Research on Multi-Agent system of container reception and distribution management of container yard

考虑集装箱码头堆场管理的动态性、复杂性和分布式特点,在对集装箱堆场作业工艺分析的基础上,建立了堆场收发箱管理Multi-Agent系统模型,系统地分析了Agent基本结构和功能,分别基于两级调度策略和翻箱期望最小设计了收、发箱箱位优化Agent,提出了Agent间的通信和协作机制.算例仿真表明该系统能有效改进收发箱管理性能.

Considering dynamic characteristics, complexity and distributed characteristics of container storage yard management, a Multi-Agent system （MAS） model of container reception and distribution management of container yard is established based on the analyses of container yard operation process. Then, the basic structure and function of the agents are analyzed systematically. And the slot allocation optimization agent is implemented with two optimization methods, one of which is for outbound containers and based on the two-levels scheduling strategy, and the other is for inbound containers and based on minimal reshuffling expectation. Afterwards, the mechanism of communication and coordination among agents are proposed. Finally, simulation examples show that the proposed MAS can improve the performance of container reception and distribution management effectively.
