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

Proposta de metodologia para gestão de produção, visando redução no consumo de energia elétrica em uma unidade fabril do setor de bens de consumo

Actually the energy efficiency is making more space in the industry, due to the search for the sustainability, the electrical energy costs reduction, the goals achievement or the efficiency of production processes. In consumer goods industries, such a beverage industry, as the work is based, the productivity is directly related to the electrical energy consumption. The development of methodologies and/or routines, in addition to some tools which allow to align more efficiently these two aspects (production and consumption of electrical energy), in the viewpoint of the Energy Conservation, is very important. In this case, the study will show the Plant Modulation concepts, a production management methodology, based in some factors related to the productive process, installed equipment, production supplies and energy cost. The proposed methodology was implanted in a plant along 2015 and show the results, in face to confirm its efficiency. Finally, in this study, it was shown the capacity of Plant Modulation to positively impact in the energy efficiency inside a big industry

Estudo para determinação de uma metodologia para o ensaio de arrancamento que avalia aderência aço/concreto

This work talks about the importance of the steel adhesion to concrete, reinforced concrete structures, their testing and forms of measurement used and how the results are used in the structural design, which uses as a reference the NBR 6118 and NBR 7480. It also deals with the importance of a reliable assessment, discussing failures that the test used, NBR 7477, features in specific circumstances, as discussed under the EC-094. It also presents an initial proposal for simplified pullout test, which aims to analyze the grip on steel bars with diameter less than 10 mm, which results when used standardized testing by ABNT NBT 7477, has shown excessive variability, the main criticism of the trial today used without distinction to be established thick or thin bars. The proposal also presented methodology is in the consolidation phase, given the time and the volume of necessary tests. For this reason it is not possible to make a comparison between the values obtained and the results of the test used on the basis of the standard in force, this can only be done once the front with a continuation of this work

O processo histórico de disciplinarização da Metodologia do Ensino de Matemática

Desde as primeiras décadas do século XX, foi constatada nos currículos dos cursos de formação de professores a existência de uma disciplina cuja constituição, funcionamento e objetivos têm como pressuposto ensinar a ensinar a matemática. Historicamente, a disciplina Metodologia do Ensino de Matemática tem aparecido nos cursos de Licenciatura em Matemática com distintas denominações. Ao longo dessas mudanças, os pressupostos e as características dessa disciplina foram se modificando. Tomando como metodologia de pesquisa a análise documental e a história oral, e como referencial teórico os estudos de André Chervel (1990), este trabalho teve como objetivo compreender o processo histórico de disciplinarização da Metodologia do Ensino de Matemática em cursos de licenciatura em Matemática de instituições públicas de ensino superior do estado de São Paulo (USP, UNICAMP e UNESP-Rio Claro), buscando conhecer a gênese e o desenvolvimento histórico da disciplina, identificando conteúdos e métodos propostos bem como as mudanças pelas quais passou a disciplina.

Metodologia de construção de um painel de indicadores para o monitoramento e a avaliação da gestão do SUS

Este estudo teve como objetivo desenvolver uma metodologia de construção de um Painel de Monitoramento e Avaliação da Gestão do Sistema Único de Saúde (SUS). O processo participativo utilizado e a sistematização realizada permitiram identificar uma estratégia efetiva para a construção de instrumentos de gestão em parceria entre pesquisadores, instituições acadêmicas e gestores do SUS. A sistematização final do Painel selecionou indicadores da gestão do SUS em termos de Demandas, Insumos, Processos, Produtos e Resultados de forma a disponibilizar um instrumento simples, ágil e útil para a avaliação em qualquer instância de gestão e mais transparente e de mais fácil comunicação com todos os interessados na tomada de decisão. Tomar a gestão do SUS como objeto destes processos e práticas em seus aspectos normativos possibilitou o diálogo entre teorias sistêmicas e aquelas que consideram a centralidade do ator social no processo de tomada de decisão.

Metodologia prática para estimação de parâmetros de geradores síncronos a partir de medidas de perturbações

Este artigo propõe uma nova metodologia prática e robusta para estimar parâmetros de geradores síncronos. A metodologia proposta utiliza a análise de sensibilidade de trajetória combinada com uma nova abordagem, denominada 'abordagem de minimização' para estimação de parâmetros de sistemas dinâmicos não-lineares modelados por conjuntos de equações algébricos diferenciais. Uma escolha adequada de entradas e saídas permite a divisão da estimação de parâmetros do gerador na estimação independente dos parâmetros elétricos e mecânicos. A metodologia é robusta com relação às condições iniciais dos parâmetros, não requer execução de testes especiais e utiliza apenas medidas de perturbações de fácil obtenção (correntes e tensões trifásicas, tensão de campo e velocidade do rotor) coletadas do sistema de energia elétrica sem desconectar o gerador da rede.
