We have proposed modeling methods of mariners' standard behavior for collision avoidance by analyzing mariners' recognition process in a previous study. As a subsequent study, the aim of this study is to build a model of mariners' execution process which is one of six processes in the condition of collision avoidance. In this study, thus, the structure of mariners' information processing on the process of taking avoiding actions is described and the relation between mariners' behavior and necessary factors in the process is analyzed. And then we have built a model of mariners' standard behavior for execution process based on the characteristics of mariners in ship-handling, which are obtained from the international collaborative research on human factors. It is tried to define the contents of execution process based on the standard behavior of mariners for collision avoidance and to formulate information processing of mariners.

최근 국내에서 장대교량의 건설이 증가함에 따라 그에 대한 내진설계의 중요성도 증대되고 있다. 이와같은 여건을 반영하여 새로 개정된 케이블 강교량 설계지침(안)의 내진설계편에서 지진파의 파동전달효과와 지반특성효과를 일부 반영하였다. 본 연구에서는 국내 설계규정에 따라 사장교(주경간500m)의 다양한(균등입력, 파동전달효과, 파동전달효과+지반특성효과) 지진응답해석을 수행하여 설계적용시 문제점에 대하여 검토해 본 결과 장대교의 파동전달효과는 지지점간 거리가 짧은 경우에도 지반이 연약한 경우 큰 영향을 받는 것으로 나타났다. 한편 지반의 종류에 상관없이 파동전달효과와 함께 지점별로 지반특성을 고려한 해석이 그렇지 않은 해석결과보다 큰 값이 산출되었다. 따라서 장대교의 지진응답해석시 파동전달효과 및 지반특성효과의 적용에 대한 세심한 고려가 필요한 것으로 판단된다.

We've investigated the characteristics on mariner's behavior in the collision situation through a full-mission ship handling simulator and considered that it's necessary to model the standard avoiding behavior of mariners in order to apply the obtained results more widely and effectively. Thus we described the contents of standard avoiding behavior taken by mariners in the collision situation and established the concept of the standard model based on human factors for collision avoidance in a previous study. As a following study, this paper is to propose the method of modeling on mariners' standard behavior for collision avoidance by analyzing the contents of mariner's information processing and the related factors using regression analysis. As a result, we confirmed the influence of relating factors to avoiding behavior in mariner's deciding decisions and proposed the modeling method of mariners' standard behavior for collision avoidance with a example of recognition model.

Human factors have been considered the primary reason of marine accidents. Especially, the collision between vessels is mostly mused by human behavior. However, there have not been many researches to clarify the reason of marine accidents mused by human factors quantitatively. In order to understand human factors and to enhance safe navigation systematically, using a full mission ship-handling simulator, we've investigated the characteristics of avoiding behavior taken by mariners. Further in order to apply the characteristics more widely and effectively, it's necessary to formulate the standard behavior for ship-handling in the condition of collision avoidance. Is this study, therefore, we intended to propose the concept to model the mariner's standard behavior on the handling of collision avoidance as the first step. As a result, we confirmed the contents of information processing in ship-handling that mariner's generally taking to avoid collision.
