基于混合交叉作业的集装箱物流码头调度问题研究

摘要

In this paper, on the basis of the overall operational achievement of container terminals, we considered the relationship between the dynamic berth allocation, handling activities and loading/unloading processes in the workings of the container logistics terminals, proposed the optimized dispatching solution based on the hybrid crossover activity system, built the relevant container terminal dispatching model, designed the bi-level genetic algorithm for the solution of the model, and at the end, through an empirical study, verified the effect of the model and algorithm proposed in this paper.%以集装箱物流码头的整体运营效益为基础，考虑了集装箱物流码头生产作业过程中的泊位动态分配、搬运作业、装卸过程等各个重要环节之间的关系，提出了基于混合交叉作业体系的调度优化方案，建立了集装箱物流码头调度问题模型，并设计了求解此类问题的双层遗传算法，算法解决了物流码头的设备资源的合理配置和集装箱卡车的线路优化问题。通过实例分析，验证了所提出的基于混合交叉作业的模型和算法的应用效果，能充分提升集装箱物流码头的生产作业效率，有效控制了码头运营费用，为集装箱物流码头的调度优化问题提供了决策支持。
