Procedia Structural Integrity 22 (2019) 51–58 First International Symposium on Risk and Safety of Complex Structures and Components Application of risk-analysis methods in the maintenance of industrial equipment S.V. Belodedenko * , G.M. Bilichenko, О.M. Hrechanyi, M.S. Ibragimov Departament “Machines and units of metallurgical production”, National metallurgical academy of Ukraine, Dnipro, 49600, Ukraine Abstract In the aspect of an individual approach to reliability and risk assessment, the resource safety index method is considered. Its use for large structures and complex systems gives a less conservative estimate of the guaranteed lifetime. The amalgamation rules of individual indicators of reliability and safety of separate elements of the system are offered. The efficiency of the methods is demonstrated on the example of the evaluation of the blast furnace casing technical condition.
