IMPROVEMENT OF THE MATHEMATICAL MODEL OF THE NAVIGATION ENVIRONMENT FOR PLANNING A GUARANTEED WIRING LANE AND PLANNING THE OPTIMUM ROUTE OF THE PASSAGE OF VESSELS

Abstract

A systematic planning process ensures the development of a detailed and appropriate transition plan, which allows the shipmaster to respond in advance to critical situations and important areas during the ship's movement. The assessment process consists in collecting, processing and analyzing all information about the navigational situation. This process allows the shipmaster to clearly and accurately identify and delineate all areas where dangerous situations may arise. The navigation situation is characterized by a high intensity of territorial activity (freight and passenger transportation, mining, research, defense activities, fishing, etc.), a multitude of navigational hazards (the bottom has a complex topography, shallow depths, ice, currents, the influence of land) and the variability of hydrometeorological conditions Various geo-information tools are used on the drawbridge to display and analyze the territorial situation. A feature of ship geoinformation systems is their focus on solving a wide range of problems. However, to implement a holistic and systematic approach to the implementation of the concept of e-Navigation. Harmonized collection, integration, exchange, presentation and analysis of navigational information between ship and shore services by electronic means should be carried out. Therefore, it is expedient to consider the possibility of creating an apparatus for formalizing the navigation situation, which allows unambiguous separation of information and mechanisms of its processing in the modeling process. The work improves the mathematical model of the navigation situation for planning the guaranteed routing lane and planning the optimal route for the passage of vessels, the basis of which, unlike the known ones, is the formalism of discrete effective systems with elements of fuzzy logical derivation, which allows to increase the efficiency and accuracy of modeling a complex navigation situation with a large the number of navigational hazards.
