Abstract

In this paper, safe ship trajectory in collision situation is presented as multistage decision-making in a fuzzy environment*. The model of process takes under consideration the Collision Avoidance Regulations, the manoeuvrability parameters of ship and the navigator's subjective assessment in making a decision. The time of taking the observation of an object and the time of collision avoidance manoeuvre are determined on the membership function of the fuzzy set of a collision risk. The algorithm has been worked out with regard to an on-line control status. A situations of a multiship encounter have also been simulated. 1 Introduction The problem of collision avoidance has become an urgent issue, therefore it is necessary to
