Modeling and simulation of lock scheduling considering with ship type standardization for three Gorges-Gezhouba dam cascade hub

In order to analyze the effect of standardization of ship types on the actual throughput capacity of Three Gorges-Gezhouba Dam Cascade Hub, a simulation model based on multi-agent method is established to simulate the whole process of shipping lockage by the Anylogic simulation tool. The main navigation facilities are built in the simulation model to reflect the actual process. Based on operational history data, the experiment with different rates of standardization ship in ship traffic flow are designed. The throughput capacity and chamber utilization area of the cascade reservoirs are calculated in different cases. From the experiment results, it can be seen that the standardization rate of ship type reaches 90% or more, the advantage of standard ship type to improve the operation efficiency of locks is obvious.
