A disaster assessment system is presented. The disaster assessment system generates one or more impact reports detailing the nature of how a disaster has impacted a building site based on sensor data associated with the building site that is collected after the disaster. According to one aspect of the inventive subject matter, the disaster assessment system includes a sensor platform, a pre-disaster database, a historic disaster database, and an impact assessment engine. The sensor platform obtains sensor data reflecting a building site before, during, and/or after an event. The impact assessment engine derives a pre-event 3D model based on sensor data collected by the sensor platform before the event, and derives a post-event 3D model based on sensor data collected by the sensor platform after the event. The impact assessment engine then generates the impact reports based on a difference between the pre-event 3D model and the post-event 3D model.

An impact assessment system and method for determining emerging criticality in a complex system is provided. The impact assessment system includes a component dependency model and an emergent criticality analyzer. The component dependency model describes the relationships between components in the system and their underlying dependency and criticality relationships. The impact assessment system receives component failure data from the complex system and uses the component dependency model and emergent criticality analyzer to determine the impact of the component failure on the criticality of remaining components in the system. The impact assessment system is thus able to determine how component failures in the complex system can impact the criticality of remaining components in the complex system and thus can assist in determining how those components may or may not be safely used in further operational activities.
