2 The modelling and simulation process 6 Figure 7: Measurement data A number of Information Sources (either explicit in the form of data/model/knowledge bases or implicit in the user’s mind) are used during the process: 1. A Priori Knowledge: in deductive modelling, one starts from general principles Œsuch as mass, energy, momentum conservation laws and constraintsŒ …
