Monte Carlo simulation with modelica

Monte Carlo simulation allows to obtain statistical information derived from estimates of the random variability of component parameters. The paper demonstrates how to describe the random characteristic of parameters in a tool-independent manner in Modelica. Using the multi-run facilities of a simulation engine statistical analysis can be carried out without any code intervention concerning the tool. The approach is based on the SAE 2748 standard. Solutions of implementation problems with respect to Modelica are discussed. This paper is based on results, which were developed in the Fraunhofer collaborative project "Computer Aided Robust Design (CAROD)".
