Josef Ressel-Zentrum für Heuristische Optimierung

In vielen Bereichen der erzeugenden Industrie ergeben sich Problemstellungen, die mit klassischen Methoden der Mathematik und Informatik nicht zufriedenstellend gelöst werden können. Repräsentativ hierfür sind im Ressel-Zentrum adressierte Herausforderungen der beteiligten Unternehmen bei denen Produktions- und Verarbeitungsprozesse durch intelligente Algorithmen optimiert werden sollen.
Konkrete Aufgaben bestehen dabei in der Identifikation von Zusammenhängen, welche physikalisch nicht exakt bekannt und oft hochgradig nichtlinear sind. Werden Einflussfak-toren und Auswirkungen in umfangreichen Datenbeständen erfasst, so können diese rele-vanten Zusammenhänge mit dem Ziel eines besseren Prozessverständnisses und einer darauf aufsetzenden Prozessoptimierung identifiziert werden. Weitere konkrete Heraus-forderungen im Partnerkonsortium ergeben sich im Bereich der Produktionsoptimierung, bei der Faktoren wie Maschinenauslastung oder Termintreue nur durch heuristische Methoden optimiert werden können.
