Methods, tools and techniques are divided into: general applications of selected methods (eg, Analytical Hierarchy Process (AHP) analysis using cross-interaction analysis using event tree (ETA - Event Tree Analysis) Analysis of the causes and consequences, Benchmarking, and Sensitivity Analysis susceptibility testing, cause and Effect Diagrams, Fuller's method, risk matrix, Delphi method, the theory of extremes, etc., specially adapted general methods for analyzing and assessing risk. Emphasis is placed on the basic working methods of risk engineering and examples of their use.
