GCRI · 系统性风险管理
韧性工程
Resilience engineering studies how 系统 and organisations keep functioning when conditions exceed what designers expected. It looks at the capacity to anticipate, monitor, respond and learn, and at the margins that let people adapt when procedures run out. This page sets out how resilience is built and eroded, how it can be measured without false precision, and what the evidence serves for those who run critical systems.
Resilience engineering: how the risk develops.
连续性、恢复和 适应能力. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Anticipation and monitoring
Resilient 系统 watch for signals that conditions are changing and prepare before a threshold is crossed. Monitoring that only tracks normal performance misses the drift toward the edge of safe operation.
Margins are traded away
Efficiency pressure removes spare capacity, staff and stock that appear unused. Each removal is reasonable alone, but together they erode the margin that absorbs disruption.
People fill the gap
When procedures do not fit the situation, operators adapt. That adaptive capacity is a source of resilience, and it depends on training, authority to act and time to think.
Learning closes the loop
Organisations that study what went right and what nearly went wrong, as well as failures, adjust designs and procedures. Without learning, the same weaknesses recur.

Resilience engineering looks at how systems adapt, across domains.
- 能源耦合Operators keep grids stable through adaptive control and reserves.What to watchOperator interventions during disturbances
- 卫生耦合Hospitals adapt through surge plans and workarounds when supplies fail.What to watchWorkarounds recorded in after-action reviews
- 水耦合Utilities adapt with alternative sources, pressure management and rationing plans.What to watchContingency supply options
Resilience findings are designed for the Global Sector Risk and Resilience 系列. The discipline, set out by Woods, Hollnagel and colleagues, studies the capacity to respond, monitor, anticipate and learn; evidence comes from operations and exercises, recorded under NS-11 of the proposed Nexus Standards.
- Operational accounts of how staff kept a service running.
- Exercise records with independent evaluation.

- Resilience assessments organised around anticipating, monitoring, responding and learning
- Margin inventories that show where spare capacity has been removed
- Exercise designs for degraded and manual operation
- Learning reviews that cover near misses and successful adaptation
What resilience engineers ask.
- Which services must continue under any disruption, and what is the longest interruption they can tolerate?
- How does the system degrade under stress: gracefully, or suddenly?
- How quickly can it recover, and what does recovery depend on?
- Can the organisation learn and adapt, or does it repeat the same failures?
Capacities that make systems resilient.
Resilience research distinguishes the capacity to absorb a shock, the capacity to recover from it and the capacity to adapt so that the next shock does less harm. Different investments strengthen each, and an organisation strong in one can be weak in another.
Buffers and margins
Spare capacity, stocks and slack that absorb shocks. Efficiency drives often remove them.
Restoration paths
Plans, spares, skills and relationships that bring services back quickly.
Learning and flexibility
The ability to change how the system works when conditions change, and to learn from near misses.
How resilience is studied and built.
- 01
- 02
Business continuity analysis
Identifies critical services, tolerances for disruption and dependencies. It depends on honest assessment of what is truly critical.
- 03
韧性指标
Measures such as time to recover and service level under stress. No single metric captures resilience, and metrics can be gamed.
- 04
Learning reviews
Studies of how work is actually done, including successful adaptation, not only failures. They require a culture that does not punish honesty.
