由于我们的全球社会越来越多地发生破坏，了解不同社会经济系统的恢复能力变得至关重要，即，这些系统在多大程度上展示了抵抗破坏和从破坏中恢复的能力。然而，为了描述这种能力，必须能够定量地测量给定系统在响应破坏性事件时显示的相对弹性水平。这样的测量应该容易理解和直接实现，但它也应该利用一致的参考框架，以便人们可以适当地比较不同系统的相对性能，并评估不同弹性投资的相对有效性。考虑到这一点，本文提出了一种用于度量系统弹性的改进方法，通过提供跨不同上下文的一致性和灵活性来支持更好的决策制定。本文首先阐述了该方法的理论基础，然后通过几个不同的实例说明了该方法的优点和局限性。
Due to the increasing occurrence of disruptions across our global society, it has become critically important to understand the resilience of different socio-economic systems, i.e., to what extent those systems exhibit the ability both to resist a disruption and to recover from one once it occurs. In order to characterize this ability, however, one must be able to quantitatively measure the relative level of resilience that a given system displays in response to a disruptive event. Such a measurement should be easily understandable and straightforward to implement, but it should also utilize a consistent frame of reference so that one can properly compare the relative performance of different systems and assess the relative effectiveness of different resilience investments. With this in mind, this paper presents an improved approach for measuring system resilience that supports better decision making by providing both consistency and flexibility across different contexts. The theoretical basis for the approach is developed first, and then its advantages and limitations are illustrated in the context of several different practical examples.
