建立了天然气管网脆弱性评价的系统框架。为了衡量事故对燃气供应服务的影响，后果模型的基础上，嵌入到一个优化方案的流量算法，考虑物理约束。脆弱性分析从三个角度进行：全球脆弱性分析，需求稳健性和关键管道分析。从气源、需求和输气系统的危害和威胁出发，进行了全球脆弱性分析。需求鲁棒性分析评估需求站点承受施加在管道网络系统上的压力的能力，并从图论的角度进一步解释能力的差异。在关键管道分析中，通过考虑直接攻击和使用基于物理流的方法来评估管道的关键性。分析是在一个相对复杂的天然气管网上进行的。
A systematic framework is developed to assess the vulnerability of natural gas pipeline networks. To measure the impact of accidents on gas supply service, a consequence model is developed based on a flow algorithm embedded into an optimization scheme, with the consideration of physical constraints. The vulnerability analysis is performed from three viewpoints: global vulnerability analysis, demand robustness and critical pipeline analysis. The global vulnerability analysis is performed considering hazards and threats in gas sources, demand and transmission system. The analysis of demand robustness evaluates the capacities of demand sites to withstand the strains imposed on the pipeline network system and further explains the differences in capacities, from a graph theory perspective. In the critical pipeline analysis, criticalities of pipelines are evaluated by considering direct attacks and using a physical flow-based method. The analyses are performed on a relatively complex gas pipeline network taken from literature.
