Kurzfassung:
Crowd simulations are an indispensable tool to review evacuation concepts. Since uncertainties limit their reliability, I propose and implement a three-step approach to reduce epistemic uncertainties: I identify influential parameters, calibrate them, and quantify the output uncertainty for a safety-relevant scenario. The result is a specific model that provides predictions with considerably less uncertainty. In this way, this work contributes to increasing the reliability of crowd simulations.
