Abstract

When VTSOs (Vessel Traffic Service Operator) determine the degree of collision risk for two vessels, they consider comprehensive information about each vessel’s course, speed, DCPA, TCPA, and encountering situation. In this study, we proposed a utility function based on the risk attitudes of VTSOs toward the Risk Index (RI). The RI was calculated using the risk of encounter, the risk of approach, and the risk of time for two vessels in order to predict each ship’s collision risk from the VTS viewpoint. We obtained each coefficient of the RI and the risk attitude through a survey of collision risks among VTSOs of Korea. In order to verify whether the proposed utility is reasonable, we validated by applying the degree of collision risk to some historical cases of accidents in Busan port along with the Ship of ES value() of ES(Environmental Stress) model.
通过分析船舶交通服务经营人的风险态度研究船舶碰撞风险程度
船舶交通服务操作员在确定两艘船只的碰撞风险程度时,会综合考虑每艘船只的航向、速度、DCPA、TCPA和相遇情况等信息。在这项研究中,我们提出了一个基于职业经理人对风险指数(RI)的风险态度的效用函数。为了从VTS的角度预测每艘船的碰撞风险,使用相遇风险、接近风险和两艘船的时间风险来计算RI。通过对韩国vtso碰撞风险的调查,我们得到了RI的各个系数和风险态度。为了验证所提出的效用是否合理,我们通过将碰撞风险程度应用于釜山港的一些历史事故案例以及ES(环境压力)模型的ES值()船舶进行验证。
