Securing Critical Infrastructures via Geometric Modeling and Discrete Simulation

Next generation of awareness and security systems must integrate pre-existing subsystems with novel capabilities, including: virtual-reality and advanced interfaces, behavior and situation modeling, and data mining, on the common basis of 3D modeling and simulation. Through modeling and simulation of known behaviors, such a system may recognise the weak signals of risky situations, and promptly activate the countermeasures. Awareness requires knowledge: the infrastructure, the users, the resources, the events, must be dynamically modeled and simulated in their relevant aspects. The information on the infrastructure and its environment will be analyzed to determine the events dynamics as reported by networks of sensors (video-surveillance, movement, fire alarm, etc). Further knowledge is added by feed-back from the operators. Using both simulated and user-fed knowledge, an advanced system should also provide, in our vision, both training and decision-support tools. Such an advanced system is being developed to supply the security operators with optimized planning of normal operations and what-if simulation for emergency planning and crisis management. ∗p.assogna[at]theorematica[dot]it, bertocchi g[at]camera[dot]it, paoluzzi[at]dia[dot]uniroma3[dot]it, scorzell[at]dia[dot]uniroma3[dot]it, michele[dot]vicentino[at]libero[dot]it, roberto[dot]zollo[at]theorematica[dot]it
