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 ...

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 (FTA) is a powerful method for identifying potential system failures and improving risk management strategies. This guide simplifies the concept, offering insights into its structure, applications, and best practices.

Fault Tree Analysis (FTA) is a graphical tool used to explore the causes of system-level failures. It uses Boolean logic to combine a series of lower-level events. It is basically a top-down approach to identify the component-level failures (basic events) …

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.

2024年9月27日 · Learn how to use fault tree analysis (FTA) to identify and understand the cause of a potential issue before equipment breakdowns occur.

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.

2024年11月29日 · 故障树分析法（Fault Tree Analysis，FTA）是一种用于系统可靠性和安全性分析的重要技术。 以下是详细介绍： 一、基本概念. 故障树是一种特殊的倒立树状逻辑 因果关系 图，它从系统可能发生的最不希望出现的故障事件（顶事件）开始，逐步向下追溯所有可能导致顶事件发生的原因事件，包括 硬件 故障、软件错误、人为失误以及环境因素等。 这些原因事件通过逻辑门（如与门、或门等）连接起来，形成一个完整的故障逻辑结构。 二、故障树的构成要素. …

2024年11月27日 · Fault Tree Analysis (FTA) is an essential tool for understanding system reliability, identifying potential failures, and mitigating risks. By utilizing fault tree analysis symbols effectively, you can transform complex systems into clear, actionable diagrams that provide valuable insights into potential failure modes and their causes.

This quick subject guide provides an overview of the basic concepts in fault tree analysis (FTA, system analysis) as it applies to system reliability, and offers a directory of some other resources on the subject.
