摘　　要：随着我国铁路路网规模提升以及行车密度加大,铁路对安全运行的要求更加严格。为进一步提高调度系统的安全保障能力,以铁路施工调度为例,建立铁路施工调度流程知识图谱,以准确刻画施工调度过程中所涉及的人员、设备、文件之间的相互关系,并构建该知识图谱的有向加权网络模型。在此基础上,利用复杂网络理论统计该网络的度分布数据,证明该网络具有无标度网络性质,得出该网络中具有在统计特征上明显有别于其他节点的关键节点且需要进行识别,进而设计基于网络中节点的度与介数指标的关键节点评价方法,实现影响网络传播效率变化的关键节点识别,并给出针对特定节点的管理建议。研究成果可为铁路运营管理决策者进行调度安全分析提供决策支撑方法。As China’s railway network expands and traffic density increases,the railway operation safety requirement has become more stringent.To improve the safety assurance capabilities of dispatching system,the paper uses the railway construction dispatching as a case study and creates a knowledge graph of the dispatching process.The aim is to accurately illustrate the relationships between personnel,equipment,and documents involved in the construction dispatching process and develop a directed weighing network model of the knowledge graph.Furthermore,a complex network theory is used to analyze the degree distribution data of the network,proving that it possesses scale-free properties.The study concludes that there are key nodes within the network that statistically differ from other nodes and require identification.A method was designed for identifying key nodes based on degree and betweenness indicators of network nodes.This method aims to identify the key nodes that influence changes in network communication efficiency.Additionally,it offers management recommendations for specific nodes.The research findings offer a decision support method for railway operation management decision-makers in dispatching safety analysis.
