What is it about?
This research article formulates a mathematical model of the matrix game of the safe ship control process containing: state variables and control, collision risk definition and the form of a collision risk matrix. Multi-criteria optimization of the matrix game was introduced, leading to non-cooperative and cooperative game control algorithms and non-game control. Simulation safe trajectories of own ship for various types of control were compared to the example of the real situation at sea.

Why is it important?
The use of a matrix game with collision-risk for the synthesis of algorithms for computer-aided navigating maneuvering decision makes it possible to take into account the degree of indeterminacy of the navigational situation caused by the imperfection of the law of the sea route and the subjectivity of the navigator making the maneuvering decision to avoid a collision.
Perspectives
The multi-criteria approach to the task of optimizing the safe control of the ship's movement allows taking into account of both the non-co-operative and co-operative game control and the control of the non-target ships.
