Perspectives on Modeling Interdependent Infrastructure Network Resilience
Kash Barker - University of Oklahoma
April 9, Friday, 16:00 (GMT+3)
The seminar will be via Zoom.
Meeting ID: 993 766 4491
The importance of infrastructure networks to economic productivity, community health, and societal way of life requires a thorough set of models describing various aspects of their (i) vulnerability and (ii) recoverability. This talk provides several perspectives on modeling these two dimensions of resilience. The first research perspective includes a new tri-level optimization model for a protection-interdiction-restoration problem in interdependent networks along with hybrid solution algorithms. The second perspective offers a means to account for socio-economic factors in pre- and post-disruption investments with a social vulnerability measure. The third perspective addresses the real problem of routing restoration work crews on a transportation network to recover disrupted components in another infrastructure network. The fourth accounts for the wider spread economic impacts of infrastructure network disruptions, giving a means to measure the multi-industry effects of investing in vulnerability and recoverability strategies. Other topics in restoration facility location and component importance measures will be discussed, as well as on-going and future research work.
