摘要: 基于Extendsim仿真软件建立了单船装卸作业模型,研究了在双目标(船舶装卸效率和机械使用效率均达到最大化)约束下的机械最优配比和离散状态下的桥吊效率配置优化问题。研究发现:通过实时记录方法研究最优机械配比问题更加直观和方便;双目标约束下的机械最优配比与单目标约束下的机械最优配比存在较大差异,前者得到结果更为合理;由于桥吊作业的离散化特征,仿真过程中对桥吊效率进行平均处理对结果影响较大,影响度随着桥吊效率离散程度的增大而增大。研究结果为集装箱码头机械配置决策提供了参考。

Abstract: The optimization of the machinery allocation under the double constraints of maximized efficiency for loading and unloading processes and optimal machinery usage, and the optimal configuration of bridge cranes under discrete operation modes for a single ship were instigated through modeling with the simulation software Extendsim. It was found that the real-time recording method is a more straightforward and convenient way to investigate the optimal mechanical configuration and double constraints lead to different but more reasonable results than that was obtained under the single constraint on the best mechanical configuration. Due to the discrete characteristics of the bridge crane operation, the averaging treatment has an important influence on the efficiency and such impact becomes stronger with higher discreteness. This simulation work offers valuable references for machinery configuration of container terminals.
