摘　　要：针对舰船航行功能体系较为复杂的特点,引入故障树中概率重要度的概念对舰船航行功能体系进行功能易损性分析。建立舰船航行功能毁伤树模型,并对其进行定性和定量分析,将底事件的概率重要度作为底事件功能易损性的评价指标。分析结果表明该方法对舰船功能易损性分析具有一定的参考意义,是解决该问题的一种途径。The concept of probability importance in fault tree is introduced to analyze the functional vulnerability of ship navigation functional system.The damage tree model of ship navigation function is established and analyzed qualitatively and quantitatively.The probability importance of bottom event is taken as the evaluation index of the vulnerability of bottom event function.The analysis results show that this method has a certain reference significance to the ship functional vulnerability analysis,and is a way to solve the problem.
