Aplicação de conceitos lean no desenvolvimento de uma planta industrial

Abstract

The Brazilian industry has been going through a deep market crisis caused by the economic recession started since 2014. Being specific, the shipbuilding industry has been affected by the lack of new projects and investments which has led to the closing down of some shipyards. So, the shipyards are working hard to survive. For that, it's required a continuous application of new concepts, tools and skills aiming at having leaner and more flexible processes. On the other hand, wind energy represents the fastest growing of alternative energy source in the country in recent years. Thus, this study presents the application of lean concepts in the development of an industrial plant to manufacture an innovative wind tower model in a shipyard. The case study proposed in this article aims to: verify the constructability of manufacturing of the wind towers in the shipyard; apply Lean Manufacturing concepts/tools such as Just in Time and value stream mapping (VSM), and finally, develop a virtual layout (2D+3D) of a wind tower plant by applying fundamentals to waste elimination. Considering that it is an innovative development, for the product and for the process, the results of this article are qualitative because of the lack of comparative references. Finally, the layout of the lean industrial plant was designed focused on the high productivity based on Just-in-Time concept. That is, using the minimum amount of resources to produce the right quantity of products, in a short time when required by the client.
