| 摘 要： | Hong＆Lie在BimBaum重要度的基础上给出了两个底事件的联合重要度的算法，但是对计算结果分析得知此算法存在不足之处．对此提出了一种改良的联合重要度算法，并用改良前后的两种算法对同一棵故障树的底事件进行联合重要度计算，并将两种算法的计算结果进行对比分析，最终得出结论，改良后的联合重要度算法是合理的．

| Abstract: | Importance analysis is a significant component of fault tree quantitative analysis and an important concept in reliability theory.Based on the calculation results of BirnBaum importance,an improved algorithm on joint failure importance is proposed,and the detailed calculation of the importances is illustrated with an example of a fault tree.It proves that the improved algorithm is reasonable by comparing their results. |
