Embodiment 1

[0055] The embodiment of the first purpose of the present invention proposes a method for measuring port congestion, such as figure 1 shown, including:

[0056] S102, counting the total time t of a single ship staying at the anchorage in the port;

[0057] S104, obtaining the median of the anchorage time of historical ships in the port within the preset time period;

[0058] S106, according to the median of the historical anchorage time of ships and the total time t of a single ship at anchorage, calculate the port congestion index of all individual ships in the port according to the preset logarithmic function, and the port congestion index is used to describe the degree of port congestion. The logarithmic function is a logarithmic function about the total time t of a single ship staying at the anchorage;

[0059] S108. Calculate the total port congestion index of all anchored ships in the port according to the port congestion index of all individual anchored ships.

[006...

Embodiment 2

[0100] Based on the ship call data, this scheme designs an index to describe the congestion of port anchorages, which can be used to compare the congestion degree of anchorages at different times in the same port or in different ports at the same time and at different times. The port congestion index is real-time and can monitor ports in real time, which is beneficial for enterprises to choose shipping destinations and transportation methods according to port congestion. For another purpose, the port congestion index can be used for differential analysis of port congestion in designated ports by different shipping companies, and this analysis can also be used as a reference for the selection of shipping companies.

[0101] The method of the present invention can be used in but not limited to the following scenarios:

[0102] (1) Port inspection. For the ports that need to be inspected, first determine the anchorage range of the port, and determine the call data according to t...

Abstract

The invention provides a port congestion degree measurement method and system, a ship, and a port management system, and relates to the field of port traffic. The port congestion degree measurement method includes: counting the total time t of a single ship staying at an anchorage in a port; The median of the anchorage time of historical ships in the period; according to the median of the anchorage time of historical ships and the total time t of a single ship at anchorage, the congestion index of all individual ships in the port is calculated according to the preset logarithmic function, and the congestion index The index is used to describe the degree of port congestion; according to the congestion index of all individual ships at anchor, the total congestion index of all anchored ships in the port is calculated; the total congestion index of the port is equal to the congestion index of all individual anchored ships in the port sum; the preset logarithmic function is: γ=log 1+M (1+t). This application describes the congestion degree of the port by calculating the total port congestion index of the port, so that users can make itinerary arrangements according to the actual congestion situation of the port, and avoid economic losses caused by delays in entering the port.

Description

technical field [0001] The invention relates to the field of port traffic, in particular to a method and system for measuring port congestion, a ship, and a port management system. Background technique [0002] When ships are sailing near the anchorage of the port, they need to line up to enter the port. When there are too many ships piled up at the anchorage of the port, the shipping company needs to choose to skip the port or other transportation methods according to the actual congestion situation and the demand of the cargo type to avoid the economic loss caused by the delay of entering the port. [0003] When approaching a port, affected by factors such as port operation efficiency, number of berths, and weather, ships may need to wait at the anchorage of the port before entering the port. However, due to the influence of many factors, the prediction of the ship’s entry time is still a big problem. The problem. [0004] Therefore, how to propose a scheme that can desc...
