Forschung

Unsere Forschungsinteressen umfassen ein breites Themenspektrum in den Bereichen Supply Chain Management, Produktions- und Service Operations Management sowie Einkauf und Beschaffung. In diesen Bereichen arbeiten wir regelmäßig mit verschiedenen Unternehmen an praktischen Problemen zusammen. Methodisch setzen wir eine große Bandbreite an Techniken ein, von deskriptiven über prediktive bis hin zu präskriptiven Analytics.

Unsere Arbeiten werden regelmäßig in führenden internationalen akademischen Zeitschriften veröffentlicht, darunter Manufacturing and Service Operations Management, Management Science, Operations Research, Production and Operations Management, Journal of Operations Management, European Journal of Operational Research, Academy of Management Journal, MIT Sloan Management Review, und andere.
