Welcome to the website of the group headed by Jun.-Prof. Dr. Kevin Tierney at the University of Paderborn. Our research focuses on the intersection of real world problems, optimization and decision support systems. In particular, we specialize in solving optimization problems within the container shipping industry and in the general area of maritime transportation. Our goal is to develop algorithms and systems that help make global trade more efficient, both in terms of its cost and its environmental impact. We are associated with the Decision Support & Operations Research Lab.
