       The berth queuing pricing model is used to disperse the ship’s over-intensive arrival status, and consequently relieve the ship queuing phenomenon. In the existing model, the value of the queuing time cost of the ship is the same, and the ship registration time requirement is the precise time spot. However, in the maritime practice status, the queuing time cost of the ship varies due to different types of properties, and the ship registration time also has a buffer flexible period. In view of this, this study considers the difference in the queuing time cost of ships, and relaxes the ship registration time to be a time period to reconstruct the berth queuing pricing model. This improved model first calculates the equilibrium cost of the ship before implementing the toll, then we can derive the optimal time-varying flexible toll scheme and step flexible toll scheme. Finally, using the relevant statistics of Kaohsiung Port to write a program for a numerical analysis of the effects of the above toll schemes on ship queuing reduction.
