Palamarchuk I. Models, methods and information technology of decision taking support on the control of the vessel movement during maneuvering

The work is devoted to the development of models, methods and information technology of decision taking support on the control of the vessel movement during maneuvering. The object of research is process of controlling the movement of the vessels during maneuvering. The purpose of research is to increase the safety of modern shipping by developing new models and methods of vessels movement control during maneuvering for decision support systems in navigation. Research methods used: methods of mathematical modeling to determine the predicted trajectory of vessels, artificial intelligence methods and elements of the theory of expert systems to develop technology for choosing solutions of vessels movement control, methods of scenario analysis to predict the development of navigational situations happened, situational analysis methods for determining the sequence of actions of the navigator in preventing collisions. It is established that at the moment there is an urgent need to create modern DSS for vessels movement control, which take into account the peculiarities of human interaction with technical means of navigation and ensure its decision taking in difficult navigational conditions and critical situations, as well as able to effectively solve issues, related to the processes of forming vessels controls decisions and reducing the impact of the "human factor" on this process. For the first time, an information model of real-time vessel movement control has been developed, which takes into account the available experience of the navigator, navigation information and restrictions on vessels traffic in the current situation and reduces the risk of erroneous actions in vessel movement control. For the first time a method of vessel maneuvering control was developed on the basis of situational analysis of the divergence process and complex criteria for assessing the level of danger, which allows to determine the danger of navigation situation in real time and prevent possible collisions. The model of the navigator and methods of its formation in the process of interaction with technical means of vessel control are developed, which allows reducing the influence of human factor on the processes of vessel movement control due to more effective interaction of the navigator with technical means of navigation. The information technology of support decision taking of the navigator on vessels movement control at maneuvering is developed, that’s provides reduction of risks of occurrence of emergency situations in navigation. The structure of the navigator DSS has been improved, which allows to comprehensively solving the problems of divergence and maneuvering of vessels, taking into account the requirements of COLREG-72 and maneuvering characteristics of the vessel. The developed prototype of DSS of the navigator on vessels movement control process which application provides increasing of quality of training of seafarers in the educational institutions and the training centers. Field of use - in the educational process in maritime education institutions, marine training centers, crewing companies and in navigation on ships of Ukrainian and foreign ship-owners.
