Modeling and Simulation of Cold Chain Logistics Network Based on Complex Network Theory

基于复杂网络理论,分析冷链物流网络的特点,引入节点度和接近度作为择优连接的重要参数,同时考虑边退化的情况,建立改进的无标度网络模型,并对其统计特性进行分析。同时对网络节点实施不同的攻击策略,通过计算网络效率和最大连通比,分析网络的鲁棒性。结果表明:冷链物流网络对随机攻击具有一定的鲁棒性,对蓄意攻击表现脆弱。

Based on the complex network theow, this paper analyzed the characteristics of the cold chain logistics network. After introducing node degree and proximity degree as important parameters in connection optimization and at the same time considering edge degradation, it established an improved scale--i＇ee network model and analyzed its statistical characteristics. At the same time, different attack strategies were employed against the nodes of the network, and the robustness of the network was analyzed through calculating the e{-iciency and maximum connectivity ratio of the network. According to the result, the cold chain logistics network showed certain robustness to random attacks but was vulnerable to deliberate attacks.
