摘要: 合理评价物流服务供应链脆弱性是实现网络高效率的重要前提。分析物流服务供应链网络节点作用规律,引入聚集系数、最大连通度及连通效率作为网络脆弱性测度指标,基于所构建攻击策略对二级物流服务供应链网络进行实例研究。研究结果表明:所构建指标可较好描述物流服务供应链网络脆弱性能变化;相较于功能型物流服务供应商与物流客户,物流服务集成商对网络脆弱性影响程度最大。最后提出了物流服务供应链网络脆弱性的有效防范对策。

Abstract: Rational evaluation of logistics service supply chain vulnerability is an important prerequisite to achieve high efficiency of network. Interaction law of internal nodes of logistics service supply chain is analyzed. Network clustering coefficient, largest connectivity and network connectivity efficiency are introduced as measure indicators of network vulnerability. Based on attack strategies, the paper takes two-level logistics service supply chain network as an example to carry on empirical research. Results show that the constructed index can describe vulnerability change of logistics service supply chain network, compared to logistics service provider and logistics customer, logistics service integrator has the biggest impact on network vulnerability. Finally, effective preventive strategies of network vulnerability of logistics service supply chain are put forward.
