Karazin Kharkiv National University popup.description2  The object of research is complex systems, which in the process of functioning and development require an image of the current state for identifying the peculiarities of the system's development. Subject of research - methods of modeling complex systems; models, methods, methods of informative features based on informational, geometric, spectral analysis of integral characteristics of the functioning and development of complex systems; models that determine the behavior of systems based on their internal structure. The purpose of the work is the research and construction of mathematical models, the development of effective methods of image of the current state of a complex system. The research method is dynamics modeling, structure, behavior of complex systems, estimation of model adequacy. Stochastic dynamic models of wave processes have been developed, in particular, a dynamic model of the sea surface has been constructed, which takes into account the distribution of heights, inclination of waves, and points of flickering. Distribution of mirror points, emission distributions for circular random curves, distributions of overloads of moving objects were found. Matrix metrics built for clustering macroeconomic systems of sub-Saharan Africa. Algorithms with different metrics are used to analyze the economic situation in this region.
