AI Technical Summary

Technical Problem

Existing ship-finding methods mainly rely on AIS information and predictions of historical navigation tracks, which cannot effectively eliminate the impact of uncertainties in bulk carrier transportation, such as cargo conditions, weather conditions, and port operation efficiency, resulting in low accuracy and efficiency in ship-finding.

Method used

A four-step funnel filtering method is adopted, which divides user demand information into regions, events, attributes, goods and reachability information, and combines electronic fence algorithms and offer information to progressively filter ship information, including the screening process of initial candidates, candidates, offer candidates and target ships.

Benefits of technology

It improves the accuracy and efficiency of ship locating, reduces unnecessary information processing through multi-dimensional demand screening, ensures that ship selection meets user needs, and improves the accuracy and time calibration of ship locating.

Abstract

The invention relates to an efficient ship finding method, device and equipment based on a four-step funnel filtering method and a medium, and is applied to the technical field of ship screening. Dividing the user demand information into first demand information, second demand information and third demand information; screening the ship operation information based on the first demand information to obtain at least one piece of initial candidate ship information; screening the initial candidate ship information based on the second demand information to obtain at least one piece of candidate ship information; acquiring offering information, wherein the offering information comprises pre-empty time and a pre-empty port of the ship; screening the candidate ship information based on the third demand information and the pre-empty time to obtain offer candidate ship information; and screening the offer candidate ship information based on the pre-empty port to obtain target ship information. The ship searching method and device have the effect of improving the ship searching accuracy and efficiency.
