Developing exact and heuristic models and algorithms to solve large-scale logistics problems, for example in facility location, districting, or service scheduling, taking time dynamic, uncertainty and reliability issues into account. Combining different disciplines from mathematics and computer science, like combinatorial optimization, complexity theory, algorithmic design, computational geometry, and calculus, to obtain structural results and exact solution approaches, e.g., for location problems with continuous demand.
