Justifying Calculations of the Security of Promising Machines and Man–Machine Systems on the Risk Criteria of Accidents and Disasters

Further development of calculation and experimental analysis methods and ensuring their security against risk criteria for the prevention of accidents and disasters is considered. Of particular importance in this direction are the methods and technologies of both computational and physical modeling and analysis of the limiting states of structures leading to catastrophic failure. It is shown that the most promising direction of creating an effective apparatus for risk assessment and analysis of the security of technical systems can be considered the use of hybrid methods that allow taking into account both stochastic and interval uncertainties of the risk parameters in determining the safety and security conditions of man, the technosphere, and nature from manmade accidents and disasters.
