Integrated Scheduling and Routing in Logistics and Traffic

Abstract:
Intelligent route planning is a key ingredient in logistics and traffic. One wants to utilize the available logistics of traffic network in such a way that the total network load is minimized or the throughput is maximized. This lecture deals with these optimization problems with a combination of scheduling and dynamic network flow techniques. I will present several applications including our recent work on improved traffic guidance policies based on macroscopic optimization models and toll policies, and on optimizing ship traffic on the Kiel Canal. The latter is a project in cooperation with the German Federal Waterways and Shipping Administration.




Colloquium - 16:00

Cesar Ceballos - FU Berlin

Subword complexes, cluster complexes, and generalized multi-associahedra

Abstract:
We present a new family of simplicial complexes called multi-cluster complexes. These complexes generalize the concept of cluster complexes, and extend the notion of multi-associahedra to arbitrary finite Coxeter groups. We present combinatorial and geometric properties of these objects, as well as open problems and conjectures. This is joint work with Jean-Philippe Labbé and Christian Stump.
