This paper presents a simulation-based planning software, that is developed for high complexity production settings and currently undergoes first real-date Industry application tests. The software is tested in commercial vehicle assembly, but will be also employable in other industries with a sufficiently high number of different products and variants. The solution enables the forecasting of required personnel and the requirements with regard to temporary additional workers ("floaters") for every cycle at the production line. To this end, the software periodically collects process times, sequence and feature data for the vehicles. The cumulated workloadis calculated under consideration of flexibilities. A web-based user interface enables to set and change reference data, define process simulation and allows for the compilation of diagram and charts for the analysis of the results of the different simulation runs. Various filters as to time periods, vehicle types or feature variants allow the plannere a target-oriented analysis and provide feedback for improving the tact of the production line. Finally, some qualitative results of a first industry test in commercial vehicle assembly are presented.Those preliminary resulsts give valuable feedback about the usability of existing analytical features and desirable additional features.
