在这项研究中，我们分析和比较了几种铁路网的基于拓扑的脆弱性，并使用两种脆弱性标准，即基于全局效率的脆弱性和基于代数连通性的脆弱性来规划预防策略。我们研究了后者作为替代方法的可行性。此外，我们比较了这些脆弱性标准的结果和相关性以及边缘之间的中心性，以分析所有三个指标之间的关系，这些指标考虑了网络中最关键的部分。我们的案例研究是通过合并日本九州的三个主要铁路网获得的，这三个铁路网过去曾因几次自然灾害而暂停运营。这些结果提供了解决方案，从多个角度确定站点中最重要的部分，以管理保护优先事项并进行例行检查或维修。
In this study, we analyzed and compared the topology-based vulnerability of several railway networks to plan a preventive strategy using two vulnerability criteria, i.e., global efficiency- and algebraic connectivity-based vulnerabilities. We studied the feasibility of the latter as an alternative method. Furthermore, we compared the results and correlations of these vulnerability criteria with each other and the edge betweenness centrality to analyze the relationships between all three indicators that consider the most critical sections of networks. Our case study was obtained by combining three main railway networks in Kyushu, Japan, which have suspended operations in the past because of several natural disasters. These results proffer solutions in identifying the most important sections among stations from multiple viewpoints to manage protection priorities and conduct routine inspections or repairs.
