This paper shortly examines the processes of production and justification of hypotheses in formal and non-formal systems. Different points of view on inductive approach are shown. The levels of hypotheses in complex systems are brought in practice. The properties of inductive inference are defined and studied. Interaction between induction, traduction, abduction and deduction in generation and justification of hypotheses are analyzed. It is shown that for modeling these processes it is necessary to develop the formal methodology, which provides the integration of all classes of inference models.
