IFORS Distinguished Lecture
Solving Transportation Problems by Integer Programming
Technische Universität Berlin, Germany
Transportation problems occuring in practice (such as: public mass transport by bus, train, or plane , dial-a-ride, track routing, scheduling of service vehicles, logistics, …) are much more complex tasks than what is usually called a “transportation problem” in the mathematical programming terminology. In this talk I will present an overview of some of the problems of this type that have been attacked using integer programming techniques by the transportation research group at the Konrad Zuse Zentrum and the DFG Research Center Matheon in Berlin. I will present solutions of very large scale instances from practice and indicate the savings that can result from the use of advanced mathematical solution technology. In my computational report I will particularly focus on vehicle scheduling and driver assignment in public transport.
