment in order to achieve strategic planning and decision-making processes. An organization's competitive advantage is associated with an understanding of how to determine the potential of these companies when examining internal and external conditions (insertions) and the effort to meet customer needs. Among the many tools that contribute to this understanding, the SWOT analysis stands out, which can help organizations better understand the internal and external environment and formulate strategic plans in a collaborative way. This work aimed to implement an evaluation model for SWOT analysis using fuzzy inference methods. The adopted methodology started from a survey on the internal and external characteristics of the organization, definition of the linguistic criteria of the SWOT matrix, correlation between the variables found and elaboration of the fuzzy inference system for crossing the entries. The approach proposed by the Fuzzy Inference model for the SWOT matrix proved to be simplified and efficient for a better collection of information that helps in the prediction of the future environment, enabling reasoned strategies resulting from the model presented.Item Acesso aberto (Open Access) Previsão de risco de atraso na execução de obras públicas por meio da lógica fuzzy: estudo de caso na cidade de Manaus(Universidade Federal do Pará, 2021-09-22) VALENTE, Andrey Willen Nunes; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798The occurrence of delays in public constructions is not uncommon, as their execution deadlines are often extrapolated, even though such deadlines are obtained through preliminary technical studies. The causes that originate such delays are varied, ranging from rainfall to increases in quantities of existing services or increases in new services. In this research, we sought to obtain a procedure, using fuzzy logic, to predict the risk of delay that some variables may cause in the period of execution of the work, allowing a public administration or a contracted company to adopt measures that they consider essential for mitigation of this delay. Initially, documentary and bibliographic research was carried out in order to identify the causes that most contribute to the occurrence of delays in the works. Once these causes were identified, the construction of the fuzzy inference system was started, with six of the most significant causes identified in the research being considered as linguistic variables, namely: the hiring factor, which corresponds to the quotient between the value of the proposal of the company and the amount budgeted by the administration; the value of the work, which is the value of the contract for the work; the executive design, which are the engineering designs used; the change in quantities, which are changes in the quantities of existing services or addition of new services; authorization from public agencies, which corresponds to the permission or support of any public agency or public company for the execution of the work; and the rain. For simulation of the created fuzzy inference system, real data from four public works were entered, and the answers of this simulation were satisfactory, due to the fact that they are confirmed by the documentation of the respective works. It is concluded that the system proved to be useful, as it was possible to predict the risk of delay in the execution of public works in the city of Manaus, and it can be used by both the public administration and the contractor to mitigate the causes of delays in the execution of public works.Item Acesso aberto (Open Access) Proposta de avaliação de riscos em prensas hidráulicas com lógica Fuzzy(Universidade Federal do Pará, 2021-04-07) SLUCE, Patrícia; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798The aim of this study was to evaluate the safety level of industrial machines, in particular hydraulic press. The dissertation used hydraulic presses as the object of study. The research instruments used were machine safety analyzes based on normative items preestablished in ABNT NBR: 12100, possible accidents that these machineries can cause. The results show that hydraulic presses cause many accidents, in some situations dying. Through Annex B of ABNT NBR 14153: 2013, there are 4 risk categories for machinery, the greater the degree of risk, the more unsafe the machine is. The appraiser's experience is very important to analyze the machine and reach the level of risk level before and after the adjustment. Finally, it appears that the machine analyzed in this study was at risk level 3, after analysis and adaptations the same machine was at risk level 1, totally acceptable to maintain the operator's safety level.Item Acesso aberto (Open Access) Segurança no trabalho: especificação de um modelo de inferência fuzzy para avaliação do agente calor(Universidade Federal do Pará, 2021-08-02) VIEIRA, Alex Sander Záu; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798This article presents a study that consists of a fuzzy inference model specification for the evaluation of heat agents. The structure of model fuzzy used were inputs measured temperature and metabolic rate, while the output was work environment condition that could be salubrious or insalubrious.

As a result, the proposed model got the correct classification of work environment conditions with pertinent results according to current legislation and technical expertise.Item Acesso aberto (Open Access) Sistema semiautomatizado para redução do desperdício de ração e otimização do conforto térmico no processo de criação avícola de pequenos produtores do interior da região Amazônica(Universidade Federal do Pará, 2021-08-02) BEZERRA, Rômulo Cavalcante; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798In the Amazon region, the reality of the conventional laying poultry production chain consists of farms with structures that are inferior to those in other regions, with a massive presence of small poultry farmers, without a water, food and air conditioning automation system. The need for improvements in the poultry process that the small producer needs to produce can be linked to the relationship of implementing technology for monitoring equipment or systems. Therefore, the motivation of this study was the creation of a semi-automated system to optimize the thermal comfort of birds and red3uce feed waste in the laying poultry production process for small producers in the interior of the Amazon region in order to reduce mortality and maximize the profit. The methodology designated for the construction of this research was based on the nature of applied research, with a view to the qualitative-quantitative approach, through technical procedures of a case study. After assembly of the semi-automated system for feeding, adding the total savings for feed consumption would be 1964.20 kg of feed, in reais it would be R$ 7,856.80. And for the ambiance system, we have savings on the energy bill of 60.94 reais a month and 731.31 reais a year. The semi-automated systems suggested for small poultry farmers in the Amazon region theoretically fulfill their objective, both for the improvement of waste and for the provision of animal welfare and increased profitability.
