A unifying framework in defining and measuring resilience has been an intense research topic. In this paper, resilience is measured as a function of intrinsic capacities of a system, the effectiveness of recovery, and the extrinsic random shock process. Some existing resilience measures are analyzed as special cases of the proposed unifying measure. Then, we develop a framework in which the key constituents in achieving resilience are identified. Resilience is represented by four key dimensions: reliability, robustness, recovery, and reconfigurability. Finally, some practical and specific strategies are proposed to enhance the resilience of critical infrastructure systems under the proposed framework.

大规模系统的弹性：调查和统一框架

定义和衡量弹性的统一框架一直是研究的热点。在本文中，弹性是根据系统的固有容量，恢复的有效性以及外部随机冲击过程来衡量的。作为建议的统一措施的特例，分析了一些现有的弹性措施。然后，我们建立一个框架，在其中确定实现弹性的关键因素。弹性由四个关键维度表示：可靠性，健壮性，恢复性和可重新配置性。最后，提出了一些切实可行的具体策略，以在所建议的框架下增强关键基础设施系统的弹性。
