摘要：

针对高密度作业条件下环形RGV系统运行结构单一、并行能力受限的问题，围绕复杂运行需求下的轨道结构与调度运行机制展开研究。基于AnyLogic平台的Agent建模方法，构建了一种嵌套环形轨道布局的RGV系统仿真模型，在传统环形轨道结构中引入带有变轨装置的内嵌子环。结合铁路行车组织中的区间运行与越行思想，设计了适用于嵌套环形结构的RGV运行与调度规则。仿真结果表明：嵌套环形轨道结构在提升任务并行性、缓解环形轨道运行瓶颈以及支持系统规模扩展方面具有一定优势。相关研究可为复杂环形RGV系统的结构设计与调度策略分析提供参考。

Abstract:

To address the limitations of circular RGV systems under high-density operating conditions, including a simple operational structure and limited parallel operation capability, this study investigates track structures and dispatching mechanisms for complex operational requirements. Based on the agent-based modeling method implemented on the AnyLogic platform, a simulation model of an RGV system with a nested circular track layout was developed, in which an embedded sub-loop equipped with track-switching devices is introduced into the traditional circular track structure. Operating and dispatching rules suitable for the nested circular structure are designed by incorporating the concepts of section operation and overtaking in railway traffic organization. The simulation results indicate that the nested circular track structure offers advantages in improving task parallelism, alleviating bottlenecks in circular track operations, and supporting system scalability. The findings provide references for the structural design and dispatching strategy analysis of complex circular RGV systems.

Key words: automated storage and retrieval system, circular rail guided vehicle, AnyLogic simulation, railway traffic organization, scheduling optimization
