可靠性测试是安全关键系统可靠性评估的重要手段。论文结合在某电信系统的工程实践，介绍一种基于故障剖面的可靠性测试和评估的方法：通过逆向工程从已有的安全关键系统的失效事件中分析提取出故障概率数据，结合故障注入测试对系统的可靠性进行评估。该方法直接从故障入手，不受缺乏缺陷引发故障概率数据问题的困扰，并通过故障模式的双层模型明确测试范围，简化了评估过程。
可靠性測試是安全關鍵繫統可靠性評估的重要手段。論文結閤在某電信繫統的工程實踐，介紹一種基于故障剖麵的可靠性測試和評估的方法：通過逆嚮工程從已有的安全關鍵繫統的失效事件中分析提取齣故障概率數據，結閤故障註入測試對繫統的可靠性進行評估。該方法直接從故障入手，不受缺乏缺陷引髮故障概率數據問題的睏擾，併通過故障模式的雙層模型明確測試範圍，簡化瞭評估過程。

Reliability testing is one of import ways for evaluating the reliability of safety‐critical system .According to the engineering practice in a telecommunication system ,a new reliability testing and evaluation approach is proposed based on the fault profile .The fault probability is extracted from the failure events of the existing safety‐critical system by reverse en‐gineering .The system reliability is evaluated via injecting faults during reliability testing .The approach directly starts from the fault ,without being troubled by missing fault probability data .By the two layered fault model of fault patterns ,our ap‐proach can determine the scope of reliability testing and simplify the evaluation process .
