The purpose of the work is to develop models of complex technical systems that have deviations of technological origin or work in conditions of uncertainty, as well as processing and storing data related to them. Research methods are the theory of differential equations in partial derivatives, the theory of multidimensional Padé-type approximations, the probability theory, the elasticity theory, mining mechanics, mechanics of deformed solids. The following were investigated: the parameter continuation model for estimating the frequencies and modes of linear and nonlinear oscillations of plates with complex boundary conditions; image storage model using Padé-type approximations. The obtained results can be used to determine the technical condition and reliability of machine-building and construction structures, as well as to make informed decisions about the possibility or expediency of their operation. Field of application: M 72.19 Research and experimental developments in the field of other natural and technical sciences. Product Description popup.authors Borzov Serhii O. Velychko Tetiana V.
