Abstract: This paper compares the difference between hardware and software, which may cause the difficultness to apply failure modes and effects analysis(FMEA) to software. After reviewing software FMEA (SFMEA) techniques at first, it puts forward an integrated hardware/software FMEA techniques. The experience shows that this integrated FMEA techniques is suitable for embedded real-time control system, and can improve the safety and reliability of the system.

摘要： 比照硬件失效模式影响分析FMEA技术(FMEA)，分析了影响软件FMEA的因素，在对软件FMEA技术进行简要综述的同时，提出了一种适合于计算机实时控制系统的软硬件综合FMEA方法。工程应用表明，这种软硬件综合FMEA方法可用于计算机实时控制系统的设计过程，对提高系统的可靠性、安全性具有一定作用。
