Abstract
In this paper, extended formulations for stochastic uncapacitated lot-sizing problems with and without backlogging are developed in higher dimensional spaces that provide integral solutions. Moreover, physical meanings of the decision variables in the extended formulations are explored and special cases with more efficient formulations are studied.
