| 摘 要： | 利用基于割集的传统故障树分析(FTA)技术进行复杂系统部件重要度计算时，面临着计算结果不精确、计算效率低等缺点。用于辅助故障树分析的BDD(二元决策图)技术则具有计算效率高、结果精确、并可在计算机上有效进行计算等特点。主要介绍如何把BDD技术应用于系统部件的重要度分析，为系统部件重要度分析提供一种计算方法和分析手段。

| Abstract: | Fault tree analysis technique is often used to calculate the importance of the components. It is often faces limitations in terms of accuracy and efficiency when dealing with the large fault tree structures. The Binary Decision Diagram(BDD) technique which can be implemented on the computer efficiently has the characteristics of the high efficiency of calculation and precise result. This paper''s aim is to provide a calculation or analysis method to analyze the importance of the components by using the BDD technique. |
