If you are interested in the coupling with the value stream simulator or in a central project management to exchange your value streams with colleagues, please contact simvsm@simplan.de with the keyword "SimVSM Pro". - By connecting to a value stream simulator, you also get a dynamic evaluation of the modelled value stream. This includes the development of on-time delivery, process utilization, bottleneck analysis, throughput, stock levels and lead times against the background of dynamic conditions over time. - Project management allows projects to be stored centrally and exchanged with authorized users.
