| The type of ERA | Main Methods |
| Health risk assessment | Dose-response and exposure model (e.g. passion model, logistic model, time series, multi-regression model and so on), expert judgment, Monte Carlo Simulation, and Bayesian model |
| Accident risk assessment | Retrospective and status-quo assessment, scenario analysis, expert judgment, fault-event tree, probability statistic model, fuzzy mathematic model, and risk matrix model |
| Natural disaster risk assessment | Retrospective and status-quo assessment, disaster loss-exceeding probability curve”, “entropy weigh” method, expert judgment, comprehensive risk index method, and risk matrix model |
| Regional comprehensive risk assessment | Except for methods for above three types of ERA, comprehensive risk index method, fuzzy comprehensive assessment method, expert judgment and regional risk zoning model were also commonly used |
| ERA for decision-making processes | BCA, Decision-tree analysis, MCDA including MAUT, AHP, and Outranking |
