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.

With the reference this scenario, this work brings a methodology of analysis of the risk of R&DI (Research, Development and Innovation) projects, using the fuzzy mathematical model, developed in an organization whose core business is the research and development of new technologies. This analysis occurs through the development of linguistic variables (input), with the aim of identifying measure the degree of risk in projects. After the determination of the guidelines to be followed, it was possible to obtain results that demonstrate that the developed fuzzy model can assist in the identification and prioritization of the variables that increase the degree of risk of technologies development projects.Item A utilização de um modelo fuzzy integrado à gestão de estoque em empresas do ramo eletroeletrônico(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-08-02) CARVALHO, Monteiro, Adler Matos; NASCIMENTO, Manoel Henrique Reis; http://lattes.cnpq.br/0850846128967798Inventory management is a practice of fundamental importance for the success of companies in the most varied segments. Companies that operate with low levels of profitability depend on efficient inventory management, under penalty of losing competitiveness. Efficient inventory maintenance is not characterized by the existence of large batches of products for prompt customer service or, on the contrary, by the lack of inventories in an attempt to minimize maintenance costs. Inventories must be managed in a balanced way to ensure an adequate level of service to customers and generate profits. This work aimed to develop a Fuzzy model for stock management of an organization, to reduce the lack of material in stock, resulting from the "lead time". The work is justified by the importance of having a management monitoring the control of inventory costs, which includes the expenses resulting from the lack of items, the costs related to the replacement of the stock, and the expenses of a stopped stock. To accomplish this, it was necessary to map the Material Purchasing Process and thus identify which were the most significant variables in inventory management. The use of Fuzzy Logic, idealized for a model like this, is to reach an inventory level close to zero, immediately before physical replacement, thus minimizing unnecessary costs. Therefore, experimental research aims to manipulate and control the research variables. The application of the developed model shows that the evaluation of Inventory Management through the Need for Replacement of Input and Type of Transport to be used through the fuzzy methodology proved to be viable to assist the desired observations, allowing to understand the impact of each linguistic variable in the research result, pointing out how company X can use the information obtained to improve the structure of its Logistics Process, thus reducing the lack of material in stock due to the lead time.Item Uso de ferramentas computacionais e de qualidade na melhoria de design de monitores de LCD(Instituto de Tecnologia e Educação Galileo da Amazônia, 2022-03-07) SILVA, Ronildo Souza da; LEITE, Jandecy Cabral; http://lattes.cnpq.br/7279183940171317Companies all over the world aim to launch a considerable amount of new products every year. During this process, project failures and design problems are often detected. In this context, this study aims to scientifically explore the events that occurred during the implementation of a new LCD (Liquid Crystal Display) monitor product, where its functionality, appearance, quality, and cost are considered satisfactory; however, its design had a negative impact on the mass production process and presented a great need for improvement. The research then sought to understand the causes of the problem and apply some solutions, especially for the biggest defect found in the project: infiltration of adhesive inside the joystick button actuation mechanism. The applied methodology was developed through action research, which meant an active role in the analysis of the problem and development of solutions within the research environment and used quality tools (PDCA, Ishikawa and Kaizen) and parameters of the fuzzy logic tools (linguistic variables, fuzzyfication, Inference rules and defuzzification). As the result, the organization obtained several benefits, such as reducing the defect rate from 20% to less than 3%, reducing costs with spare parts and repair service, and increasing quality and productivity indicators. There was also an impact on product costs, with probable savings with the implementation of the improvement estimated to be around R$ 16 million in a six-month period. Considering these factors, this work produced the desired effects on its object of study in a satisfactory way.
