Abstract: In order to improve ship scheduling efficiency in bidirectional waterways,alleviate port congestion,and ensure overall operational effectiveness,through the detailed analysis of the channel conflicts in the bidirectional navigable waters,a bidirectional channel scheduling and berth allocation model is constructed. Taking into account factors such as two-way channel conditions,navigation safety protocols,tide riding rules,and berth matching,an integrated optimization mathematical model is established to realize the rational utilization of the two-way channel port resources and improve the port service level.

Key words: two-way channel, big ship tide riding rules, berth type matching, coordination and scheduling, mathematical model
