摘要
针对集装箱堆场快速、高效装船作业的实际需求,结合集装箱码头作业状况深入分析了倒箱产生的原因。基于给定的堆场集装箱堆存状态和集装箱装船配载图,研究堆场集装箱装船顺序确定问题,提出了一种以最小化倒箱量为目标的集装箱装船顺序的启发式算法,建立了基于规则的改进策略。最后用实例证明了算法的准确性和实用性,能够为集装箱码头装船作业提供决策依据,从而提高其作业效率和服务质量。
In a yard where export containers are piled up,only those on the top are directly accessible to the stacking equipment.As a result,extra relocations may occur when lifting them up for loading onto ships.One way to improve operational efficiency is to get an optimized container loading sequence in advance.The causation of relocation was analysed in consideration of container yard reality.Based on given information of the container storage in the container yard and container ship stowage plan,this paper proposed a model for container loading sequence problem and aimed to get least relocations.The proposed heuristic and its improvement of rule-based strategies were presented.Several sets of testing results demonstrate the performance of the heuristic algorithm accuracy and practicality.This method can provide the decision making basis for container loading operation.
