| 摘 要： | 与纯轴辐式运输网络相比,带有直达线路的复合式轴辐式网络可以有效减少货物转运的次数,从而缩短服务时间,减低运营成本.本文以某区域性快运公司为例,将直达线路引入其原有的轴辐式网络,并建立了数学模型,通过选择不同装载容量的车辆并采用遗传算法求解该模型,设计出具有直达线路的混合轴辐式网络.仿真试验结果证明,采用改进后的混合轴辐式网络,该公司的运营成本可降低2.76％.

| Abstract: | Compared with pure hub-and-spoke transportation networks,the hybrid hub-and-spoke system with direct routes can decrease the transshipped freight volume,give shorter service time and reduce the operating costs.Taking a regional express freight company as an example,the direct routes were added to its original hub-and-spoke network and mathematical models were proposed.Using a genetic algorithm and specific strategy of choosing vehicle types,a hybrid hub-and-spoke system with direct routes was developed.The ... |
