网络型甩挂运输模式下的车辆调度问题

研究甩挂运输的车辆调度问题对于提高运输效率、节约运输成本具有重要意义。本文在总结归纳甩挂运输组织模式的基础上,对网络型甩挂运输车辆调度问题进行研究。网络型甩挂运输属于满载多车场车辆调度问题,本文结合甩挂运输及满载多车场车辆调度问题的特点,建立了数学模型、设计了相应算法,并通过具体算例进行分析。算例结果表明,经过合理的车辆调度,更能发挥甩挂运输节能减排的优势。

Research of Vehicle Scheduling Problem of the Network Drop and Pull Transport

At present,there is a few researches on drop and pull transport vehicle scheduling problem（VSP）in our country, but this research has great significance in improving transportation efficiency and saving the cost of transportation.On the basis of summarizing the drop and pull transport organization modes, VSP of the network drop and pull transport has been studied. According to the classification of the VSP, the drop and pull transport VSP belongs to multi-depot and full-load transportation VSP. Combining with the characteristics of drop and pull transport with the multi-depot and full-load transportation VSP’s, a mathematical mode was established in this paper and the corresponding algorithm was designed, and a concrete example was analyzed at the end. The example results showed that reasonable vehicle scheduling would give full play to the advantages of drop and pull transport’s energy conservation and emissions reduction.
