The mechanisms involved in this process are  complex and material, geometry and operation  dependent. Usually, the setting of the extruder  operating conditions or the establishment of the  adequate screw geometry is based on trial-and-error.  A more efficient method consists in determining the  operating conditions or screw geometry that produces  the desired performance, i.e. to solve the inverse  problem. In this work a multi-objective optimization  methodology based on genetic algorithms is proposed  and used to perform an automatic optimization of the  single screw polymer extrusion process. For that  purpose a modelling package capable of considering  the relevant thermo-mechanical phenomena occurring  inside the extruder was developed and linked to the  referred optimization methodology. The computational  and experimental results obtained in real  optimization problems validated the methodology  proposed. This text can be used either by the  researchers interested in the extrusion process or  by the researchers only in using multi-objective  optimization.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838324128\"\u003e\u003ch3\u003eUsing Multi-Objective Evolutionary Algorithms\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838324128","offer_id":39499058806877,"sku":"9783838324128","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6b4ce4db-b0c2-4fd0-a484-b1ff1cec92d3.jpg?v=1768976373","url":"https:\/\/shop.autorenwelt.de\/products\/modelling-and-optimisation-of-single-screw-extrusion-von-antonio-gaspar-cunha","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
