“…Extensive research on system resilience has still not resulted in a standard definition of resilience, or a consistent approach for quantifying resilience [Sheard and Mostashari, ]. We quote and paraphrase the following definitions of resilience: - The ability to restore a system from a disrupted state to a stable recovered state [Henry and Ramirez‐Marquez, ].
- A time‐dependent ratio of recovery over maximum loss [Barker, Ramirez‐Marquez, and Rocco, ].
- Resilience is that of emergence, which means that simple entities, because of their interaction and feedback, their cross‐adaptation, and cumulative change, can produce far more complex behaviors as a collective, and produce effects across scales different from those along which the entities themselves operate [Dekker et al., ].
- “…ability of an entity—for example, asset, organization, community, region—to anticipate, resist, absorb, respond to, adapt to, and recover from a disturbance” [Carlson et al., ].
- Resilience is the ability of an architecture to support the functions necessary for mission success in spite of hostile action or adverse conditions [DOD, ].
