Proposta de arranjo físico baseado nos conceitos da produção enxuta para uma fábrica de estruturas metálicas

Abstract

In a factory of steel structures, the movement of parts is a factor that must be considered, because its components have big size and high weight. Thus, unnecessary transport due to bad positioning of the equipments causes losses like increasing production time, low productivity, among others. The objective of this study is to develop a layout to a new plant of steel structures. The company had a quick growth in recent years and need more space. However, the new plant was installed without an appropriate study of facility layouts. The proposal has been built according to the methodology of building layouts called SLP (Systematic Layout Planning). The data required for the application of the system were collected through a case study. To evaluate the alternatives and choose the ideal layout were used the concepts of lean production, because the system is aimed at loss reduction and is often used in factories looking for a market differential. Were generated three proposed layouts and compared with the current layout. Based on the results, the selected layout was the proposal C, which besides decreasing about 40% of current transport, eliminated four of the seven wastes that should be avoid in the lean production.
