Background
For risk classification management and control, each industry has respective risk classification, identification and classification methods. And for dynamic risk management and control, implementing management and control responsibility according to the security risk assessment result and the corresponding management and control measures. The dynamic evaluation is embodied in the process of continuously executing risk identification and then managing and controlling along with the continuous change development of the production system, which has operability for project states with obvious nodes, however, the dynamic evaluation of the risk is realized by nodes with large projects, and the management and control of the risk are not good due to the large node range and period and the small and exquisite management and control of the risk. On the other hand, in the field of water conservancy and hydropower engineering, a more mature evaluation model is calculated for dynamic evaluation from four dimensions by using dynamic adjustment coefficients, and the evaluation is comprehensive and sufficiently refined, however, the dynamic evaluation is difficult to realize due to lack of a standard triggering comprehensive dynamic evaluation, and risk management and control is not active. And because the evaluation is comprehensive, the workload is relatively large, if all risks are comprehensively evaluated, unnecessary waste is caused, the effort is low, and the risk management and control is also a disadvantage. In the process of implementing risk dynamic management and control, the risk dynamic assessment is triggered by combining the management and control states, so that the dynamic assessment is established on the same standard, the risk dynamic assessment is more floor and has operability, and the risk management and control for safety production is more beneficial.
