In particular, a mathematical model of the deformation of layered orthotropic shells has been developed for discrete consideration of the components in the presence of damage on the interfaces; the improved scheme of the finite element method was verified, based on which the methodology for determining the bearing capacity and residual strength of the specified shells was developed in order to assess the possibility of their exploitation, and recommendations for its use were developed; structural and flow models of complex network systems were built; the main structural and functional characteristics of the components of such systems are determined; to study the behavior of hierarchical network systems and processes of intersystem interactions, a model of comprehensive assessment of their state and functioning efficiency was developed; effective parallel algorithms for interactive evaluation of network systems and preliminary processing of large arrays of input data are proposed; a parametric optimization method was developed in relation to the problems of optimal control of nonlinear manipulation systems with complex restrictions on generalized coordinates and control; within the flat system of solid bodies, a mathematical model of the gait of a person with a load on his back was constructed. The obtained scientific results can be used for real-time research of complex hierarchical network systems of various types and improvement of design parameters of manipulation systems and orthopedic devices for loaded gait. Research results are used in the educational process of training specialists in programming, information systems and technologies, system analysis and artificial intelligence. Appropriate methodologies and algorithms are implemented in calculation and design practice at the Yuzhnoye State Design Office. Product Description popup.authors Butyter Ihor B. Goriachko Taras V.
