Traditionally Value Stream Mapping (VSM) is used for quick analyses of product flows through a manufacturing system, from raw material to delivery. Discrete Event Simulation (DES) is often used for analyses of complex manufacturing systems with several products and a complex planning. These two methods have similarities but also differences. This paper presents a concept for creating dynamic value stream maps of a system using simulation. Creating dynamic value stream maps makes it possible to analyze more complex systems than traditional VSMs are able to and still visualize the results in a language the Lean coordinators recognize. The value stream map is presented in an spread sheet that can be altered in the way the team wants. Some standard icons are predefined, based on traditional VSM icons. One or more products can be visualized at the same time and simulation runs and results compared immediately, helping choosing the best solution.
