      <title>The Integrated Size and Price Optimization problem</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/886</link>
      <description> We present the Integrated Size and Price Optimization Problem (ISPO)&#13;
  for a fashion discounter with many branches.  Based on a two-stage&#13;
  stochastic programming model with recourse, we develop an exact&#13;
  algorithm and a production-compliant heuristic that produces small&#13;
  optimality gaps.  In a field study we show that a distribution of&#13;
  supply over branches and sizes based on ISPO solutions is&#13;
  significantly better than a one-stage optimization of the&#13;
  distribution ignoring the possibility of optimal pricing.&#13;

      <title>An exact column-generation approach for the lot-type design problem</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/877</link>
      <description>We consider a fashion discounter distributing its many branches with&#13;
integral multiples from a set of available lot-types. For the problem of&#13;
approximating the branch and size dependent demand using those lots&#13;
we propose a tailored exact column generation approach assisted by fast&#13;
algorithms for intrinsic subproblems, which turns out to be very efficient&#13;
on our real-world instances.&#13;
