Avec 300 nouvelles demandes par an, Constellium Valais<\/a> produit une grande vari\u00e9t\u00e9 d’objets en aluminium par le proc\u00e9d\u00e9 d’extrusion. Chaque nouvelle demande n\u00e9cessite un effort d’ing\u00e9nierie important, notamment pour d\u00e9terminer si le profil souhait\u00e9 peut \u00eatre fabriqu\u00e9 et \u00e0 quel co\u00fbt, et pour concevoir l’outillage et la recette de production. L’une des t\u00e2ches essentielles de cette analyse consiste \u00e0 rechercher des profils similaires \u00e0 celui demand\u00e9 dans l’historique de production afin de compl\u00e9ter l’exp\u00e9rience personnelle des sp\u00e9cialistes qui \u00e9tudient sa fabricabilit\u00e9 et pr\u00e9voient la pression de la presse pendant l’extrusion.<\/p>\n

Le projet P3 (Press Pressure Prediction) d’Innosuisse, coordonn\u00e9 par le groupe de recherche SPL de la HEI Valais et en partenariat avec Constellium Valais SA, visait \u00e0 utiliser les technologies de l’IA pour aider les experts \u00e0 r\u00e9aliser l’\u00e9tude de faisabilit\u00e9. Cet objectif a \u00e9t\u00e9 atteint gr\u00e2ce au d\u00e9veloppement d’outils performants de recherche de profils similaires dans l’historique de production ainsi que de pr\u00e9diction de la pression de pressage. A l’Idiap, le groupe Perception & Activity Understanding a particip\u00e9 \u00e0 cette collaboration.<\/p>\n

Comment cela fonctionne-t-il ? <\/strong><\/p>\n

Pour obtenir les donn\u00e9es n\u00e9cessaires aux m\u00e9thodes d’IA, Constellium a d\u00e9ploy\u00e9 des efforts consid\u00e9rables pour r\u00e9cup\u00e9rer toutes les donn\u00e9es de production, y compris plus de 1 200 \u00e9bauches de profils d\u00e9j\u00e0 fabriqu\u00e9s et les donn\u00e9es de 730 000 extrusions de ces profils. Ces informations ont \u00e9t\u00e9 trait\u00e9es pour concevoir et entra\u00eener deux mod\u00e8les : un r\u00e9seau neuronal qui extrait une signature caract\u00e9ristique de la forme d’un profil \u00e0 partir de son image et trouve rapidement des profils similaires dans la base de donn\u00e9es, et un r\u00e9seau neuronal conditionnel qui pr\u00e9dit la pression pendant l’extrusion pour une vitesse et une temp\u00e9rature sp\u00e9cifiques.<\/p>\n

Enfin, une interface graphique d\u00e9velopp\u00e9e par HEI a \u00e9t\u00e9 mise en place pour permettre aux ing\u00e9nieurs et aux op\u00e9rateurs d’utiliser facilement les mod\u00e8les en fonction de leurs besoins quotidiens.<\/p>\n

Les experts de Constellium Valais sont tr\u00e8s satisfaits de ce nouvel outil, car il leur a permis de trouver rapidement des profils similaires \u00e0 celui \u00e0 \u00e9valuer et leur a fourni de nouveaux moyens d’analyse pour simuler rapidement la pression tout au long du processus d’extrusion. Ce projet est une collaboration fructueuse entre la recherche et l’industrie valaisanne et les partenaires de Constellium ont trouv\u00e9 de nouvelles fa\u00e7ons d’utiliser et d’am\u00e9liorer les pr\u00e9dictions des mod\u00e8les.<\/p>\n

A propos de l’Idiap<\/strong><\/p>\n

L’Institut de recherche Idiap<\/a> a apport\u00e9 des contributions significatives au domaine de l’IA et au canton du Valais. Ses recherches pionni\u00e8res ont contribu\u00e9 \u00e0 fa\u00e7onner le d\u00e9veloppement des technologies de l’IA, et son engagement en faveur de l’\u00e9ducation et de la sensibilisation de la population a favoris\u00e9 l’innovation et la croissance dans la r\u00e9gion. Alors que le domaine de l’IA continue d’\u00e9voluer, l’Idiap est certain de rester \u00e0 la pointe de la recherche et de l’innovation, ouvrant la voie \u00e0 la prochaine g\u00e9n\u00e9ration de technologies d’IA.<\/p>\n","protected":false},"excerpt":{"rendered":"
