ion Validation Implemen tation Verification Validation Computation Specific Model Validation Transformation <-Figure 3: Summary of the various conceptual stages in the development of a computer experiment Where the computation specific model consists of representing the derived conceptual model into a language that can be implemented. One of the things that often goes wrong in these stages is that the scientist tends to confuse his code with a conceptual model or-even worse- with the natural system itself, the researcher has falling in love with his model! This is a situation we should be prepared for and try to avoid at all cost. One way to maintain a critical attitude is to carefully design and test sub stages in the modelling and simulation cycle and to add primitives to the simulation that constantly monitor for 'unrealistic' results 6 I.2 A closer look at system models In the next paragraphs we will use some concepts from the fields of (discrete event) computer simulations, the ...
