| 摘 要： | 对某助推伺服控制软件开展失效模式影响分析(SystemFailureModeandEffectsAnalysis,SFMEA) 和故障树分析(SoftwareFailureTreeAnalysis,SFTA)。SFMEA 是一种自下而上的分析方法,用以辨识出一系列可能的软件潜在故障模式,并评估其对系统工作的危害性。SFTA 是一种自上而下的分析方法,其目标是识别出基本事件(底事件),而基本事件可导致系统产生其所不希望发生的顶事件。应用SFMEA和SFTA的主要目的是提高软件和系统的安全性及可靠性。

| Abstract: | This paper particularly applies SFMEA and SFTA in a real-time hydraulic servo control software. SFMEA is a bottom-up analysis technique to identify the consequences of possible software failure modes and to evaluate its effects on the operation of the system. SFTA is a top-down analysis technique to identify the contributing elements that could cause the system level undesired events. The main purpose of the analysis above is to improve the safety and reliability of the system. |
