SYSTEM AND METHOD FOR AUTOMATED AND INTELLIGENT QUANTITATIVE RISK ASSESSMENT OF INFRASTRUCTURE SYSTEMS

An automated and intelligent quantitative system and method for assessing risk in infrastructure systems including, but not limited to, gas, electric, water, sewer, transportation, and/or telecommunication systems. The invention incorporates a graph-based data structure of multiple infrastructure systems. The graph-based data structure includes a multi-layered structure with each layer having nodes for components of one of the multiple infrastructure systems, and edge links between related pairs of the nodes. A spatio-temporal and ontological reasoner performs spatial and temporal reasoning on the graph-based data structure to identify nodes of the graph-based data structure likely affected by the new activity event.
