Imitation design of process of divergence of three vessels

The offered work is devoted to verification of correctness of method of choice of parameters of maneuver of divergence of group of vessels by the change of their courses with the use of procedure of forming of regions of impermissible values of courses of every pair of vessels. The computer program which allows generating the initial situation of dangerous rapprochement of group of vessels was developed for this purpose. Then for the generated dangerous situation the computer program determines the maneuver of divergence of vessels by the change of their courses and his imitation design which produces the animation reflection of process of divergence with the conclusion of current distance between vessels and comparison of her with produced – possible distance of rapprochement. As an example the situation of dangerous rapprochement of group consisting of three vessels is considered in work, thus for all vessels there is the danger of collision. The indicator of danger applied in the computer program, and which shows that the all ships are dangerously drawn together, testifies to it, for each of which there is situation indignation. In the program the graphic reflection of regions of dangerous courses of every pair of the drawn together vessels is foreseen and by a scroll bar the input of values of courses of deviation of every pair of vessels is possible. Because situation indignation exists between all vessels, for his indemnification it is necessary to change courses some ships. It was set by the preliminary analysis, that more preferable there is the change of course by the second and third ships, because requires less deviation from a programmatic course. If a third ship will deviate to the right, at the conclusion of course from a dangerous region indignation with the first ship appears by a situation, it is therefore necessary to produce the change of course of ship to the left, although it is attended with large deviation from his programmatic value. Does optimum safe divergence of vessels on distance 1,02 miles take place at deviation of the third ship on 62˚ to the left. The results of imitation design are represented in work, confirmative correctness of the chosen maneuver of divergence, thus the shortest rapprochement on 1,01 miles of the second and first vessels takes place on 568 s the process of divergence.
