Estudo e levantamento estatístico do mapeamento do fluxo de valor (MFV), através da análise de seus efeitos na transformação de uma manufatura enxuta

Abstract

Gaining competitive advantage and differentiation in the market place is essential for any company that wants to thrive. In the presented context, the usage of a flexible manufacturing system might become a source of competitive advantage, however, the implementation of the Toyota production system is still an obstacle to be surpassed due to the lack of knowledge of the available tools. Therefore, this paper presents a study about the Value Stream Mapping Tool, which was recently developed and is still under used. It is among the set of many tecniques and concepts of the lean manufacturing. Besides the theoretical study throught the reading of many renowned references about the theme, data was collected from 33 case studies and made possible the prediction of 52 to 66% of lead time reduction with a confiability of 90%. Considering the critical analysis of the articles that had the largest reduction in lead time, it was noticed that they were associated with the application of many others lean manufacturing tools, specially the 7 waste mapping tools. Thus, value stream mapping helps a structured and stretegical application of various Toyota Production System’s techniques aiming to reduce inventories and lead time. Regarding the cycle time, no strong relationship between the application of the value stream mapping and the reduction of cycle time was noticed.
