Abstract
For an n-period uncapacitated lot-sizing problem with stock upper bounds, stock fixed costs, stock overload and backlogging, we present a tight extended shortest path formulation of the convex hull of solutions with O\((n^2)\) variables and constraints, also giving an O\((n^2)\) algorithm for the problem. This corrects and extends a formulation in Section 4.4 of our article “Lot-sizing with production and delivery time windows”, Mathematical Programming A, 107:471–489, 2006, for the problem with just stock upper bounds.
