Title: The Application Of Valid Inequalities To The Multi-stage Lot-sizing Problem
Author: Clark A.R.
Armentano V.A.
Abstract: A capacitated multi-stage lot-sizing problem for general product structures with setup and lead times is considered. The problem is formulated as a mixed integer linear program and valid inequalities that are high dimension faces of the problem's convex hull are identified. A fast separation algorithm is developed to iteratively select those inequalities that cut off the solution of the linear programming relaxation. The resulting much improved lower bounds are used in a Branch-and-Bound algorithm. Computational test results are presented. © 1995.
