Multi-Ship Collision Avoidance Decision-Making Based on Collision Risk Index

Journal of Marine Science and Engineering, 2020
Most maritime accidents are caused by human errors or failures. Providing early warning and decision support to the officer on watch (OOW) is one of the primary issues to reduce such errors and failures. In this paper, a quantitative real-time multi-ship
