Danik O. Models and methods of analysis and synthesis of navigation systems and vessel traffic control based on a priori estimates of technical efficiency

In the paper, an actual scientific task was formulated and solved for the improvement of existing and development of new models and methods for analysis and synthesis of the navigation system and vessel traffic control on the basis of a priori estimates of the technical efficiency of component subsystems. For the first time a model has been developed for determining the effectiveness of the task of navigating and controlling the motion of a ship of non-emergency events, which differs from similar models by representing efficiency as a function of indicators of the efficiency of component subsystems. Application of the model allows to solve the problem of analysis and synthesis of the structure of the navigation system and control of the movement of the vessel in modern conditions. The model of the effectiveness of the navigational complex and the system of traffic control of the accident-damping vessel is improved, which differs from the existing ones taking into account the a priori technical and operational characteristics of the components of the subsystems. Application of the model allows to solve the problem of forming the algorithm of the analysis of the navigation system and control the movement of the vessel in regular and non-standard operating conditions. The method of structural synthesis of the system of navigation and control of the motion of a vessel of non-emergency events is improved, which, unlike the existing one, uses an intellectualized approach for determining the concession between efficiency and cost using parametric models of fuzzy expert conclusions based on neural networks. Application of the method allows to reduce the cost of up to 15% in comparison with variants having the same performance indicators, as well as increase the probability of carrying out a trouble-free shipping at 10-12% at the condition of the constant value of the cost of the system variant, when solving the problems of synthesis of the structure of the navigation system and control of the movement of the vessel.
