Modeling and simulation of ships transport by using hybrid Petri nets

U ovom diplomskom radu je modeliran i simuliran prometni sustav sa raskrižjima gdje su rute brodova, koje prolaze sustavom, unaprijed određene od strane VTS centra (eng. Vessel Traffic System ) korištenjem petrijevih mreža. Simulacijom je utvrđeno da bi se u raskrižjima mogao naći veliki broj brodova u slučaju kada promet ne bi bio nadziran i kontroliran. Iz tog razloga razvijen je model prometnog sustava koji uključuje kontrolnik koji limitira broj brodova u raskrižjima. Rad kontrolnika verificiran je računalnom simulacijom pomoću programa Visual Object Net ++. KljučneIn this thesis nautical system with intersections is modelled and simulated, where the routes of the vessels, which pass through system are predetermined by the Vessel Traffic System using Petri nets. Simulation showed that there could be a large number of vessels in intersections in case where no control exists.That is the reason why control unit which limits the number of the vessels in intersections is developed. The function of supervisor is verified by using computer simulation program Visual Object Net ++
