Классификация неопределенностей в задачах моделирования и управления сложными слабоформализуемыми системами

The article describes the development of classification principles referring the uncertainty types inherent in the complex and hardly formalizable systems during the two lifecycle stages including the design and functioning. The graphic structure of the developed classification division of uncertainty types is given. The place of each type of uncertainty in the analysis procedure, simulation and control of the selected class of complex systems is shown.
