Tymoschyk O. Trusted Situation Method for Safe Collision of Ships and Safety of Navigation

The dissertation is devoted to the solution of the actual scientific problem of developing a method for improving the safety of navigation and navigation of sea and river vessels in difficult navigational conditions by increasing the efficiency and soundness of the decision by the skipper in the event of a dangerous situation of convergence (collision) was solved. The scientific novelty of the study is that: an improved method for presenting and processing knowledge about the problems of identifying dangerous situations of proximity (collision) in the area of responsibility of the skipper, which differs from the known formalized description of the process of recognizing situations in the water area of a ship based on fuzzy logic and heterogeneous functional networks , which allow to take into account the uncertainty and inconsistency of processes in the automation of the process of recognizing situations. An improved method for assessing the degree of danger taking into account the transitional conditions in which the vessel is in dangerous situations, which differs from the known ones by the development of a comprehensive assessment of the dangerous situation of approach (collision) using declarative knowledge and the existing uncertainty of the time of use of resources. An improved method for synthesizing a solution option to avoid a dangerous approach (collision) situation, which differs from the known ones by using a systematic approach to describing and evaluating the effectiveness of a maneuver to prevent dangerous situations. Presentation of the vessel as a system allows you to take into account the influence of automation on the effectiveness of solving tasks assigned to the skipper in the elimination of dangerous situations.
