Van Hentenryck’s research in resilience focuses on evacuation planning and scheduling, flood mitigation, and the resilience and risk mitigation of complex multi-sector infrastructures. Research in evacuations has led to the design and implementation of novel planning and scheduling algorithms that scale to large cities and disasters. These algorithms reason about time and congestion, as well as various aspects of human behavior and constraints typically required in practical settings. These evacuation planning tools were motivated by many practical settings and collaborations with emergency services in Australia. Van Hentenryck also works on mitigation strategies and infrastructure improvements for floods. See these slides for a summary. Research in complex infrastructures has focused primarily on addressing the interdependencies between electricity and gas networks.
