结合某汽车缸体加工自动线国产组合机床故障数据，采用基于决策实验室分析（DEMATEL）和解释结构模型法（ ISM）对其进行故障相关性分析。通过DEMATEL法计算故障相关子系统的相关度，明确相关故障的因果传递方向以及存在的影响关系，确定相关子系统的相关性排序；利用ISM构建递阶结构模型，明确故障相关子系统的相互影响及依存的逻辑结构，实现相关故障子系统的结构化和层次化，为故障诊断与故障定位提供依据。

On the basis of the failure data of assemble machine tools made in China from one type of auto -mobile cylinder processing line , a failure correlation analysis is conducted based on decision-making labo-ratory analysis (DEMATEL) and interpretive structure model (ISM).First, degree of association by DE-MATEL is calculated , and correlation and all relationships of correlative fault and determined correlation sort of related fault subsystems are analyzed .Next, a hierarchical structure model is constructed based on ISM, which can confirm the interrelationship of related fault subsystems and logical structure .By realizing the structured and hierarchical structure of fault systems , the basis for fault diagnosis and fault location are provided .
