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 (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 ...

Fault Tree Analysis is a top-down, deductive method of failure analysis that starts with a defined undesirable event (the “top event”) and maps all potential causes leading to it. By logically organizing these causes, professionals can evaluate …

A fault tree analysis or FTA refers to a systematic approach that involves determining an event’s primary cause using a diagram. Typically, the event is a failure of a process, system, product, or some other issue. It makes assessing risk easier for …

2024年4月23日 · The steps to construct a Fault Tree are as follows: 1. Identify the undesired event. This event is placed at the root (top) of the tree and is typically a system level failure. 2. Determine the immediate causes. These are placed below the root, branching out like the limbs of a tree. 3. Decipher the contributing factors.

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 …

Fault Tree Analysis (FTA) is a step-by-step process that helps identify the root causes of a system failure by systematically breaking down contributing factors. This method uses logical symbols and gates to map out potential events that lead to a defined “top event.”

FTA is a method used to analyze the potential for system or machine failure by graphically and mathematically representing the system itself. It is a top-down approach that delineates how a failure moves through a system. It creates a graphical model of how component failures lead to system-wide failures.

2025年1月23日 · Fault Tree Analysis (FTA) is a top-down, systematic method for identifying potential causes of system failures. Learn how FTA diagrams map failure pathways, diagram structures, improve risk management, and ensure system reliability.

The FTA process encompasses three steps: Development of a fault tree diagram. Identification of failure events, triggering events, and contributing factors based on the diagram.
