Artificial intelligence methods in navigator decision support system

Abstract

The decision system in ship steering at sea should help the navigator to learn and enhance his intuition about a given decision. In the process computer modelling and simulation are preliminaries for decision making. The decision support system is a collection of procedures (data and parameters of the situation at sea, model of own ship, algorithms etc.) necessary to make decision. One of the accepted ways of supporting in solving such problem is a multi-criterion and multi-level decision process. The navigator is supported during controlling the process of generating and evaluating various options of efficient decision in a multi-objective and optimum way. Multi-criterion and multi-level decision problem of safe ship steering has to be based on the criterion of own ship's cost and the safe pass condition for own ship.
