In this work, we propose a multi-perspective framework of analysis of critical infrastructures (CIs) with respect to supply service, topology and controllability. The framework enables identifying the role of CI elements and quantifying the consequences of scenarios of multiple failures, with respect to the different perspectives considered. To present the analysis framework, a benchmark network representative of a real gas transmission network across several countries of the European Union (EU) is considered. The information extracted from such analysis can help us to identify the critical elements and how the properties of the network are affected by failures, and to propose corresponding improvements for CIs. The findings of this paper demonstrate the interest of considering several perspectives in the analysis of CIs for providing useful information for ensuring their safe and reliable operation.

在这项工作中，我们提出了一个针对供应链，拓扑和可控性的关键基础设施（CI）分析的多角度框架。该框架能够根据所考虑的不同角度来确定CI元素的作用并量化多重故障场景的后果。为了提出分析框架，考虑了代表欧盟（EU）多个国家的实际天然气传输网络的基准网络。从这种分析中提取的信息可以帮助我们识别关键元素以及网络的性能如何受故障影响，并为CI提出相应的改进建议。
