摘要: 为缓解快递网络转运枢纽的拥堵以及降低网络中断后的影响,以传统的轴辐式网络结构为基础,考虑由于枢纽拥堵产生的拥堵代价和拥堵时间,引入备份枢纽策略保障网络能够在中断后继续运行,以最小化正常和枢纽失效下的网络总期望成本为目标,建立了考虑枢纽拥堵和失效影响的快递网络优化模型。针对选址问题特点以及传统遗传算法深度搜索能力较弱的问题,设计了具有6种邻域结构的变邻域遗传算法(variable neighborhood genetic algorithm,VNGA),并基于Turkey网络数据集进行求解。在节点数为15的算例下,VNGA与粒子群算法、模拟退火算法求解结果的平均Gap值分别为?3.99%、?2.55%。最后对模型在两种不同情形下的结果进行分析,结果表明,同时考虑枢纽拥堵和失效影响的快递网络更为可靠。

Abstract: In order to alleviate the congestion of the transport hub of the express network and reduce the impact after network interruption, based on the traditional hub-and-spoke network structure and considering the congestion cost and congestion time caused by hub congestion, a backup hub strategy is introduced to ensure that the network can continue to operate after disruption, with the goal of minimizing the total expected cost of the network under normal and hub failure conditions. An optimization model of express network considering the impact of hub congestion and failure is established. Aiming at the characteristics of the location problem and the weak deep search ability of traditional genetic algorithms, a variable neighborhood genetic algorithm with 6 kinds of neighborhood structures is designed and solved based on the Turkey network dataset. The average Gap values of VNGA, particle swarm optimization and simulated annealing are ?3.99% and 2.55% respectively under the example of 15 nodes. Finally, the results of the model in two different cases are analyzed, and the results show that the express network considering the impact of hub congestion and failure is more reliable.
