Feedback-control operators for improved Pareto-set description: Application to a polymer extrusion process
This paper presents a new class of operators for multiobjective evolutionary algorithms that are inspired on feedback-control techniques. The proposed operators, the archive-set reduction and the surface-filling crossover, have the purpose of enhancing the quality of the description of the Pareto-set in multiobjective optimization problems. They act on the Pareto-estimate sample set, performing...
متن کاملPredicting Extrusion Process Parameters Using Neural Networks
The objective of this paper is to estimate realistic principal extrusion process parameters by means of artificial neural network. Conventionally, finite element analysis is used to derive process parameters. However, the finite element analysis of the extrusion model does not consider the manufacturing process constraints in its modeling. Therefore, the process parameters obtained through such...
متن کاملExtrusion process control: modeling, identification, and optimization
Our work has been focused on developing a methodology for process control of bulk deformation—specifically, extrusion. A process model is required for control. We state the difficulties which exist with currently available models. An appropriate decomposition and associated assumptions are introduced which permit a real-time process model to be constructed via spectral approximation to solve th...
متن کاملNumerical Analysis of Az61 Magnesium Alloy Extrusion Process by Modified Equal Channel Angular Extrusion (ecae) Method
T. Bajor, M. Krakowiak, P. Szota, Czestochowa University of Technology, Czestochowa, Poland The paper presents the results of numerical modelling of AZ61 magnesium alloy hot deformation using modified ECAE method. The temperature-velocity conditions were analysed using FEM. The extrusion process was realised using the die with modified angular channel containing horizontal contracting zone in t...
متن کاملA Taguchi approach on optimal process control parameters for HDPE pipe extrusion process
High-density polyethylene (HDPE) pipes find versatile applicability for transportation of water, sewage and slurry from one place to another. Hence, these pipes undergo tremendous pressure by the fluid carried. The present work entails the optimization of the withstanding pressure of the HDPE pipes using Taguchi technique. The traditional heuristic methodology stresses on a trial and error appr...
