基于安全会遇距离模型的智能船舶航行行为可靠性评估

Reliability assessment of intelligent ship navigation behavior based on safe encounter distance mode

为提高智能船舶的可靠性和航行安全性,提出了一种基于安全会遇距离模型的智能船舶航行行为可靠性评估方法。文章构建智能船舶航行行为可靠性评估指标体系,并运用船舶安全会遇距离模型,建立智能船舶在两船互见会遇场景中的航行行为故障判断流程,研究在不同会遇场景中智能船舶航行行为可靠性指标值并进行对比分析。研究结果表明,该可靠性评估方法能够对处于不同会遇场景中的智能船舶航行行为进行评估,所建立的可靠性评估体系是可行且有效的,能为智能船舶的可靠性设计和评估提供新的思路。

In order to improve the reliability and navigation safety of intelligent ships,a reliability evaluation method of intelligent ship navigation behavior based on safety encounter distance model is proposed.This paper constructs the reliability evaluation index system of intelligent ship navigation behavior,and uses the ship safety encounter distance model to establish the fault judgment process of intelligent ship navigation behavior in the scene of mutual meeting between two ships.The reliability index values of intelligent ship navigation behavior in different scenarios are studied and compared.The results show that the reliability evaluation method can evaluate the navigation behavior of intelligent ships in different scenarios,and the reliability evaluation system is feasible and effective.It can provide new ideas for reliability design and evaluation of intelligent ships.
