摘要

Process modelling refers to the development of a process model that serves to provide the input-output relationship of a process, while process optimisation provides the optimum operating conditions of a process for a high-yield, low-cost and robust operation. Normally, process modelling is a starting point of process optimisation. Regression analysis is used to develop process models, while the Karush-Kuhn-Tucker (K-K-T) conditions, response graphs and contour plots are used in process optimisation. The application of the method to the modelling and optimisation of impact toughness is described. To illustrate the proposed approach, experimental results are provided.
