Safety of Navigation Based on Game Theory-computer Support Algorithms of Navigator Decisions Avoiding Accidents at Sea

Józef Lisowski

  In this paper each approximated model of the dynamic game has been assigned appropriate methods of a safe steering method to support the navigators decision in a collision situation in the form of the game trajectory algorithms. The Positional Game (POSGAME) and Risk Game (RISKGAME) manoeuvring control algorithms have been designed in the MATLAB 6.5 language. The considerations have been illustrated with an example of a computer simulation the POSGAME and RISKGAME algorithms to determine the safe ship s trajectory in situation of passing a many of the objects encountered, recorded on the ship s radar screen in real navigational situation at sea. Finally, the sensitivity of ship game control to inaccurate data from the ARPA anti-collision radar system and to variation in ship dynamics is presented.……
