Abstract: According to an example, a method for supplier quantity selection may include receiving a plurality of supplier offers for one or more items to be procured by a manufacturer, and determining whether the supplier offers include price uncertainty and a most favored customer (MFC) clause. Based on the determination that the supplier offers include price uncertainty and the MFC clause, the method may include evaluating the supplier offers by analyzing the price uncertainty and the MFC clause using a stochastic multi-stage model. The method may further include determining, by a processor, an allocation of all or part of each of the supplier offers to minimize purchase price of the one or more items based on the evaluation of the supplier offers.
