摘要
为了减少构建软件故障树的成本,提高构建软件故障树的效率,保证软件故障树的完备性,将正交缺陷分类技术引入故障树分析,把典型缺陷类型按照ODC正交分类思想划分,构造了一个缺陷类型与缺陷基本原因对照表,并根据此表提出了一种故障树快速构建方法。通过一个实例介绍了快速故障树构建方法的应用。通过在项目中试用此方法构建故障树,表明了该方法的高效准确。
To reduce the cost of constructing faults tree, to increase the efficiency of constructing faults tree and to ensure the in- tegrity of the faults tree, The orthogonal defect classification is introduced into the FTA, dividing the typical fault types by ODC, constructing a fault type and basic reason table, and based on the table a new kind of rapid method of the faults tree con- struction is proposed. Then by an example the application of the rapid method of the faults tree construction is simply intro- duced. At last the method is used in the project to construct faults tree and it proves the efficiency and accuracy of the rapid method.
