Title: Simple MIPs and Lot-Sizing: New Results and Old Favorites
Talk venue: Auditório do INESC Porto, Campus da FEUP. 

*Abstract:*   We introduce and relate a simple mixed set, the mixing set, a variety of single-item lot-sizing problems
and a common generalization, the network dual MIP (please see PDF: 

http://www.dcc.fc.up.pt/~jpp/optimization/index.php/WOW_list <http://www.dcc.fc.up.pt/%7Ejpp/optimization/index.php/WOW_list>

We then examine two problems: constant capacity lot-sizing with (lost)
sales and uncapacitated two-level lot-sizing in series, and present algorithms and tight extended formulations. We
then return to two old results showing the  remarkable versatility of mixing sets in providing compact formulations
for a multi-item lot-sizing problem with joint  set-ups and a single-item problem with non-decreasing capacities..
