摘　　要：本文以汽车零部件的失效诊断为技术背景,根据失效诊断技术过程,提出了失效诊断数据仓库的功能架构,描述了集成化建模方法,对数据的收集、集成、存储、管理等方面进行研究,以提高数据仓库的准确度,并提供了基于此架构的系统实现案例,指出了要进一步研究的问题。为汽车零部件失效诊断数据仓库建设提供了一种实用而有效的新途径。Under the technical background of diagnosing of automobile parts invalidation, the process of invalidation diagnosing was analyzed, and the functional structure of data warehouse of invalidation diagnosing was proposed. The integrated methodology of mod- eling was described, and research on the data accuracy, data collect, data integration, data memory and sustainable application of in- terface data was carried out, in order to improve the accuracy of data warehouse. Some cases of actualized systems based on this framework were discussed, and issues remaining to be addressed in the future were put forward. A new and practicable method of constructing the data warehouse for diagnosing automobile parts invalidation was provided.
