Abstract

An evolutionary method of ship's anti-collision trajectory planning: new experiments R. Kaminski and R. Smierzchalski Gdynia Maritime Academy, ul Morska 83, Gdynia, Poland, Abstract In a collision situation at sea, the decision support system should help the operator to choose a proper manoeuvre in a given navigational situation, teach him good habits, and enhance his general intuition on how to behave in similar situations in the future. An accepted approach here is the use of a multiple criterion decision problem based system. A new version of the oEP/N-H- (Evolutionary Planner /Navigator) algorithm equipped with an on - line mode has been used, as a major component of such a system, for computing the near optimum trajectory of a ship in a given environment. The introduction of the time parameter, moving constrains representing approaching ships, and the on- line mode are the main distinctions of the newly introduced system. The paper presents selected results in the
