Abstract: Serious gaming for interrelated critical infrastructure (CI) resilience improvement includes receiving from a serious gaming participant a selection of an anomalous event for a geographic region for which a hierarchy of CI elements has been modeled, and a specified change in allocation of at least one resource in a corresponding one of the CI elements. A previously determined cascading impact upon the CI elements resulting from the anomalous event is then retrieved and compared to a hypothetical cascading impact produced by a simulation of the model with the specified change. A visualization of the comparison is transmitted to the serious gaming participant so as to show the result of the hypothetical change in resources upon the cascading impact of the event in the hierarchy of CI elements.
