“…As for the model library , we may set the library as an open frame and firstly put some typical models into the library, such as the linear regression model, the non-linear model, the time series model [5] (AR, MA, ARMA, ARX, ARXMA, etc), the polynomial model and the dynamicmeasurement model [8] for continuous variable dynamic system and the Petri net model, the automaton model, and Markov chain model for discrete event dynamic model. When the library being used, open frame can be helpful to update and to add new models into the library on-line.…”
