RESILIENCE AND INTERDEPENDENCIES OF CIVIL
INFRASTRUCTURES DURING EMERGENCIES

The fundamental concepts of “community
resilience” are analyzed and a common reference framework is established. Several applications of the framework are
presented for strategic facilities (e.g. hospitals and schools) and
infrastructure networks (e.g. gas, water, power etc.) that are the basis of
life and economy of every community.
The hospital and the school are assumed located
in California and retrofitted with two different strategies. First, the
traditional performance-based earthquake evaluation tools are used to estimate
the repair costs and the downtimes which are used as input of the proposed
methodology to evaluate the resilience index.
However, during an emergency, the Hospital Emergency Department not only
should be safe and damage resistant, but it should also be functional.
Therefore, an organizational model of the ED is presented using a discrete
event simulation model while taking into account also the emergency plan. An application of the organizational model to
the hospital network of San Francisco hospitals is presented.
At the regional level, a method to take into
account interdependencies for the evaluation of resilience is also presented
and applied to the prefectures which were affected by March 11th 2011 Tohoku
Earthquake in Japan. A logical
methodology to take in account the cascading effects during an emergency and
the propagation of the probability of failure within a network is also
presented.
Finally, the use of new information technologies
to improve resilience and disaster management is also investigated showing a
new multiplatform application for smartphones which can be used for field
reconnaissance. The proposed app can
also be used in a simplified version by normal citizens to give an initial and
quick damage evaluation of the area, which is going to be very useful when
resources (e.g. the number of specialists is limited). The application has been
tested for the first time during 2012 Emilia earthquake in order to enhance the
emergency response, showing the efficiency of the proposed method.
