A multi-item production planning model with setup times: algorithms, reformulations, and polyhedral characterizations for a special case

MILLER, Andrew J.; NEMHAUSER, George L.; SAVELSBERGH, … - Center for Operations Research and Econometrics (CORE), … - 2001

We study a special case of a structured mixed integer programming model that arises in a number of applications. For the most general case of the model, called PI, we have earlier analyzed the polyhedral structure (Miller et al. [2000a]), including identifying facet-defining valid inequalities....
