Kurzprofil

Christian Gahm, geb. 1979, studierte an der Universit?t Augsburg Angewandte Informatik mit den Schwerpunkten Softwaretechnik und Programmiersprachen sowie Kommunikationssysteme und Systemnahe Informatik. Seit November 2006 ist er wissenschaftlicher Mitarbeiter am Lehrstuhl für Production & Supply Chain Management. Seit seiner Promotion 2010 leitet Herr Gahm die Forschungsgruppe ?Production Management“?und strebt seine Habilitation an. Im Bereich Forschung befasst sich Herr Gahm unter anderem mit der Entwicklung von problemspezifischen Scheduling-Algorithmen, energie-orientierter Produktionsplanung und Decision-Support- bzw. Advanced-Planning-Systemen in der betrieblichen Praxis. Neben klassischen Lehrveranstaltungen (Vorlesungen und Seminare) aus den Bereichen Supply Chain Management und Operations Management ist Herr Gahm auch für die Organisation und Durchführung des Lehrangebots bzgl. ERP-Systeme (SAP) an der wirtschaftswissenschaftlichen Fakult?t verantwortlich. Der Wissenstransfer von Forschungsergebnissen und neusten Methoden in die betriebliche Praxis ist ihm ein gro?es Anliegen und hat in vielen Praxisprojekten bereits zu gro?en Erfolgen geführt.
