摘要: 在轴辐式网络背景下,枢纽节点通过集散货物,产生规模经济效应来降低成本。但同时也会增加Hub网络拥堵的可能性和成本的增加。首先,为缓解Hub网络拥堵并降低其造成的经济损失成本,提出与轴辐式网络节点流量相关的拥堵成本函数。其次,在保证轴辐式网络节点正常货物运输的前提下,最大限度的平衡货物运输规模经济效应和产生的Hub网络拥堵成本,建立混合整数非线性规划模型,以最小化运输成本、建设成本和拥堵成本为目标。最后,引用实际算例验证Hub网络拥堵对网络优化的影响与模型的合理性。对于未来如何平衡规模经济效应和Hub网络拥堵的轴辐式网络优化有重要的参考价值。

Abstract: In the background of hub and spoke network, hub nodes generated the scale of economic effect to reduce costs by distribution cargo. Meanwhile, it would increase the likelihood of costs increase and Hub network congestion. Firstly, in order to ease the Hub network congestion and reduce its cost of economic loss, the congestion cost function associated with the node flow in the Hub and spoke network was proposed. Secondly, under the premise of ensuring the normal cargo transportation of the axis and radial network nodes, the balance between the economic effect caused by the scale of goods transport and the caused hub network congestion costs was maximized, and the mixed-integer nonlinear programming model was established to minimize transportation costs, construction costs and congestion costs. Finally, a case study was carried out to verify the influence of Hub network congestion on network optimization and the reasonableness of model, which had important reference value for balancing the scale economic effect and the Hub and spoke network optimization of Hub network congestion in the future.
