A Metamodel based Multiple Criteria Optimization via Simulation Method for Polymer Processing
… processing of plastic parts, advanced computer simulation tools have been developed. Yet, the difficulty of optimizing polymer processes is that the performance measures (objectives) involved usually show conflicting behaviors. Therefore the best processing conditions for one performance measure …
