Study on the forecasting of two cold surge events from the viewpoint of maritime transport

Meteorological Applications, Volume 32, Issue 2, March/April 2025.
The WRF model is more accurate than relative humidity in simulating temperature and dew point temperature, which is more important for judging the occurrence of fog. The YSU scheme is an excellent PBL scheme for sea fog forecasting during the cold surge in the Bohai Bay region.

DSSA+: Distributed Collision Avoidance Algorithm in an Environment where Both Course and Speed Changes are Allowed [PDF]

TransNav, 2019
Distributed Stochastic Search Algorithm (DSSA) is one of state-of-the-art distributed algorithms for the ship collision avoidance problem. In DSSA, whenever a ship encounters with any number of other ships (neighboring ships), she will select her course ...

Nash Bargaining Strategy in Autonomous Decision Making for Multi‐Ship Collision Avoidance Based on Route Exchange

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
The concept of closest spatio‐temporal distance (CSTD) is introduced to more accurately assess collision risk between ships. By adopting route exchange, the multi‐ship collision avoidance problem is regarded as a multi‐stage static cooperative game under conditions of complete information.
