This paper establishes a progressive optimization-based simulation model for the port-channel-anchorage composite system based on two types of navigation rules for optimizing the number of anchorages. This model determine firstly the value range of the number of anchorages, then find the feasible combinations of the number of anchorages, and finally determine the best combination based on the analysis of comprehensive cost. By taking a large coastal port in China as a case port, this paper presents how to determine the number of anchorages for 300,000-ton berths based on two types of commonly used navigation rules. The case analysis shows that the change of the number of anchorages dedicated to one vessel type not only has a large direct effect on the number of vessels of this type waiting for anchoring, but also indirectly affect the number of vessels of other types waiting for anchoring. This paper also compares the performance differences of the two navigation rules.
