The project partner received two layout proposals for a new production line and wanted to compare them in terms of their suitability and performance. In the injection molding process, failure of individual injection molding cavities can occur, which leads to systematic or random missing parts. The system's modules can stop randomly, leading to additional waste. By means of the simulation, both configurations were examined quantitatively and the logistical key figures were compared. Possible bottlenecks, advantages and disadvantages were identified. The simulation model was designed to be as generic and modular as possible so that other systems of this type can be modeled later.
