理解系统复原力并确定增强系统复原力的方法的重要性，特别是对于我们日常生活所依赖的相互依赖的基础设施，不仅得到了学术界的认可，而且也得到了企业和公共部门的认可。近年来，一些方法和框架已被提出和发展，以探索适用的技术，以全面的方式评估和分析系统的弹性。然而，它们往往是针对特定的破坏性危害/事件定制的，或未能适当地包括吸收、适应和恢复等所有阶段。本文提出了一种定量评估系统弹性的方法。该方法由两部分组成：一个综合指标的系统弹性量化和混合建模方法表示基础设施系统的故障行为。所提出的方法的可行性和适用性进行了测试，使用电力供应系统作为示例性的基础设施。仿真结果表明，该方法在基础设施的设计、工程和提高弹性方面是有效的。最后，系统弹性被提出作为一个代理，以量化相互依赖的基础设施之间的耦合强度。(C)2016爱思唯尔有限公司版权所有
The importance of understanding system resilience and identifying ways to enhance it, especially for interdependent infrastructures our daily life depends on, has been recognized not only by academics, but also by the corporate and public sectors. During recent years, several methods and frameworks have been proposed and developed to explore applicable techniques to assess and analyze system resilience in a comprehensive way. However, they are often tailored to specific disruptive hazards/events, or fail to properly include all the phases such as absorption, adaptation, and recovery. In this paper, a quantitative method for the assessment of the system resilience is proposed. The method consists of two components: an integrated metric for system resilience quantification and a hybrid modeling approach for representing the failure behavior of infrastructure systems. The feasibility and applicability of the proposed method are tested using an electric power supply system as the exemplary infrastructure. Simulation results highlight that the method proves effective in designing, engineering and improving the resilience of infrastructures. Finally, system resilience is proposed as a proxy to quantify the coupling strength between interdependent infrastructures. (C) 2016 Elsevier Ltd. All rights reserved.
