Abstract: The traditional operational cases in the experience sharing and the disposal efficiency are relatively passive, in addition, the similar events in the operational field have a high probability of repetition and great differences in the characteristics of the disposal. For this situation, we present a case analysis pyramid model using library construction method, which is based on vectorization and hierarchical knowledge extraction, to complete the automatic changes from operating standards and events bases to case material library, then to case teaching library. Based on the pyramid model, through the introduction of improved predict analytical methods, case-based reasoning “5R” model and the “4S” case teaching model, this paper improved the related applications such as early warning and forecasting, decision supporting and case teaching, building active operational case system. Through the implementation of the whole system, practical results show that the proportion of similar events was declined year by year, event responsing time and handling time were shortened, and the quality of operational service was enhanced significantly.
