METHOD AND SYSTEM FOR CONTROL OF VESSEL LOCATION BY MEANS OF FUZZY LOGIC Russian patent published in 2019 - IPC B63H25/00 

FIELD: navigation systems.

SUBSTANCE: control of the vessel’s location includes obtaining navigation parameters entering the input information block, and then into the information processing block, using fuzzy logic: in the created matrix, each cell is assigned X and Y coordinates, after which it is subjected to fuzzy clustering to highlight areas with increased danger. Location of the vessel is determined by cumulative accounting of navigation information from various sources using fuzzy numbers, as well as the degree of danger of following the vessel along the lines obtained in the block generating preliminary lines in a clustered environment. In the blocks for finding the coordinates X and Y, the coordinates of the cells through which the preliminary laying lines pass are determined. Output data is entered into the unit for checking pre-laying lines in a clustered environment, receiving a current hazard rating and the magnitude of the hazard in a graphical form as you follow the route. It is possible to comprehensively evaluate the safety of the route, safety in the current navigation environment and comprehensively evaluate data from various sources.

EFFECT: significantly increases the security of the wiring of the vessel.
