Study of Supply Chain Coordination Considering the Participation of Upstream Members of the Supply Chain in Repurchase

Abstract

For the supply chain consisting of a single supplier and a single retailer, the contractual coordination strategy of introducing retailers and suppliers to participate in repurchase is introduced to break the traditional model of supply chain repurchase, and the contractual models of retailers participating in repurchase alone and retailers and suppliers participating in repurchase together are constructed for supply chain coordination. The comparison between the case of retailer participating in repurchase alone and the case of supplier and retailer participating in repurchase at the same time shows that both repurchase models have a coordination effect on the supply chain, it was also found that introducing retailers and suppliers to participate in repurchases at the same time has higher supply chain benefits than retailers participating in repurchases alone.
