Disclosing Uncertainties in System Analysis Problems

Abstract

Disclosure of uncertainties is an important problem for the class of system analysis formalizable problems. First, we will notice that uncertainty is a typical property of system analysis practical problems. It is connected with the diversity of goals, properties, and system analysis object features. Applied problems without uncertainties are rather the exception than the rule. An adequate problem statement usually has various types of uncertainties, which reflect the natural state of a researcher. His knowledge is always rather incomplete and inaccurate. It directly follows from the GЦdel theorem about incompleteness [103] and the evolution of human cognition. If everything were known with certainty, completely, and exactly about the processes, factors, and evolution of the Universe, then civilization would stop developing.
