The Yangshan Phase IV automated terminal is currently the world’s largest single-scale automated container terminal with the highest degree of automation integration. The design throughput of the initial stage is 4 million TEU，and it can eventually reach 6.3 million TEU. The water-to-water transfer ratio of the Yangshan Phase IV container terminal is as high as 50%. To meet the efficiency of loading and unloading operations on the seaside of the yard and to ensure the truck transportation on the land side，mixed operations of no cantilever，single cantilever，and double cantilever ARMG were designed in the initial layout design. The AGV not only interacts with the ARMG in the seaside interactive zone but also can go deep into the side of the yard to interact with the single cantilever ARMG，which improves the efficiency of loading and unloading operations at the waterside of the yard. Based on this operating condition，relevant design scheme research was carried out. Based on the layout design of the cantilever yard，the AGV path rules，and related technical difficulties in the operation process，this paper systematically analyzes and elaborates the scheme.
