Post-Hazard Learning, Risk Assessment and Decision-Making for Infrastructure Systems
Speaker: Armen Der Kiureghian, University of California, Berkeley
Series: CEE Departmental Seminars
Location: Bowen Hall Auditorium
Date/Time: Monday, April 14, 2014, 4:30 p.m. - 6:00 p.m.
Robust performance and rapid recovery of infrastructure systems in the immediate aftermath of a major hazard are crucial for mitigating losses and assuring well-being of communities. Infrastructures, such as transportation and communication networks and power, water and gas distribution systems, are especially vulnerable to natural and man-made hazards due to their spatially distributed exposure, interdependence between components, and multiplicity of failure modes. In this lecture, I will use the Bayesian network methodology to model the hazard and the infrastructure system and to process information gained from sensors, and I will use influence diagrams to make decisions on operational levels of system components and to prioritize component inspections. An application to a hypothetical model of the California high-speed rail system in the aftermath of an earthquake in the Bay Area will demonstrate the main ideas of the approach.
Armen Der Kiureghian is Taisei Chair Professor Civil Engineering at the University of California, Berkeley. His research focuses on probabilistic methods in civil engineering, including structural and system reliability, risk analysis and decision-making, and stochastic structural dynamics, all with special emphasis on addressing earthquake engineering problems. He is one of the founders of the American University of Armenia, an affiliate of the University of California, and has served as its founding dean of engineering and as interim provost concurrently with his Berkeley position. Among other awards, he is a recipient of the ASCE Alfred M. Freudenthal Medal (2006) and the George Winter Medal (2014). He is an elected member of the National Academy of Engineering.
