| 摘要: |
| 实际中普遍存在的有显著渐近失效行为的系统，难以用经典故障树加以分析，于是，以“模糊事件的普通概率”这一理论为基础，建立了Profust故障树模型，并进行了部分定量分析，该模型的最大特点是综合运用了可以得到的关于系统运行的可能性信息和概率信息。 |
| 关键词: Profust故障树 渐近失效 模糊事件的普通概率 |

| Abstract: |
| In system performances, the phenomenon of gradual failure can't be analyzed by traditional (Probist) fault tree. To solve this problem, the model of Profust fault tree and its partial quantity analysis is given according to the theory of “probability of fuzzy events”. The prominent characteristic of this model is that it employs both the available possibility and probability information of the given system. |
| Keywords: Profust fault tree gradual failure probability of fuzzy event |
