  The prepacking problem consists in putting a product of different sizes, for instance T-Shirts, into packs sent to stores to satisfy demand. However, to reduce costs, the number of different pack configurations is limited. Different approaches were tried such as a MIP, constraint programming and a heuristic.

  Dynamic Task Assignment in a Warehouse

  Optimization in Fashion Assortment Planning

  • Éric Prescott Gagnon, JDA Software
  • Vincent Raymond, presenter, JDA Software
  • Marc Brisson, JDA Software
  • Marie-Claude Côté, JDA Software
  • Gabrielle Gauthier Melançon, JDA Software

  Planning an assortment in fashion consists in selecting the best set of items to be carried in each store of a chain for a future season based on user-defined constraints. To solve this problem, a genetic algorithm, a MIP model and new approaches to create new items have been developed.

  The slides are in English but will be presented in French.
