Reliability and topology based design of infrastructure interfaces

Funding: National Science Foundation
Students: Xing Min, Min Ouyang Ph.D.

This project focuses on the reliability-based design of infrastructure systems considering both network topological features and network interdependence. Positive and negative effects of interconnectedness are studied for a broader exploration of infrastructure coupling. Modern inverse reliability tools are adopted in this research to design multi-network systems that achieve targeted network-level performance.  Such target designs consider the reliability of individual components, connecting links, and inter- and intra- network topological features. The balance between coupling strength (IS) and density (ID) under conflicting objectives of operational efficiency increase and failure propagation decrease is optimally achieved in the design.
