摘　　要：通过分析和总结引发装备故障的环境因素构成及特点,设计一种软件故障案例框架表示模板。通过引入区域权重因子,提高了基于VSM(向量空间模型)的案例数值化表示的有效性和准确性。针对故障案例框架表示模板的故障症状中文描述特征项,提出了一种基于词典的相似性匹配算法,以此为基础,给出了基于案例推理(CBR)的装备软件故障诊断算法描述。By analyzing and summarizing environmental factors which can cause equipment fault,a new kind representation template based on frame and grouping patterns based on hierarchy are designed in this paper.Section weight is used to improve the effectiveness and accuracy of numerical representation of a fault case based on vector space model.Further,the last part of the paper gives the algorithm procedures to implement fault diagnosis based vector space model.
