Resilience metrics for lifelines
Service performance over time during and after disruption is described by robustness, rapidity of recovery and lost service, so that interventions can be compared on the same curve.
GCRI · Binesaziya girîng
Reliability and resilience engineering is the method this platform stewards for the network. It designs infrastructure to withstand, absorb and recover from failure through redundancy, diversity, protection and planned restoration, and it measures how well pergalan perform when stressed.
Reliability and resilience engineering studies how pergalan fail, how failures can be prevented and how systems absorb, adapt and recover from disruption. It addresses both technical components and the organisations that operate them. In binesaziya girîng and cities and built environment, resilience engineering identifies critical components and recovery bottlenecks across connected systems. It informs redundancy, spares and restoration priorities. The canonical description is on STEM Commons.
Service performance over time during and after disruption is described by robustness, rapidity of recovery and lost service, so that interventions can be compared on the same curve.
Component failure rates and network structure are combined to estimate service availability, and the components that dominate unavailability are identified.
Crews, spares and access are modelled to estimate restoration curves, and options to shorten them are compared.

Reliability predictions are compared with field failure data. Exercises and post-event reviews check whether recovery performed as planned.
| Kontrol bikin | How it is done |
|---|---|
| Back-casting events | Models reproduce outage and restoration patterns of past events |
| Common-cause review | Redundant elements are checked for shared failure causes |
| Operator review | Assumptions about crews and spares are confirmed with operators |
Common-cause failures and rare events are hard to estimate from limited data. Human and organisational factors resist quantification.
