【摘要】：甩挂运输作为一种新兴的运输模式,对于提高车辆运行效率、降低物流运输成本、促进节能减排、推动绿色物流发展具有重要意义。2010年政府开始加大推广甩挂运输力度,明确将“推行公路甩挂运输”作为重点领域的节能减排任务。随着政府推广和扶持力度的加大,各地广泛开展公路甩挂运输,我国甩挂运输的发展开始慢慢步入正轨。 LPG作为一种清洁能源,未来市场前景广阔,但目前LPG运输调度的优势主要集中在罐式集装箱的多式联运,而公路运输在LPG的整个运输过程中占有较大比重,公路运输成本却一直居高不下,针对目前LPG发展所面对的机遇与挑战,本文将新兴的甩挂运输模式运用于LPG的公路运输过程,以期提高LPG公路运输的效率、降低运输成本,提高LPG在清洁能源市场的竞争力。 本文从LPG的产量、场站布局、自身特点以及政府对甩挂运输的的扶持政策等角度分析了LPG开展公路甩挂运输的必要性,并为其选择了合理的甩挂运输组织形式。针对目前LPG内陆分布的各场、站、库节点的货运需求,经过合理的假设建立了数学模型。模型主要解决的问题是：在每辆牵引车每天具有最大行驶里程限制、各取货节点(甩挂对前点)具有取货时间窗限制的条件下,如何开展LPG循环甩挂运输,能够使完成整个运输任务的总成本最少,并且使牵引车的投入数量最少。模型采用禁忌搜索算法进行求解,最终给出LPG循环甩挂运输调度的合理方案。
[Abstract]:As a new mode of transportation, swing and hang transportation is of great significance to improve the efficiency of vehicle operation, reduce the cost of logistics transportation, promote energy saving and emission reduction, and promote the development of green logistics. Specifically, the implementation of road transport as a key area of energy conservation and emission reduction task. With the increase of government promotion and support, highway transportation is widely carried out. As a kind of clean energy, LPG has a broad market prospect in the future. But at present, the advantages of LPG transportation scheduling are mainly concentrated in the multimodal transport of tank containers, and road transportation occupies a large proportion in the whole process of LPG transportation. However, the cost of highway transportation has been high all the time. In view of the opportunities and challenges facing the development of LPG at present, this paper applies the new mode of jettisoning transportation to the road transportation process of LPG in order to improve the efficiency of LPG highway transportation and reduce the transportation cost. Improve the competitiveness of LPG in the clean energy market. This paper analyzes the necessity of LPG transportation in highway from the point of view of output, station layout, its own characteristics and the government's supporting policy to swing and hang transportation, and selects a reasonable form of transportation organization for it. According to the freight demand of each field, station and storage node in the inland distribution of LPG at present, the mathematical model is established through reasonable assumptions. The main problems solved by the model are: how to carry out LPG cycle swing transportation under the condition that each tractor has the maximum mileage limit every day, and each pick-up node has the time window limit. The total cost of completing the whole transportation task and the quantity of the tractor input can be minimized. Tabu search algorithm is used to solve the model, and finally a reasonable scheme of LPG cyclic swing and hang scheduling is given.
