Progressive hedging for multi-stage stochastic lot sizing problems with setup carry-over under uncertain demand
Manuel Schlenkrich, Jean-François Cordeau, Sophie N. Parragh
We investigate multi-stage demand uncertainty for the multi-item multi-echelon capacitated lot sizing problem with setup carry-over. Considering a multi-stage decision framework he…
