基于复杂网络理论的物流服务供应链网络脆弱性机理研究

文章针对现实运作物流服务供应链网络系统的复杂性与关联性，对物流服务供应链复杂网络脆弱性进行研究。首先，在对供应链脆弱性进行归纳的基础上阐述物流服务供应链局域网络演化机理及拓扑结构特征，描述其复杂网络统计参数；其次，从供需结构复杂性、突发事件风险情景、无标度性及级联故障等方面揭示物流服务供应链网络脆弱性机制；最后，借鉴复杂网络中节点冗余、弱连接、结构均匀性及免疫策略等理论提出物流服务供应链网络脆弱性的防范对策。研究结论对节点企业采取有效防范措施保证物流服务供应链网络效率具有重要意义。

Mechanism of Network Vulnerability of Logistics Service Supply Chain Based on Complex Network Theory

Based on the complexity and relevance of logistics service supply chain (LSSC) network system, the network vulnerability of LSSC is analyzed. First of all, the research analyzes the vulnerability of Supply Chain, complex topological characteristics and local area specific evolution mechanism of logistics service network. Secondly, the vulnerability mechanism of LSSC network is revealed in terms of supply and demand network complexity, emergency risk, non-scaling and cascading failures. At last, based on such theories as redundant nodes, weak ties, distribution uniformity and immunization strategy, preventive measures are put forward. This research is significant for enterprises taking effective preventive measures to guarantee efficiency of LSSC network.
