2023年4月30日 · 故障树分析(Fault Tree Analysis, FTA)是以一个不希望发生的产品故障事件(用于预防性的安全分析)或者已经发生的失效事件(用于故障排查)作为顶事件作为分析的对象,通过由上向下的严格按层次的故障因果逻辑分析,逐层找出故障事件的必要而充分的直接原因 ...
Fault tree analysis - Wikipedia
Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident ...

什么是故障树分析?| IBM
故障树分析 (FTA) 是一种 根本原因分析 方法,可在设备发生故障之前发现并分析资产问题的根本原因。 故障树分析是一种由上往下的演绎式分析法,用于确定复杂系统中特定意外事件的成因。 它将故障的根本原因分解为多个促成因素,然后通过一种称为“故障树”的图形模型来表示,协助管理人员和工程师找出潜在的故障模式以及每种故障模式的发生概率,以便进行安全性和可靠性分析。 FTA 最初于 20 世纪 60 年代初由贝尔实验室开发用于帮助美国空军了解民兵导弹系统的潜 …
What is Fault Tree Analysis - Visure Solutions
Fault Tree Analysis (FTA) is an essential technique for identifying risks, enhancing system reliability, and ensuring safety in complex systems. By breaking down failures into their root causes, FTA helps industries such as aerospace, healthcare, manufacturing, and energy assess risk, prevent catastrophic failures, and improve system designs.
FTA has been refined further in recent years and has since become a widely used analysis method for assessing the safety and reliability of large and complex systems from the technical viewpoint. The ISO 26262 introduced in automotive engineering in …
