1 Introduction
-
a simulation can typically be understood even by non-professionals increasing the acceptance rate
-
a simulation is modular and can be easily expanded or adapted if more complex or different questions arise
-
a simulation can reveal underlying distributions and, thus, can reveal the uncertainty of results
2 State of the art
-
goal and task description
-
system analysis and model formalisation
-
implementation and experiments
