PROBLEM TO BE SOLVED: To provide an underwater sailing body coping method recommendation system for more easily and accurately recommending a coping method for preventing an underwater sailing body approaching a hull from colliding with the hull than a conventional method.SOLUTION: A hull motion simulation section 1 simulates a hull motion, a hull sensor simulation section 2 simulates the presence or absence of detection of an underwater sailing body, an underwater sailing body motion simulation section 3 simulates the motion of the underwater sailing body, an underwater sailing body sensor simulation section 4 simulates the presence or absence of detection of a hull, and a countermeasure performance simulation section 5 simulates the presence or absence of induction of the underwater sailing body in relation to dropping of the countermeasure. On the basis of each result of the simulations, an underwater sailing body coping rule preparation section 6 prepares rules constituted of combinations of an avoidance course of the hull, avoidance speed of the hull, the kinds of countermeasures and details of the countermeasures in a fuzzy inference in the form of a membership function and preserves the rules. An underwater sailing body coping method evaluation section 7 evaluates safety of each rule on the present condition. An underwater sailing body coping method extraction section 8 extracts the safest rule from each rule and recommends the rule as a coping method. |
