Value stream mapping (VSM) is a widely adopted method for transformation of production environments into a lean operational state. However, attributes of the ‘paper and pencil’ approach result in limitations when applying VSM in complex production environments. Using ExtendSim, an enhanced VSM method is developed featuring a feasibility and trade-off analysis which is incorporated into the VSM procedure. A case study covering a process of exhaust gas purification catalyst production is then conducted to test the newly developed method. The VSM project yields a shop floor lead time reduction from 11.4 to 1.4 d.
