TRFM-LS: Transformer-Based Deep Learning Method for Vessel Trajectory Prediction
TL;DR: In this paper , a trajectory time window panning and smoothing filtering method is proposed for the abnormal values existing in the trajectory data, which can effectively deal with the jump values and outliers in trajectories, make the trajectory smooth and continuous, and ensure the temporal order and integrity of trajectory data.
Simulation on Vessel Intelligent Collision Avoidance Based on Artificial Fish Swarm Algorithm
Weifeng Li,Wenyao Ma +1 more
TL;DR: This paper simulates overtaking situation, crossing situation and head-on situation three classic meeting situation of ships on the sea by VC++ computer language and calculation and simulation results are basically consistent with the actual situation which certifies that its validity.

Vessel scheduling model with resource restriction considerations for restricted channel in ports
TL;DR: Wang et al. as discussed by the authors used a mathematical optimization model to optimize vessel scheduling in ports with restricted channel to reduce vessel waiting time, improve vessel transportation efficiency, and ensure transportation safety, while considering constraints such as complex navigation rules of restricted channel and scheduling resources.

Collision Risk Index Calculation Based on an Improved Ship Domain Model
Weifeng Li,Lufeng Zhong,Yan Xu,Guoyou Shi +3 more
TL;DR: In this article , the authors constructed an elliptical, dynamic ship domain that changes with ship speed and maneuverability parameters to overcome subjective human factors, and the concept of the ship domain proximity factor is introduced to improve the ship collision risk model based on DCPA and TCPA, and a risk calculation function model that considers the safety of ship navigation is constructed.

Weifeng Li,Lufeng Zhong,Yaochen Liu,Guoyou Shi +3 more
TL;DR: In this paper , a ship intrusion collision risk (SICR) model is proposed to reduce the influence of human factors on the risk assessment of ship collisions by automating the decision-making process as much as possible.
