This paper introduces a modified fuzzy decision tree model. Firstly, the data are fuzzed by the use of optimal division point with optimal division entropy. Secondly, uncertainty theory of fuzzy math is introduced and a tree is built according to uncertainty of classification and creation rule. Finally, each unit can be detected about whether or not it is a fraud according to rule match method.

介绍了一种改进的模糊决策二叉树模型，即采用最优分割熵方法确定最优割点来对数据模糊化，引入模糊数学中的不确定性理论，依据分类的不确定性建造树，生成规则，在此基础上利用规则匹配的方法检测任意的样本数据是否为欺诈数据。

In the paper, the importance of FTA is described, the quantitative analysis method of the FTA is introduced in detail. Then the paper takes a vehicle control system as the research object, expatiates the forming of the CPU board fault tree, the establishing of the mean event fault tree and the obtaining of the mean event fault probability, and realizes the element level fault orientation on the CPU board of the vehicle control system. The test indicates that the method is both valid and correct.

文章在介绍故障树分析法重要性的基础上，较详细地介绍了FTA的定量分析法，并以某车辆控制系统为研究对象，从CPU板故障树的构建、各中间事件故障树的建立和各子事件故障概率等方面出发，实现了车辆控制系统CPU板元件级的故障定位，实验表明了该方法的有效性和正确性。
