The purpose is to obtain new theoretical results in the field of nonlinear analysis, evolutionary modeling, the theory of symmetry, the research and development of new and effective methods of analysis, forecasting, solving discrete optimization problems. Research methods belong to discrete nonlinear dynamics, fuzzy mathematics, the possibilities theory, the decision theory, discrete optimization. Construction of decision-making new fuzzy methods based on evolutionary models and models that based on fragmentary structures, applying new approaches to the formalization of complex systems and the search for optimal solutions. The problem of accuracy and efficiency of EMF-algorithm for problems having a fragmented structure is solved. To improve the accuracy of behavior systems predicting, which tend to lag developed hybrid forecasting methods based on the use of nonlinear dynamics discrete tools, in particular, the model of a homogeneous structure, ARIMA-models, genetic algorithms, and adaptation module influence of fundamental factors. It is further developed the method of comparative analysis of the fuzzy nonlinear dynamics. Scientific innovation is the development and application of new approaches to forecasting the dynamics and structure analysis of complex systems, the construction of new mathematical models, the development of efficient algorithms to solve them. The scientific significance of the results is their focus on the mathematical modeling development and computational methods as tools, construction and study of complex socio-economic and technical systems. The developed models and tested methods for the solution of applied problems arising in the real economy, and can be used in the development and implementation of computer systems to support decision-making in economics, engineering, management, marketing, logistics, etc. The results of research put into practice enterprise PC "Zaporizhzhya Media", LLC PTF "Avias", the Main Department of Finance Zaporizhzhya regional state administration, public institutions Pology region Zaporozhye region, as well as in the learning process in teaching ZNU three professionally oriented subjects ("Optimization models and methods", "Modeling of Economic Dynamics", "Optimization Methods") and four special courses ("Methods of financial decision-making", "Evolutionary Models", "Models of Financial Markets", "Time Series Analysis").
