弱连接视角下供应链中断风险传导特性分析
Analyzing Risk Transmission Properties of Supply Chain Disruption from the Perspective of Weak Ties

在弱连接视角下，考量供应链中断风险传导通道与密度、传导鲁棒性、传导路径、传导范围和传导速度等五个方面特性与数值模拟。结果表明：弱连接关系的引入可以增加供应链中断风险传导通道与密度，可增加各节点企业的度值，使度分布趋于均匀化；WS小世界网络结构能建立更短的中断风险传导路径，增加各节点企业间的深层次沟通次数。
This paper introduces the theory of weak ties and its strengths in network analysis, and investigates the complexity of risk transmission of supply chain disruption, and also explicates the characteristics of small world in the process of risk transmission of supply chain disruption. From the perspective of weak ties, the detailed analyses of properties have been provided in five aspects: channels and density of risk transmission of supply chain disruption, and transmission robustness, routes, range and speed, together with the numerical simulation analysis, and then some specific suggestions are considered.
