Resource & Exchange Dynamics

Anticipating vulnerabilities on networks carrying the flow of information, energy, and materials

Infrastructures are networks of dynamically interacting systems designed for the flow of information, energy, and materials. Under certain circumstances, disturbances from a targeted attack or natural disasters can cause cascading failures within and between infrastructures that result in significant service losses and long recovery times.

Modeling capabilities are needed to evaluate the robustness of various systems and to identify factors that control the scale and duration of disruption. The capability described here lays the foundation for developing advanced system security solutions that encompass both external shocks and internal dynamics.
