und Preis-Leistungs-Verh\u00e4ltnis. Die Corona-Pandemie verst\u00e4rkte Onlinebestellungen, doch R\u00fccksendungen verursachen hohe Kosten und CO2-Emissionen. Die Modeindustrie tr\u00e4gt \u00fcber 10 % zu den globalen CO2-Emissionen bei und muss diese bis 2030 um \u00fcber 50 % reduzieren, um das 1,5\u00b0C-Ziel zu erreichen. Deutschland f\u00fchrt mit bis zu 50 % Retouren im europ\u00e4ischen Vergleich. Gesetze wie die \"Obhutspflicht\" sollen der Vernichtung retournierter Ware entgegenwirken, k\u00f6nnten jedoch b\u00fcrokratischen Aufwand f\u00fcr H\u00e4ndler bedeuten. Datengetriebene L\u00f6sungen, insbesondere der Einsatz von Reinforcement-Learning, bieten eine pr\u00e4ventive Alternative zur Reduzierung von Retouren. Ein MAB-Konzept (multi-armed bandit) wird entwickelt, um das Recommender-System mittels Reinforcement-Learning zu optimieren. Ziel ist eine automatisierte Anpassung an ver\u00e4nderte Marktsituationen, um den Revenue per User um 8-20 % zu steigern und die Retourenquote um 10 % zu senken. Die Kooperation mit dem Institut f\u00fcr Informationsverarbeitung (TNT) der Leibniz Universit\u00e4t Hannover f\u00f6rdert Innovation und Wissenstransfer. Perspektivisch soll das Recommender-System auf andere E-Commerce-Bereiche ausgeweitet werden, um Arbeitspl\u00e4tze zu schaffen und die regionale Wirtschaft in Niedersachsen zu st\u00e4rken.<\/p>\r\n
