There are two reasons why a model may .not be considered acceptable by the users. Firstly, the mathematical description may have been made in the absence of adequate information. Secondly, it might not be possible to formalize all of the essential features of the object by mathematical meańs, or these features may not be known at all. Toerefore we may call a mathematical model containing a formal description ( with an acceptable level of accuracy) o/ not all the essential features of the . object under consideration an incomplete mathematical model.}, title={Strategic Regional Policy: Paradigms, methods, issues and case studies.
