１基本概念上一讲我们介绍了可靠性框图，了解了系统（产品）的逻辑关系，进一步的分析我们还要使用故障树分析技术（FTA）和故障模式与后果分析技术（FMEA）。故障树分析（FaultTreeAnalysis）简单地讲就是把产品（系统）最不希望发生的故障作为故障分析的目标，把选定的产品 1 Basic Concepts Previous We introduced the reliability diagram to understand the logic of the system (product). For further analysis we also use Fault Tree Analysis (FTA) and Failure Mode and Effects Analysis (FMEA). Fault Tree Analysis (FaultTreeAnalysis) Simply put is the product (system) the most undesirable fault as the goal of fault analysis, the selected product
