Projects

  • Optimierung von Logistikketten in der Lebensmittelindustrie

    (Third Party Funds Group – Sub project)

    Overall project: SHIELD - Sichere heimische Bio-Lebensmittel durch sensorische Detektionsverfahren
    Term: 01-07-2021 - 30-06-2024
    Funding source: Bayerische Forschungsstiftung
    URL: https://www.bayfor.org/de/unsere-netzwerke/bayerische-forschungsverbuende/forschungsverbuende/association/shield.html
    Abstract

    Aufbauend auf der Expertise der am Projekt beteiligten Industriepartner entwickeln wir mathematische Optimierungsmodelle und Lösungsalgorithmen, die in der Lage sind, die gesamte Logistikkette in den Blick zu nehmen und so effizient wie möglich zu gestalten. Die intelligente Kombination solcher Verfahren mit modernen Methoden der Qualitätssicherung und datengetriebenen Absatzprognosen erlaubt eine Unterstützung der Fachplaner in einem Lebensmittel- oder Handelsunternehmen bei ihren Planungsaufgaben.
