【摘要】 本文讨论了集装箱在堆场的空间分配问题,首先研究建立了前、后方堆场分开堆存进、出口箱的混合整数模型。该模型以最小化集卡行走距离及平衡箱区间作业量为目标,旨在将运进堆场的集装箱直接分配到各箱区贝位中;考虑到便于集装箱码头堆场的实际运作,通过采取在前、后方堆场分别设立缓冲区的方式,以此加速船舶装卸作业及提高堆场空间利用率。然后通过优化软件lingo求解算例,所得优化结果表明该模型不但能实现集卡行走距离的有效减少,同时也保证了龙门吊在箱区间作业量的总体平衡。更多还原

【Abstract】 In this paper the yard space allocation problem of container terminals is addressed.Firstly a mixed integer model which is applied to allocate depot space for export and import containers is established.The model aims to determine the storage bay for the arriving containers with the objective of minimizing the moving distance of trucks and balancing the workload of gantry cranes in the different yard area of the front/rear yard.Considering facilitating the practical operation of the yard,buffer zones are respectively established in the front and rear yard in order to accelerate the loading /unloading operation for vessels and improve the utilization of storage space.Then the optimization software lingo is employed to solve a simulating data case of the problem.The result shows that the method proposed in this paper can not only minimize the total travelling distance of container trucks in the terminal,but also guarantee balancing the workload of gantry cranes in the different yard area of the front/rear yard.更多还原
