摘要
日益大型化的集装箱船舶对集装箱码头的生产调度提出了较以往更加严格的要求。集装箱码头中的集卡调度是否合理对于提高整个码头的装卸效率具有重要意义。利用agent和哈佛体系结构对集卡动态调度进行建模,以AnyLogic仿真平台为实现工具,基于数据库中实际的生产数据,融合黑板系统和消息通讯形成多agent之间的协同机制,引入操作系统中的资源分配算法调度集卡。最后仿真了具体的港口生产实例,其结果优于以往文献的仿真结果,充分验证了上述建模仿真思想的可行性和可信性。
The increasing large-scale container ship advances the more crucial requirement to container terminal scheduling system than ever. Whether vehicles dispatching at container terminals is rational or not is provided with important significance to improve the whole handling efficiency. The model framework of vehicle dynamic dispatching on the basis of multi-agent and Harvard architecture was proposed. Subsequently, the simulation of the above model on the AnyLogic was discussed in detail. The practical operational data stored in the database were engaged to drive the simulation,＂ the blackboard system and messagelconversation were fused to form the communication mechanism in the simulation; the resource allocation policies and algorithms in operation system were introduced to schedule vehicles.Finally, a nmning instance in port was simulated whose result excels the previous data to validate the feasibility and creditability of the methodology.
