BARTH BARTZ, Ana Paula; WEISE, Andreas Dittmar  e  RUPPENTHAL, Janis Elisa. Application of lean manufacturing in an industry of agricultural equipments. Ingeniare. Rev. chil. ing. [online]. 2013, vol.21, n.1, pp.147-158. ISSN 0718-3305.

With increasing competition and the need for improved competitiveness, companies who adopt the lean production system have some advantages, because they deal better with the information, increasing their efficiency. The objective of this study was to decrease the lead-time required by the studied company, by practical application of just-in-time searching for lean production in a metalworking company, manufacturer of agricultural implements. To meet this purpose, a case study of qualitative and descriptive order was carried out. To collect data, observation and documental analysis were performed, in order to understand the production processes, then working with the collection of data, through structured interviews in order to identify the difficulties encountered by suppliers in providing the supplies within the agreed specifications. The company had high indexes of late delivery of their products because of the high lead-time. Through the development of the mapping of actual flow, it was found that the organization was working with a production pushed and much of the late occurred because of problems in the supply of inputs. By eliminating tasks that did not add value to the final product, a lean value flow was produced for the process, identifying the major problems which caused the suppliers to provide the supplies out of specification or out of date and suggested actions that could be implemented for the elimination of these delays. Through these actions, the reduction in lead time was observed, helping to better meet delivery deadlines, increased competitiveness, a relevant fact to keep in today's market of agricultural equipment.
