Management Science, 1982 In this Note we present an alternative formulation to the MRP lot sizing model of Steinberg and Napier (SN) (Steinberg, E., H. A. Napier. 1980. Optimal multi-level lot sizing for requirements planning systems. Management Sci. 26 (2) 1258–1271.). The alternative is more parsimonious and the notation less cumbersome.

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.
