A decentralized supply chain is a network consists of multiple decision makers including the original equipment manufacturer (OEM), the upstream contract manufacturer (CM), retailers and downstream customers. Each of these entities has different information and incentive towards profit and cost priorities. The structure of decentralized supply chains are prevalent today with two growing trends of the manufacturers’ outsourcing practices and the retailers’ application of novel selling strategies. This dissertation is inspired and has been conducted in two themes under these two trends accordingly, with one focused on the OEM’s outsourcing decision making problems and the other on the retailer’s pricing and inventory decision making problems when they are applying newly-emerged selling strategies such as Group Buying selling. First, the OEM’s outsourcing supplier selection and order allocation decisions are studied under the effect of a quality-driven demand. Then the OEM’s in-house production and outsourcing decisions are investigated under a one-OEM-one-CM scenario with quality evolvement and competition. Finally, moving to the downstream side of the supply chain, a joint effect of group-buying selling and buyback contract has been considered under the supply chain coordination perspective.
