摘要
目前嵌入式软件系统在各类装备中大量运用,软件与硬件平台的结合也越来越紧密,工作过程中一旦出现失效,可能导致严重后果。论文采用故障树分析方法,对嵌入式平台的靶标回收系统的可靠性进行测试分析,建立故障树模型,根据计算故障树的最小割集、径集和基本事件的重要度,帮助软件测试人员快速判断影响系统可靠性的关键事件和关键状态,分析导致系统失效的潜在故障发生路径,对系统的可靠性验证和测试用例设计提供有效指导,提高软件测试的效率。
Embedded software systems are widely used in equipment and the combination of software and hardware platforms is becoming more and more compact. Mistakes in work may lead to serious consequences. This paper uses the fault tree analysis method to test and analyze the reliability of the target recovery system of the embedded platform,establish a fault tree model,and help software testers quickly by calculating the importance of the minimum cut set,path set,and basic events of the fault tree. Identify critical events and critical conditions that affect system reliability,analyze potential failure paths that can lead to system failure,provide effective guidance on system reliability verification and test case design,and improve the efficiency of software testing.
