Most manufacturers or retailers must procure items or services necessary for their businesses, in anenvironment that typically includes a number of competing suppliers with varying cost structures, priceschemes, and capacities. In this paper, we consider the sourcing problem in which the buyer determinesthe sources that should be utilized and to what extent, in turn, dictating the total quantity available forthe buyer to sell/utilize, subject to stochastic demand/requirement. Our approach advocates not todetermine the quantity to be sourced a priori. We allow for capacitated sources and any cost structure inwhichfixed costs and quantity discounts are special cases. Some simpler versions of this problem areshown to be NP-hard in the literature. By proving that the order of the sources is irrelevant for theoptimal solution, we devise a dynamic programming model with pseudo-polynomial complexity tosolve the multiple supplier sourcing problem to optimality. We propose two extensions: one limits thenumber of suppliers, and the other allows multi-period sourcing.
