- PHD CONFIRMATION SEMINAR
- Speaker: Rasul Esmaeilbeigi, The University of Newcastle
- Title: Hierarchical location-routing problems in dairy industry
- Location: Room V205, Mathematics Building (Callaghan Campus) The University of Newcastle
- Time and Date: 10:30 am, Thu, 23rd Feb 2017
In this talk, we discuss our new approach to design reverse
logistics models for dairy industries, in particular whey products.
Whey is a by-product of cheese making with many applications spanning
from dairy and meat to pharmaceuticals. We develop a hierarchical
location-routing model for a whey recovery network design. In this
class of models, the location and routing decisions are made
simultaneously. As the problem is NP-hard, it may not be possible to
solve even the small-size instances efficiently. We suggest different
approaches such as adding valid inequalities and improving lower and
upper bounds to solve the problem in a reasonable amount of time.
