Gerenciamento de Big Data em plantas industriais

Nowadays the companies generate great amount of data from different sources, however some of them produce more data than they can analyze. Big Data is a set of data that grows very fast, collected several times during a short period of time. This work focus on the importance of the correct management of Big Data in an industrial plant. Through a case study based on a company that belongs to the pulp and paper area, the problems resolutions are going to be presented with the usage of appropriate data management. In the final chapters, the results achieved by the company are discussed, showing how the correct choice of data to be monitored and analyzed brought benefits to the company, also best practices will be recommended for the Big Data management

Melhoria de eficiência de máquinas pela metodologia DMAIC em eventos Kaizen

In a highly competitive and globally integrated market, excellence in production processes has become a survival factor, instead of just a differential point. In this context, companies from various sectors have resorted to philosophies and techniques already established in the literature to improve the efficiency of their production processes. This paper discusses aspects and techniques used to improve the production efficiency of a multinational company that manufactures surgical devices to a global market. Through DMAIC methodology, there were found opportunities to improve machines' efficiency by OEE, an efficiency indicator, in Kaizen Events. A case study was conducted to analyze the methodology and to identify good practices and difficulties along the way

Fatores críticos de sucesso na implementação e gerenciamento do pensamento enxuto: um estudo na manufatura de fitas acrílicas

As a result of the industrial competitiveness increase in recent decades, concern about process improvements has been growing significantly. Lean Thinking principles are being more and more applied in the different sectors of the industry and aim to reduce costs, which can generate satisfactory results for an organization. Besides the application of lean tools on workstations, Lean Thinking seeks cultural change of the employees. Although the concepts of this management philosophy are widely disseminated, many organizations find barriers in their implementation and management. This study seeks to identify and evaluate the critical success factors in the implementation of Lean Thinking based on a qualitative research in the manufacturing environment of a multinational chemical company that produces acrylic tapes for the automotive market

Diretrizes para o gerenciamento de resíduos provenientes de papel na UNESP, câmpus de Rio Claro

As atividades exercidas em uma Instituição acadêmica resultam na formação de diversos tipos de resíduos entre eles um volume considerável daqueles provenientes de celulose, principalmente variedades de papel e papelão, sendo o primeiro utilizado em larga escala para a confecção de objetos para os mais variados fins, de atividades didáticas, usos para fins de limpeza, até documentos. O presente trabalho foi realizado integrado às práticas do projeto PGR (Plano de Gerenciamento de Resíduos) desenvolvido no campus da Unesp de Rio Claro, tendo como objetivo o diagnóstico do gerenciamento dos resíduos de papel e papelão, tais como as práticas de descarte, reciclagem e/ou reutilização vigentes para posterior elaboração de um manual para o gerenciamento ambientalmente correto de tais tipos de resíduos. Para esse levantamento foi elaborado um questionário (Check-list) que foi aplicado nos diferentes setores da UNESP entre Novembro de 2014 e Abril de 2015. A partir desse levantamento preliminar e da quantificação aproximada do montante de resíduos e das porcentagens reutilizadas/recicladas e as descartadas, visou-se propor melhorias no processo de gerenciamento deste tipo de resíduo. O montante de resíduos provenientes de papel gerado nos 50 setores avaliados, sendo 27 do Instituto de Biociências, 21 do Instituto de Geociências e Ciências Exatas e dois de uso comum entre os dois institutos, foi de aproximadamente 190kg de material, embora observado que na maioria das vezes os papéis tenham sido eliminados junto a resíduos de outra natureza, até mesmo orgânicos. Também foram constatadas a proporção de setores que procuram reduzir e reutilizar seus resíduos, sendo que a reutilização de papéis diversos para rascunhos e a utilização de caixas de papelão para o armazenamento de variados objetos foram as práticas mais comumente observadas, sendo apresentadas em maior ou menor grau em 62% dos setores visitados

Implementação do OEE nas máquinas de laminação a frio

Through a description of the productivity problems experienced by some enterprises, to optimize their respective production lines, results of poor performance or low quality, the following work aims to explain and demonstrate the practical application of the theory of overall equipment effectiveness (OEE) on cold lamination machines in a steel industry . The project, to ensure your goal, is based on structuring a complete planning to increase levels of performance, availability and quality relating to rolling. On completion of the work, will be presented forecasts of future goals for the OEE, to search for continuous improvement and global standards of efficiency, taking into account, the sector the company operates, the history of the laminators, and financial aspects

Análise envoltória de dados combinada com a lógica fuzzy em problemas de avaliação de eficiência de máquinas de consumo: um estudo em empresa do segmento farmacêutico

The pharmaceutical industry was consolidated in Brazil in the 1930s, and since then has become increasingly competitive. Therefore the implementation of the Toyota Production System, which aims to lean production, has become common among companies in the segment. The main efficiency indicator currently used is the Overall Equipment Effectiveness (OEE). This paper intends to, using the fuzzy model DEA-BCC, analyze the efficiency of the production lines of a pharmaceutical company in the Paraíba Valley, compare the values obtained by the model with those calculated by the OEE, identify the most sensitive machines to variation in the data input and develop a ranking of effectiveness between the consumer machinery. After the development, it is shown that the accuracy of the relationship between the two methods is approximately 57% and the line considered the most effective by the Toyota Production System is not the same as the one found by this paper

Gerenciamento de resíduos da construção civil: análise e atualização dos estudos realizados na UNESP-FEG para o município de Guaratinguetá

The construction industry is a large consumer of natural resources and one of the largest generators of residues with significant impacts on the environment. Because of the large production of Construction Industry Residues (RCC), it is essential reliable and updated information about generation, composition and classification sources of these residues, especially for management, recycling and final disposal. RCC represent the most part of solid residues generated in a city. In this way, the management of these residues is an issue that is gaining increasing importance in the Brazilian scenario, since the legal and society requirements to internalize the sustainability in the construction process - since the extraction, use, wastage savings, reutilization until the appropriate discard has been increasing in the last years. The present work objective is updating the quantities produced and collected in Guaratinguetá-SP, based on data collected with the municipal administrative entities that act direct or indirectly in the RCC management, elaborate a detailed bibliographic review, with special attention to the graduate works that were realized in FEG about this theme. With this material, scenarios to a better adequacy of the administrative structure to managements RCC activities, as well as was suggested actions to achieve these scenarios
