Is there a unified risk assessment method?

Han O3 10 10 recommends 3 1 specific risk assessment techniques and methods, among which only the risk matrix is unique in the field of risk management, and the rest are not unique in the field of risk assessment. For example, FEMA, event tree analysis and Monte Carlo simulation are all applicable to risk assessment.

In ISO3 10 10, the application scope of different methods is also analyzed in detail, and each method is explained according to the degree of uncertainty, the difficulty of risk assessment methods, the availability of resources, whether quantitative results can be output, and which methods are suitable for which stage, which are very useful.
