Dr. Dueñas-Osorio’s team is developing methods to measure and predict how critical infrastructure systems affect each other during normal operation and when exposed to extreme events. Interactions between power, telecommunication, water and gas networks provide the initial focus of the investigation. Preliminary findings show that cascading failures across distinct systems are preventable via infrastructure interface topology and operational control, as well as by strategically locating back-up and redundant system components. Overall results from this project are expected to improve modeling techniques and inform utility design guidelines from the American Society of Civil Engineers (ASCE) regarding optimal coupling density and coupling strength across systems to reduce failure propagation and outage times.
