基于仿真的船舶分段建造动态空间调度

Simulation-based Ship Block Building Dynamic Spatial Scheduling

为缩小船舶分段空间调度计划与实际作业安排之间的差别,提出了一种基于仿真的船舶分段建造动态空间调度方法。针对分段建造的不同阶段,在分析影响因素的影响形式基础上提出了动态调整策略,包括定位延时策略、进度控制策略和吊运等待策略,调整分段建造过程以适应影响因素的作用。构建了船舶分段建造仿真模型,实现了分段建造在影响因素作用下动态空间调度的仿真。以实际数据为输入进行仿真分析,结果表明,该方法制定的调度计划与实际作业情况接近,且能够为分段生产计划优化调整提供指导。

To reduce the difference among ship block spatial scheduling results and actual working assignments,a simulation-based dynamic spatial scheduling method was proposed. According to differ- ent stages of ship-block building and analyzing the influence forms of affecting factors, three dynamic adjustment strategies were put forward, including positioning delay strategy,progress control strategy and swing waiting strategy. With these strategies,the ship-block building processes could be adjusted so as to adapt to affecting factors. A ship bloek building simulation model was developed to realize the dynamic spatial scheduling simulation under the influence of affecting factors. The simulation results indicate that the proposed method can reduce the difference between the scheduling plan and actual working ones, and can provide guidance to optimize ship-block building production plan.
