AGV is an equipment of the horizontal transportation,and is mainly responsible for the transportation of containers.Due to the factors of the loading capacity of QCs and YCs,the distance of horizontal transportation and the increasing capacity of container,the horizontal transportation is the bottleneck which restricts the development of the automated terminal.Combined the actual operation of the terminal,we adopt the method of “model + instance + simulations” to study the AGV path optimization problem of automation terminal problem.We combined with the theory of road traffic flow,and put forward the virtual traffic circle strategy to avoid conflict and congestion of AGVs.Under the unloading process,we use the eM-Plant simulation software to simulate the traffic control strategy from different views.Experiment results show that the different AGV paths affect the working efficiency of automated terminal.And it can further improve the efficiency of terminal operation,and provide certain reference for AGV path optimization in automation terminal.
