Query: A comparison of non-stationary stochastic lot-sizing strategies   We consider the non-stationary stochastic lot sizing problem with backorder
costs and make a cost comparison among different lot-sizing strategies. We
initially provide an overview of the strategies and some corresponding solution
approaches in the literature. We then compare the cost performances of the
lot-sizing strategies on a common test bed while taking into account the added
value of realized demand information. The results of this numerical experience
enable us to derive novel insights about the cost performance of different
stochastic lot-sizing strategies under re-planning with respect to demand
realization.
