Ways of identification of complex systems

To identify complex systems, models of different types are used depending on the goals set. The complexity of the choice of models is due to the complexity of the behavior of the systems under consideration at various times during which the basic properties of the systems can drastically change. Main part. The example of the airborne carousel E. Lorenz shows the use of fractal modelling to describe the behavior of numerically irreducible systems.It is presented an algorithm for determining the area of self-similarity of the object under consideration. According to the authors, the algorithm allows ones to reduce the probability of the object malfunctioning. Conclusions. It is considered a possibility of applying the fractal models for identification of complex systems.
