Ship route recommendation method

Abstract

A ship route recommendation method comprises the steps of obtaining AIS historical data of a ship, screening a mileage and speed optimal value route according to port information, ship information, time information, meteorological information and crossing nodes of the ship, and recommending the optimal route. The recommendation method further comprises the steps of restoring a ship trajectory on an electronic chart according to the AIS historical data, predicting a ship route comprising the navigation destination in real time by utilizing a recommendation and trajectory restoration algorithm,and dynamically updating the prediction result in time based on the actual operation data of the ship.

Description

technical field [0001] The invention belongs to the technical field of ship shipping, and in particular relates to a method for recommending ship routes. Background technique [0002] The current mainstream route recommendation algorithms between ports, represented by layered network and ant colony algorithm, try to make some achievements in route dynamic planning. These algorithms or academic papers mainly have the following problems: [0003] Focusing only on domestic coastal ports, they do not have the ability to plan global port routes, which is not in line with the current globalization of the shipping industry and the development needs of informatization and intelligence, such as intercontinental route planning, strait crossing, and length route supply node recommendation; [0004] Dynamic route planning is only theoretically feasible, that is, the accessibility of several physical nodes, and the recommendation results are not supported by enough actual data cases; ...

AI Technical Summary

Problems solved by technology

[0005] The input factors of the route planning algorithm cannot be fully considered. In fact, different ship types, deadweight tons, weather, ocean currents, tides and even seasonal factors will affect the recommendation results, especially when planning international routes and long-distance routes;
