Value stream mapping and lean simulation: a case study in automotive company
This work aims at applying the concepts of value stream mapping (VSM) in an auto parts company in the ABC region of Sao Paulo. By mapping the current state of art, it was possible to identify the waste present in an assembly line of clutch discs. The future state was suggested with improvements for elimination of waste and reduction of lead time, which went from 60.5 to 4.14 days. Simulations were made using current and future states to support the suggested improvements, and reduction of 7 in total production time was verified, as well as 10 increase in the use of work positions. The results showed that VSM combined with simulation is a good alternative in the decision making for change in production process.
