ABSTRACT
The term “modelling” is commonly interpreted as replacing a real object under consideration by another object – a model. One of the reasons of doing so is the ability to draw information about the object from examining the model. The model imitates (mimics) selected aspects of the (possibly very complex) real object of interest, which are deemed important in the study at hand, while for economy of computation and for clarity, the model should omit those aspects which are deemed unessential in the specific study.
