Simulation modeling is a valuable complement to, rather than a replacement for, the traditional lean manufacturing analysis tools.
For example, value stream mapping is a key tool; it is a good beginning. But it is static and typically only done for high-volume products or classes of products. Simulation allows the value stream map to become dynamic, and to model the range of probable val- ues—not just averages. It also allows linkages to other tools such as projected capacity utilization in a consistent manner.
