Research on one-way channel conversion strategy of coastal ports based on system simulation

The waterway is the necessary passage for ships to enter and leave the port. From the perspective of cost, many coastal port channels are one-way channels, it alternates as an inbound channel and an outbound channel. The oneway channel conversion strategy refers to when it is used as an inbound channel and when it is used as an outbound channel. By constructing a simulation model, this paper simulates the one-way channel conversion strategy that uses a fixed time period conversion, a conversion considering a certain number of outbound ships, and a conversion with the combination of time and number of outbound ships to achieve the best state of the port's overall operations. By comparing the port service level, traffic capacity of waterway, ships waiting time and other indicators, a one-way channel conversion strategy suitable for port operations is recommended.
