Abstract

In this paper a neural network ap­ proach to the factory dynamics modelling problem is discussed. A recurrent high-order neural net­ work structure (RHONN) is employed to identify the manufacturing cell dynamics, which is supposed to be unknown. The model is constructed in such a way that enables the design of a controller which will force the model and thus the original cell to display the required behaviour. Buffer states as well as con­trol input signals are transformed into continuous ones so as to be conformant with the RHONN as­ sumptions. A case study demonstrates the approx­imation capabilities of the proposed architecture.
