关键基础设施系统各组成部分的复原力是决定关键基础设施系统向社会提供的服务和商品是否可靠的一个主要因素。复原力可以被视为一种品质，它减少了一个元素的脆弱性，吸收破坏性事件的影响，提高了元素的反应和恢复能力，并促进其适应类似于过去遇到的破坏性事件。在这方面，复原力评估不仅在确保这些要素本身的安全和可靠性方面，而且在确保整个系统的安全和可靠性方面发挥着重要作用。本文介绍了CIERA的关键基础设施要素弹性评估方法。这一方法的原则是对关键基础设施要素的复原力水平进行统计评估，包括对其坚固性、在发生破坏性事件后恢复功能的能力以及适应先前破坏性事件的能力进行综合评价。因此，这一复杂办法既包括评估技术和组织复原力，也包括查明薄弱环节，以加强复原力。CIERA方法的应用的一个例子是以案例研究的形式提出的，重点是评估电力能源基础设施的选定元素的弹性。(C)2019作者出版社：Elsevier B.V.
The resilience of elements in a critical infrastructure system is a major factor determining the reliability of services and commodities provided by the critical infrastructure system to society. Resilience can be viewed as a quality which reduces the vulnerability of an element, absorbs the effects of disruptive events, enhances the element's ability to respond and recover, and facilitates its adaptation to disruptive events similar to those encountered in the past. In this respect, resilience assessment plays an important role in ensuring the security and reliability of not only these elements alone, but also of the system as a whole. The paper introduces the CIERA methodology designed for Critical Infrastructure Elements Resilience Assessment. The principle of this method is the statistical assessment of the level of resilience of critical infrastructure elements, involving a complex evaluation of their robustness, their ability to recover functionality after the occurrence of a disruptive event and their capacity to adapt to previous disruptive events. The complex approach thus includes both the assessment of technical and organizational resilience, as well as the identification of weak points in order to strengthen resilience. An example of the application of the CIERA method is presented in the form of a case study focused on assessing the resilience of a selected element of electrical energy infrastructure.
