On the evaluation of ship maneuvering for collision avoidance by using OZT
2011 IEEE International Conference on Systems, Man, and Cybernetics, 2011Training facilities have recently introduced practical training that involves maneuvering simulators. The simulator helps the trainees realize so-called “Seamanship” which cannot be obtained only by the classroom lectures. However, it is very difficult to judge the trainees' skills through their maneuvering on the simulator. Therefore, in this study it

The Design of a Fuzzy-Neural Network for Ship Collision Avoidance
2006A fuzzy-neural network for ship collision avoidance where ships are in sight of one another is proposed in this article. There are three subsets: the subset of classifying ship encounter situations and collision avoidance actions, the subset of calculating the membership functions of speed ratio, and the subset of inferring alteration magnitude and ...

Ship Collision Avoidance Timing Based on Subjective Collision Risk
2018 3rd IEEE International Conference on Intelligent Transportation Engineering (ICITE), 2018In order to reduce ship collision and promote the safety of navigation. We investigate the fuzzy relational between various factors and the timing of collision avoidance of ships combined with the collision risk, and a method for determining the timing of ship collision avoidance is proposed.

A Multiagent-Based Simulation System for Ship Collision Avoidance
2007This paper presents a multiagent-based simulation system for the decision-making research of ship collision avoidance. The system has the characteristics of flexible agent, variable topology, isomorphic function structure, distributed knowledge storage, and integrated control method. The architecture is proposed with four kinds of agent models, that is

Collision Avoidance among Multiple Ship Agents
ICCTP 2009, 2009According to the characters of marine navigation, this paper extends the concept of the velocity obstacle and develops a reactive approach to collision avoidance among multiple ship agents. By selecting a reasonable velocity within free parts of its maneuvering space that aren’t covered by the union of velocity obstacles of all other ship agents, a ...

Estimating ship collision avoidance probabilities
2004Mathematical approaches and tools used to predict collision frequencies of ships on a passage typically divide prediction into two separate likelihood (probability) terms. The first term represents the frequency of ship encounters with obstacles, either other ships or fixed structures, where the encounters lead to collision if no evasive action is ...

A differential game approach to collision avoidance of ships
2005A differential game method has been developed which divides the state-space into two regions. In one region ship P2 can always cause a collision, in the other region ship P1 can prevent a collision, provided it uses an appropriate strategy. In a future publication slightly different sets of ships will be considered such as to get a feeling for the ...
