摘要: Engine assembly is a complex and heavily automated distributed-control process, with large amounts of faults data logged everyday. We describe an application temporal mining for analyzing fault logs in engine plant. Frequent episode discovery framework model-free method that can be used to deduce (temporal) correlations among events from the efficient manner. In addition being theoretically elegant computationally efficient, frequent episodes are also easy interpret form actionable recommendations. Incorporation domain-specific information critical successful manufacturing domain. show how knowledge incorporated using heuristic rules act as pre-filters post-filters discovery. The system described here currently one plants General Motors planned adaptation other plants. To best our knowledge, this paper presents first real, large-scale believe ideas presented help practitioners engineer tools analysis similar or related domains well.
