摘　　要：针对物流系统极易受突发风险影响而出现运输停滞的问题,提出实时监测、快速恢复的策略,根据物流业务特点构建适用于量化负载的物流网络,结合传染病系统方程提出风险触发的网络状态监测算法,通过节点拓扑权重和风险波动建立风险扩散机制。基于扩散机制考虑风险在网络中传播的影响,以节点重要性为衡量指标指导限定资源的分配,从而实现物流网络的恢复算法。最后,依据最短路径长度设计了网络效率指标,通过算例验证了该算法最高可将恢复时间缩短69.38%,对缩短网络恢复时间、降低延误损失具有参考意义。In response to the issue of transport stagnation in the logistics system,which is vulnerable to sudden risks,a strategy for real-time monitoring and rapid recovery is proposed.A logistics network suitable for quantified load was established based on the characteristics of the logistics business.Additionally,a risk-triggered network state monitoring algorithm was introduced,combined with an infectious disease system equation,and a risk diffusion mechanism was established through node topology weights and risk fluctuations.Based on the diffusion mechanism,considering the impact of risk propagation in the network,node importance was used as a measure to guide the allocation of limited resources in order to realize the restoration algorithm of the logistics network.Finally,a network efficiency index was designed based on shortest path length.An example verifies that maximum recovery time can be reduced by 69.38%,providing valuable insights for shortening network recovery time and reducing delay loss.
