Lean and simulation
The VSM (Value Stream Mapping) is established when implementing Lean. It is a static mapping of flows.
The simulation is a dynamic analysis which takes into account the variability, the uncertainty and the random aspect of flows and process.
Simulation is thus a complementary approach to Lean:
- It adds the fourth dimension, the time, to Lean;
- It helps the analysis and the evaluation of the current and future situation of your VSM;
- It measures the impacts of changes and scenarios before the setting-up of the future VSM.
