Network Resilience is Key to Surviving Compound Hazard Events, Scientists Say

As weather extremes such as Superstorm Sandy, which swamped New York City’s subway system in 2012, increase in frequency and intensity and as cybercriminals ramp up attacks on technologies that tie together urban infrastructure systems, networks critical to the flow of data, people, goods, and services must be made more resilient to failure, according to a team of scientists.

“To be able to quantify and compute system failure profiles is critical information that planners might need to make decisions in terms of how to recover these systems,” said Samrat Chatterjee, a data and operations research scientist at Pacific Northwest National Laboratory (PNNL) in Richland, Washington.

“If we are unable to characterize how the system is failing or might fail, how can we intervene and recover in an efficient manner?” he added.

Chatterjee is serving as principal investigator on a project with colleagues at Northeastern University in Boston, Massachusetts, that is developing computational frameworks to improve network resilience.
