[Simulation as a method for solving medical technical problems]

The present paper first presents a comprehensive overview of the methodological aspects of simulation. It lists the various approaches to the modelling of real-world systems and emphasizes the respective constraints on the interpretation of model data. For this purpose, a classification of typical applications of simulation models is given, and is followed by a discussion of three structurally different ways of constructing a model. The correct matching of these modelling concepts to the particular application problem in hand is discussed, with special consideration being given to the drawing of conclusions from, and the interpretation of, the simulation results. To round of the classification, the simulation models are differentiated in accordance with the nature of their implementation. By defining application type, modelling concept and model implementation, an understanding of the validity and appropriate application of any industrial model is derived.
