To deal with this problem, we propose a preprocessing system for the operation data of a heating furnace. It employs the self-adaptive fuzzy neural network (FNN) method to predict the immeasurable data, provides the data-filtering, and rejects abnormal data by case-based reasoning. It uses the case-based reasoning (CBR) method to build a new mechanism for data replacement and modification. This intelligent preprocessing system has been successfully applied to a heating furnace in an iron-and-steel company, achieving desirable production results. Key words: heating furnace; data pre-procession; filtering; fuzzy neural network; case-based reasoning 1 (Introduction) , , . , . , , , . , , , . , . , . . , , ; , , . , , , . , , . , , ,
