摘要
城市物流和多式联运等往往表现为多级物流网络模式。在多级物流网络上综合运用多种类型的、载运能力不同的车辆,可节约物流成本。在两级物流网络车辆调度运用过程中,货物需要在不同层级的车辆之间进行中转,两个不同层级的车辆路径方案之间需互动协同。由于其实践参考价值和建模求解的复杂性,两级物流网络车辆路径问题(2E-RP问题)相关研究成果在近年来不断涌现。文章梳理总结包括2E-VRP问题、2E-LRP问题、TTRP问题和VRPCD问题等在内的2E-RP问题的研究进展;基于2E-RP问题所对应的行业实践背景,为拓展2E-RP问题数学建模思路,提出促使两个层级车辆路径互动的新的驱动因素,即时效和运力匹配;指出后续研究2E-RP问题时可在建模方面的关注点。
The type of distribution systems for city logistics and multi-modal transportation systems is commonly called multi-echelon logistics network.Various vehicles with different capacities are employed on the multi-echelon logistics network,which may save costs.In two-echelon distribution systems,cargoes are transferred between vehicles for different echelons,and routes of the two echelons are interacted with each other.Due to its practical reference and complexity of models and algorithms,the two-echelon routing problem(2E-RP)has inspired an ever-growing amount of literature in the past decades.An overview of the 2E-RP is provided in this paper.Four classes of problems are considered:the 2E-VRP,the 2E-LRP,the TTRP and the VRPCD.Considering the corresponding practical background of the 2E-RP,the time-constrained requirement and the capacity matching of multi-type vehicles are suggested as key factors for mathematical models to promote the interactions between the routes of the two echelons.Finally,some promising research directions for models of the 2E-RP are proposed.
