An exact columngeneration approach for the lottype design problem
(2012)

Sascha Kurz
Miriam Kießling
Jörg Rambau
 We consider a fashion discounter distributing its many branches with
integral multiples from a set of available lottypes. For the problem of
approximating the branch and size dependent demand using those lots
we propose a tailored exact column generation approach assisted by fast
algorithms for intrinsic subproblems, which turns out to be very efficient
on our realworld instances.

Computational Bounds for Elevator Control Policies by Large Scale Linear Programming
(2013)

Stefan Heinz
Jörg Rambau
Andreas Tuchscherer
 We computationally assess policies for the elevator control problem by a new columngeneration approach for the linear programming method for discounted infinitehorizon Markov decision problems. By analyzing the optimality of given actions in given states, we were able to provably improve the wellknown nearestneighbor policy. Moreover, with the method we could identify an optimal parking policy. This approach can be used to detect and resolve weaknesses in particular policies for Markov decision problems.
