On the Wagner-Whitin Lot-Sizing Polyhedron [PDF]
Mathematics of Operations Research, 2001 We study a family of unbounded polyhedra arising in the study of uncapacitated lot-sizing problems with Wagner-Whitin costs. We present a new proof of integrality based on completely characterizing the bounded faces of maximal dimension, and in particular showing that they are integral.
