A Model is a theoretical description of a eonsidered objeet (or a process).
The properties and characteristics of the model should be conyergent to the objeet properties and characteristics according to some criterion.
The description should be simplified so that one could analyse the model with use of available methods.
However the simplification level should enable to obtain some new knowledge about the modelled objeet basing on investigation of its model behaviour.
