A multicriteria outranking approach for ship collision risk assessment
Reliability Engineering & System Safety, 2021Abstract The paper presents a judgmental expert-based process to assess the ship collision risk using the ELECTRE Tri-nC multiple criteria outranking method. The approach first establishes a set of criteria deemed important by navigation experts, all of them experienced nautical officers, to assess the collision risk between two ships in open waters.

Collision risk assessment for ships
Journal of Marine Science and Technology, 2010Efficient maritime navigation through dynamic obstructions at close range is still a serious issue faced by mariners. There have been studies focusing on collision risk assessment in the past, but the majority were based on the first person perspective, with area-based ship domain concepts that are defined around either the ownship or the obstacle ...

Ship Collision Avoidance Utilizing the Cross-Entropy Method for Collision Risk Assessment
IEEE Transactions on Intelligent Transportation Systems, 2022In this article, a new approach for ship-ship collision probability estimation based on the Cross-Entropy (CE) method is introduced, which can be treated as an adaptive importance sampler. It has the advantage of attaining low variance estimates of small collision probabilities, which will most often be the case in realistic scenarios.

An Airspace Collision Risk Simulator for Safety Assessment
2019 Winter Simulation Conference (WSC), 2019Modelling the spatio-temporal dynamics and evolution of collision risk in an airspace is critical for multiple purposes. First, the model could be used to diagnose the critical points where the level of risk has escalated due to particular airspace configurations and/or events.

Collision theory in electric shock risk assessment
2014 AEIT Annual Conference - From Research to Industry: The Need for a More Effective Technology Transfer (AEIT), 2014The main protection against electric shock is the “active” measure based on preventing the persistence of the electrical hazards limiting the time duration of the risk exposure to the electric contact. For the electrical risk assessment, the analysis of the risk exposure is treated by an innovative approach in analogy with collisions problems ...

Exploring an Alternative Approach to the Assessment of Collision Risk
Journal of Guidance, Control, and Dynamics, 2023This paper explores the construction of a collision assessment method exploiting an alternative to probability theory for the representation and quantification of uncertainty of the states for two anthropogenic space objects (ASOs). Propagated uncertainty in the position and velocity of an ASO depends on, for example, seemingly random measurement ...

A selecting method in collision risk assessment
2010 3rd International Symposium on Systems and Control in Aeronautics and Astronautics, 2010With the increase of space debris, the technology of spacecraft collision avoidance has become more and more important. In this paper, an analytical method of selecting objects is investigated based on mean elements, which is free from the restriction of the spacecraft launch time and the instantaneous position. If only the launch orbit of a spacecraft

Journal of Navigation, 2005
Edmund Hadnett writing in his article AIS at the Front Line in the May 2005 issue of the Journal, attributes to me the argument that ‘the automatic radar plotting aid (ARPA) should remain the principal means of assessing a risk of collision’. ARPA has never been the principal means of assessing a risk of collision and I have never argued that it has ...

Risk assessment of collisions of an autonomous passenger ferry
Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 2021Autonomous transportation is an increasingly popular concept and is gradually becoming a reality. This transformation also changes the way people travel. For example, the autonomous ferry is an emerging alternative for residents living in coastal areas. To evaluate the safety of an autonomous ferry, a thorough safety review is necessary.

Development of a collision risk assessment tool
Advances in Space Research, 2004Abstract GMV is currently developing a software tool for ESOC, ESA's European Space Operations Centre, which shall forecast close conjunctions of selected spacecraft with over 8000 objects included in the US Satellite Catalog. The Collision Risk Assessment Tool (CRASS), shall generate collision risk estimates and collision warnings based on collision
