Abstract:

Railway container yard is a buffer area of loading and unloading freights between train and truck. The storage efficiency thus significantly impacts the performance ability and productivity of railway container terminal. This paper examines the optimization problem of mixed storage in railway container terminal and proposes a twostage optimization model considering the description of mixed storage operation in container yard. In the first stage, output and input container volumes are balanced among various blocks. To reduce the container overlapping amounts, the relative optimal slots are allocated in the second stage. The algorithm to solve the problem is presented based on heuristic algorithm. The field data from certain railway container terminal is used to test the proposed method and the result shows its effectiveness and efficiencies.

Key words: railway transportation, mixed storage optimization, heuristic algorithm, container terminal, container yard

摘要:

铁路集装箱中心站堆场作为集装箱列车装卸作业与集卡提交箱作业的缓冲区,堆存策略直接影响整个中心站的作业能力和效率,本文对铁路集装箱中心站堆场混堆优化问题进行了研究.根据中心站堆场混堆作业问题的描述,建立了两阶段优化模型,第一阶段平衡中心站堆场各箱区进口箱和出口箱的箱量,第二阶段为分配到箱区的集装箱指派较优箱位,使堆存所产生的压箱数最小,并设计了启发式算法对模型进行求解.最后利用某集装箱中心站的实际数据对模型和算法进行了验证,验证结果表明,该优化模型比中心站现有的堆存策略有较大改进.
