Abstract

Behavioral errors of the seafarers are one of the major causes of collisions and are usually corrected through education and training. To correct this behavioral error, the structure in which the behavioral error occurs needs to be identified and analyzed. For this purpose, behavior observation data were obtained through ship maneuvering simulation for collision encounters. The 9-state behavior classification frame proposed by Reason was used for the behavior observation and 50 university students were involved in the experiment. Behavioral analysis used the behavioral model of collision avoidance success and failure, which was developed from the 9-state Left-to-Right Hidden Markov modeling technique. As a result of the experiment, the difference between behaviors of success and failure of collision avoidance was clearly identified, and the linkage between 9-state behaviors, required to prevent collision, was derived.

해기사의 행동오류는 충돌사고의 주요한 원인 중 하나이고, 교육과 훈련을 통하여 보정이 가능한 것으로 알려져 있다. 이러한 행동오류의 보정을 위해서는 행동오류가 발생되는 구조의 식별이 필요하다. 이를 위하여, 충돌조우상황에 대한 선박조종 시뮬레이션을 통해서 행동관측 데이터를 획득하고, 행동관측에는 Reason이 제안한 9-상태 행동오류 분류 프레임을 이용하였으며, 실험에는 50명의 대학생들이 참가하였다. 행동분석에는 충돌회피의 성공과 실패로 구분한 행동 모델을 이용하였는데, 이 모델은 9-상태의 Left-to-Right 구조를 갖는 은닉 마르코프 모델링 기법을 이용하여 개발하였다. 실험결과, 충돌회피의 성공과 실패에 대한 행동들 사이의 차이가 명확하게 식별되었고, 충돌예방에 필요한 9-상태 행동들 사이의 연계관계가 도출되었다.
