基于时效性的物流枢纽拓扑结构脆弱性分析

摘要

To effectively locate the weak link of a logistics hub, to ensure the normal operation and sustainable development of the logistics hub, to utilize the complex network theory, and based on the concept and influence factors of the logistics hub in vulnerability, a logistics hub system vulnerability model was build through analyzing the influence of the disturbance of the logistics nodes and the connecting lines on timeliness of the logistics hub. An instance was taken to analyze the vulnerability of a typical logistics hub topology network. It is showed that the index of fragile degree was comparable and effectiveness, and the method could be used to analyzed the influence of the logistics nodes and the connecting lines in topological structure vulnerability of a logistics hub.%为了能够有效定位物流枢纽薄弱环节，保障物流枢纽的正常运营和可持续发展，运用复杂网络理论，基于物流枢纽脆弱性概念及其影响因素分析，通过因脆弱性使物流结点和联接线路失效后对物流枢纽时效性的影响分析，构建了物流枢纽系统脆弱度模型，并对一个典型的物流枢纽拓扑结构的脆弱性进行实例分析。结果表明脆弱度指标具有可比性和有效性，可用于物流结点及联接线路对物流枢纽拓扑结构脆弱性影响分析。
