Purpose This paper addresses a supply contract problem for a two-echelon supply chain (SC) consisting of a single manufacturer and a single retailer where products are sold during a selling season. A buyback supply contract is a supply contract strategy to tackle a double marginalization problem caused by a commonly-used wholesale contract. This paper addresses the problems associated with a profit share between manufacturers and retailers, and the retailer's tendency toward risks.
Methods The relationship between the retailer's share of an SC's profit, and the optimal combination of wholesale and buyback price is examined. A revised buy-back contract is presented for risk-averse retailers where the retailer’s profit share is maintained while profit variability is controlled under a target level. Mean-variance analysis is applied in the new buyback algorithm.
Results Numerical examples are given and the performance of the revised buyback contract is examined. The effect of changes in wholesale prices and buyback prices on total supply chain profits is examined through numerical analyses.
Conclusion The presented algorithm makes it possible to realize a target profit while satisfying a retailer’s risk level. Future works about supply contracts are discussed for real-world market environments.
