Yanchetskyy O. Improvement of methods of warning of collision of vessels by the account of efficiency of their maneuver of divergence

The basic stages of process of decision-making on warning of collisions of vessels are expounded in work. It is shown that four stages are substantial. For comparison of the analytical collision avoidance systems vessels the offered procedure of estimation of their efficiency which is determined by probability of safe completion of process of divergence. Estimation of probability of degree of danger is offered rapprochement of vessels, for the calculation of which analytical expression of closeness of probability distribution of error of distance of the shortest rapprochement is got. The method of estimation of probability of correct determination of type of cooperation of vessels and choice of optimum strategy of divergence is developed. Shown advantage of external process control of divergence of vessels for lack of necessity of coordination of their cooperation. Procedure of determination of group of interactive vessels for determination of compatible strategy of divergence with the purpose of indemnification of situation indignation is offered. An algorithm and procedure of determination of strategy of divergence of group of vessels which are dangerously drawn together is developed in work. For the decision the set problem the method of scanning of planes of pair courses of vessels is offered. For the situation of dangerous rapprochement of a few vessels by the got algorithm the imitation program of determination of optimum strategy of divergence was developed. Keywords: safety of navigation, warning of collisions of vessels, external management, strategy of divergence of group of vessels, imitation design.
