摘　　要：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 .
