Risk‐averse optimization and resilient network flows
M Eshghali, PA Krokhmal - Networks, 2023 - Wiley Online Library
We propose an approach to constructing metrics of network resilience, where resilience is
understood as the network's amenability to restoring its optimal or near‐optimal operations …
