O mapeamento do fluxo de valor como mecanismo de aperfeiçoamento no processo produtivo em uma fábrica de eletrodos revestidos

Abstract

Business is increasingly challenging and dynamic, forcing managers to adopt strategies to create a competitive differentiation in order to market demands. This reality makes companies use tools that assist in routine management and production flow optimization. In view of this, the main objective of this study is to propose improvements in the electrode manufacturing process in a factory located at state of São Paulo, including three models (E6010, E6013 and E7018). The basis for the development of the work was the value stream mapping and lean production tools, through the VSM, it is possible to visualize the holistic way of the process identifying the steps that really add value and TPS tools that support the building of improvements and the preparation of a future map. As a solution to the problems it is proposed to use the methodologies: Kanban, quick tool change, layout change, 5S, quality control, capex, job safety, FIFO storage system, jidoka, Poka-Yoke and total productive maintenance. It is an applied research of quantitative and qualitative nature. It uses observation techniques, semistructured interviews, bibliographic and documentary research. In order to understand the operation, visits were made to interpret the steps of value creation and the variables that most influenced the process. Through this it was possible to know the process, assemble the VSM and suggest lean tools that help the production system.
