Time-dependent resilience assessment and improvement of urban infrastructure systems.
This paper introduces an approach to assess and improve the time-dependent resilience of urban infrastructure systems, where resilience is defined as the systems' ability to resist various possible hazards, absorb the initial damage from hazards, recover to normal operation one or multiple times during a time period T.
