The theoretical generalization is provided for methods of control systems synthesis of impulse processes of complex systems CM with unirate and multirate coordinates sampling. Stabilization and coordination problems for impulse processes are considered. Digital simulation of IT-company development scenarios was done based on control of impulse process in the proposed CM.

New statements, methods and algorithms for solving problems of investment control, arising in the study of control strategies of stock portfolio, have been considered. The tasks of mathematical modeling and analysis of qualitative characteristics of processes, describing the dynamics of the formation of a stock market value and shares portfolio, are formulated. The peculiarities of application of the analysis of the trajectories in solving the problem of diversification of the risky stock portfolio are investigated.

Cortege operators concept is implemented for version when cortege is a set of matrices with fixed dimensions. The suggested concept allows one to transfer constructive tools of describing the basic linear and nonlinear structures of numerical vectors Euclidean space to matrix Euclidean spaces with preservation of the basic relations and ties. This completely concerns the use of these structures in applied problems of classification and clustering. The critical moment is that the difficulty of describing such structures in the matrix Euclidean spaces is not greater than the difficulty of describing the numerical vectors for Euclidean spaces and is reduced to the eigenvalue problem for matrices.

There was solved the problem of constructing three-dimensional field of transverse dynamic displacements of a thick elastic layer loaded surface with normal and tangent dynamic efforts under discretely and continuously determined observations of its initial state. The number of such observations as well as the regions in which they are given are not regulated. The uniqueness conditions of the obtained solution and its mean square consistency with observations of a layer are determined.

The research of complex approach to the selection of the optimal hypothesis in classification problems based on the class of hypotheses distributed with respect to the posterior probability is presented. The approach is based on determining the relative weighted average value for data distribution and the use of depth functions operating in the space of classification functions. Depth-dependent threshold properties of the weighted average value are studied as well as the procedure for using convex evaluative functions for the formation of posterior probabilities is improved.
