Registration Date 09-03-2020 Organization Ukrainian State University of Chemical Technology popup.description2  The object of study is the process of creating an effective method of mathematical modeling of complex technical systems under uncertainty. The purpose of the work - algorithms and methods for solving the problem of modeling complex technical systems. Research Methods - Theory of partial differential equations, Theory of multidimensional Pade-type approximations, Probability theory, Elasticity theory, Mining mechanics, Mechanics of deformed solids. Investigated: the model of operational reliability of oil tanks; model of stress-strain state in the rock mass under dynamic loading through the well; mathematical model of winding carbon fiber into square mandrel. A modified parameter extension method for estimating frequencies and modes of linear and nonlinear oscillations of plates with complex boundary conditions is proposed. The results obtained can be used to determine the technical condition and reliability of engineering and building structures, as well as to make informed decisions about the feasibility or feasibility of their operation. Field of application: M 72.19 Research and experimental development on other natural sciences and engineering. Product Description popup.authors Borzov Serhii O. Nasonova Svitlana S.
