In order to adapt to the increasing throughput of ports and the trend of large-scale development of container ships,new forms of layouts and operation modes of container terminal have emerged.The high-bay storage system(HBS),as a storage solution that reduces land usage by increasing storage density,provides new ideas for the development of three-dimensional storage yards.In response to the construction requirements of conserving and intensively utilizing land resources,we take the high-bay storage system as an research object.By considering the complexity and uncertainty of its operation process,we build an intelligent agent simulation model for the HBS operation,verify its effectiveness,and analyze the efficiency of yard crane operations under different working conditions,which can provide decision support for the reconstruction of container yards in China.
