There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

TITLE: Decomposition of Multi-Period Inventory Routing Problems Via ADP
SPEAKER: Alejandro Toriello
ABSTRACT:
We investigate the possibility of generating good solutions to multi-period inventory routing problems by solving single-period sub-problems linked by inventory levels. The inventory tailing-off effect is counterbalanced by an approximate value function obtained via sampling and data fitting. We also study the fundamental question of whether approximate value functions allow us to shorten planning horizons so that solving multi-period problems becomes computationally tractable.
This is joint work with George Nemhauser and Martin Savelsbergh.
This is a joint SCL/DOS Seminar.
