Lean production. Value stream mapping. Monte Carlo simulation.Abstract
Lean Production (LP) emerges as a response to the increase in competitiveness in a globalized market. Among the practices utilized in LP, value stream mapping (VSM) is one of the most adopted, as it identifies wastes and direct the application of other LP practices. VSM maps material flows and production control information. However, VSM has a deterministic approach, which limits the power of modeling and makes it difficult to map dynamic models. In this sense, this work has the goal of proposing a method for the identification of opportunities for improvements that combine VSM and Monte Carlo simulation, taking into account the uncertainties of the value flow. The results show that this new approach allows the identification of improvement opportunities that are not contemplated in a traditional application of the VSM.
