Abstract

Evaluating the risk of collision quantitatively plays a key role in developing the expert system of navigation and collision avoidance. This study analysed the existing methods of appraising the collision risk, examined the problem that are intrinsic to them, and developed a new approach to its evaluation by using the sech function as an alternative to them. This paper applied the new method in appraising the collision risk and suggested how to decide the safe range of ownship's action.

충돌위험도의 정량적인 평가는 항해 충돌방지 전문가 시스템 개발에 있어서 중요한 역할을 한다. 이 연구에서는 기존의 충돌위험도 평가 방법을 분석하여 문제점을 비교 검토하였으며, 그 대안으로 Sech 함수를 이용한 충돌위험도 평가 방법을 새롭게 시도하였다. 이를 충돌위험도 평가에 적용하고 본선의 안전한 행동구간을 결정할 수 있는 방법을 제시하였다.
