ODC方法在故障树分析中的应用研究

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 integrity 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 construction is proposed. Then by an example the application of the rapid method of the faults tree construction is simply introduced. At last the method is used in the project to construct faults tree and it proves the efficiency and accuracy of the rapid method.
