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

Hymenoptera é uma das maiores ordens de insetos, com mais de 130 mil espécies descritas. Dentre as principais famílias destacam-se: Formicidae, Apidae e Vespidae, sendo que a última inclui a grande diversidade de vespas sociais presentes no Brasil. Este grupo tem grande importância no controle biológico de outras populações, como predadores ou controladores de pragas agrícolas, além de serem visitantes florais e polinizadores ocasionais. Sendo assim, o presente estudo consiste em um inventário das vespas sociais da Floresta Estadual Edmundo Navarro de Andrade (FEENA) em Rio Claro, SP, que possibilitou a comparação entre diferentes métodos de coleta empregados na captura de vespas sociais (coleta ativa e armadilhas atrativas em diferentes estratos na vegetação) e a comparação da fauna atual com um inventário realizado a mais de 30 anos na mesma localidade. Os dados foram coletados em diferentes estratos da vegetação utilizando armadilhas de garrafa PET contendo líquido atrativo (uma próximo ao solo, outra a 1,5 m de altura e a outra acima de 3 m na copa das árvores), e através de técnicas de coletas ativa com auxílio de redes entomológicas. Foram realizadas quatro coletas no decorrer de um ano, uma em cada estação. A riqueza das espécies do atual inventário foi comparada com a de Rodrigues & Machado (1982) e observou-se uma diminuição do número de espécies ao longo dos anos, de 32 para 21, sendo que 17 espécies foram amostradas em ambos os inventários. Dentre as armadilhas atrativas, houve diferença entre os estratos, sendo que as armadilhas de dossel mostraram ser de grande importância, pois capturaram 41,8% dos indivíduos e ainda apresentaram quatro espécies capturadas exclusivamente neste estrato. A técnica de coleta ativa com redes entomológicas também foi relevante, sendo responsável pela coleta de 93,75% dos indivíduos da tribo Mischocyttarini

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

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

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses

With the Big Data development and the growth of cloud computing and Internet of Things, data centers have been multiplying in Brazil and the rest of the world. Designing and running this sites in an efficient way has become a necessary challenge and to do so, it's essential a better understanding of its infrastructure. Thus, this paper presents a bibliography study using technical concepts in order to understand the specific needs related to this environment and the best forms address them. It discusses the data center infrastructure main systems, methods to improve their energy efficiency and their future trends
