Abstract: To prevent particularly serious accidents and major accidents in urban areas and have a proper assessment of the operation of the urban safety risks management and control system, this article first selects major factors affecting the urban safety management to set indicators of such a system by using the AHP and the grey correlation method. Following that, a risk control judgment matrix is established to define the weights of different indicators and have a dynamic evaluation of the system based on actual cases. Finally, the article takes the operation of the safety risks management and control system for preventing particularly serious accidents and major accidents in a coastal city as an example to illustrate the effectiveness of the above indicators. The result shows that the indicators set in this article can help to find out the overall performance of the urban safety risks management and control system, pin down the vulnerable points and define the key factors in future safety management.

Key words: analytical hierarchy process(AHP), grey correlation method, urban safety risks, particularly serious accidents and major accidents, management and control system, assessment
