Abstract:

Critical infrastructure is the basis for normal operation and healthy development of a city. Given the increased correlation and dependence between critical infrastructures, a disaster that happens to critical infrastructure often brings 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 city. With the critical infrastructure as the object of research, based on the correlation feature of critical infrastructure, this paper analyzes the characteristic 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 scene, which verifies the feasibility of this method.

Key words: critical infrastructure, scenario construction, emergency capacity, correlation
