In this paper, an intelligent model constructed with Fuzzy TS dynamic Nonlinear Autoregressive with exogenous input (NARX) is introduced for process state identification and behavior prediction for complex processes based on the results in [14] [15]. An optimization schemes are also investigated for model adaptability to cover time depending process changes. After model optimization, the process difference process state and its input data state can be determined based on the classified process state and input variables. Data mining is employed to discover valuable knowledge and rules hided in process data. Finally, a real case is studied for products supply process diagnosis and forecasting with this model. It indicates that the model has good performance for process state classification, identification and process behaviors prediction, as well as business rules extraction for making decision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
