Research on Scenario Construction Method and Emergency Response Capacity Evaluation of Critical Infrastructure Incidents

Critical infrastructure is the basis for normal operation and healthy development of the city. With the correlation and dependence between critical infrastructures increasingly strengthened, critical infrastructure disasters often bring huge economic losses and serious social impact, and improving emergency response capacity of critical infrastructure has become an important prerequisite for protecting normal operation of the city. With the critical infrastructure as the object of research, based on the correlation feature of critical infrastructure, this paper analyzes the characteristics of scenario construction of critical infrastructure from malleability, influence objects and duration, and presents the method of scenario construction of critical infrastructure, then puts forward an idea of emergency capacity evaluation from three dimensions of accuracy, sufficiency and timeliness. At last, this paper applies the common method to gas multi-gate station incident scenario, which verifies the feasibility of this method.
