Knowledge Base in the Interpretation Process of the Collision Regulations at Sea

The article presents the problem of transforming knowledge contained in the provisions of the International Regulations for Preventing Collisions at Sea, and the so called good seamanship in computer applications. Some methods of knowledge representation in decision support in avoidance of collision situa-tions are compared and examined. Acquisition, representation and sharing of knowledge are taken into con-sideration from the viewpoint of supplementing the knowledge database and computational complexity.
