摘要：In today's technologically advanced society the dependency of every citizen and company on working infrastructures is extremelyhigh. Failures of critical infrastructures, such as the Italian blackout in 2003 or the failure of power supply in wide parts of Europe in2006, demonstrate the strong linkage of networks across borders. However, also infrastructures within the same geographic regionbut of different types have strong interdependencies and failures in one type of network can have cascading effects onto the othernetworks. In order to support risk analysis and planning of emergency response actions the modeling of critical infrastructures andtheir mutual dependencies in 3D space is required. Decision makers need a comprehensive view of the disaster situation to be able toestimate the consequences of their action. For this purpose, a comprehensive understanding and simulation of cascading or loopingeffects as well as the propagation of the disaster extend is needed. But neither the existing utility networks models nor theinternational standards for modeling cities or buildings map the mutual interrelationships between different infrastructures orbetween the city and its infrastructures.In this paper the requirements and a novel framework for the integrated 3D modeling of critical infrastructures within cities ispresented. By giving a dual representation utility network components are modeled both according to their 3D topography and by acomplementary graph structure embedded into 3D space.
