TLDR
In this article, several fuzzy sets are introduced to simulate the mariners' collision avoidance decision making behavior and their psychology, and simulation models are established on an action to avoid collision in head-on, creasing and overtaking situations.Abstract:
Decision making in collision avoidance is one of the major problems in ship manoeuvring. The basis of ships collision avoidance decision making at sea is the Collision Regulations which prescribe that two encountered vessels should pass at a safe distance. In this paper, several fuzzy sets are introduced to simulate the mariners' collision avoidance decision making behaviour and their psychology. Simulation models are established on an action to avoid collision in head-on, creasing and overtaking situations, in restricted waters in traffic separation schemes, in restricted visibility and with obstacles. This work lays a theoretical foundation on for the development of marine traffic simulation and automatic collision avoidance systems. Finally, an investigation on the mariners' behaviour is reviewed, and a simulation conducted to compare with other studies. >read more

A study on the collision avoidance of a ship using neural networks and fuzzy logic
TL;DR: This paper proposes calculation method of the collision risk by using neural network, and MLP (Multilayer Perceptron) neural network to the collision avoidance system is applied to make up for fuzzy logic.

An Empirically-Calibrated Ship Domain as a Safety Criterion for Navigation in Confined Waters
Yueying Wang,Hoong Chor Chin +1 more
TL;DR: In this paper, a free-form ship domain has been developed empirically for navigation in confined waters, where two individual domains of an asymmetrical polygonal shape have been assumed around the own ship and target ship, and the size of the ship domains is dynamically enlarged with increased ship speeds.

Automatic collision avoidance of ships
Y Xue,Byung Suk Lee,Duanfeng Han +2 more
TL;DR: In this paper, the authors present a new practical method of automatic trajectory planning and collision avoidance based on an artificial potential field and speed vector, which has been shown to be effective in finding safe paths for all ships concerned in complex situations.

Collision risk measure for triggering evasive actions of maritime autonomous surface ships
TL;DR: The collision risk is monotonically increasing when introducing more ships, and ignorance of ship maneuverability results in an underestimation of collision risk.

Solutions to the Failures and Limitations of Mamdani Fuzzy Inference in Ship Navigation
TL;DR: A decision-making process for ship navigation is analyzed, input and output fuzzy membership functions are derived, an if-then-rule-based fuzzy inference system is formulates, and simulation results that support recovery from rule inference failures in several contradictory decision boundary conditions are presented.

Marine Traffic Behaviour in Restricted Waters
TL;DR: In this paper, the authors present the development and analysis of the ship domain in restricted waters and illustrate some of its uses in a buoyed channel, where the analysis of marine casualties raises the question of how casualties occur and may indicate the circumstances most likely to lead to a casualty.
Journal ArticleDOI
Comments on ship domains
TL;DR: Fujii et al. as discussed by the authors used a new branch of social psychology to analyse the factors which affect the ship domain, and pointed out that the basis of producing ship domains is in the field of Proxemics.

Modelling the decision process in computer simulation of ship navigation
TL;DR: The Collision Regulations are designed to assist navigators to avoid collisions at sea as mentioned in this paper, and because of their qualitative nature it has been proposed that the Regulations should be supplemented by quantitative references to give practical meaning to concepts like safe passing distance, early action, etc.

Risk assessment of ship/platform collision
TL;DR: In this paper, a theoretical study on the assessment of risk of collision between ships and offshore installations is performed, in which the causes of collision and the models of evaluating the risk collision are reviewed, and some suggestions on reducing such a risk are proposed.
