摘　　要：考虑随机产出随机需求下单供应商-单零售商的两级供应链系统,研究回购契约在双随机环境下协调供应链的作用,分别建立基于批发价格契约与回购契约的供应链分散决策模型,比较两种契约安排下的供应商定价、零售商订货决策以及供应链各方利润,揭示影响回购价格的关键因素,分析供应商产出波动、需求波动分别对供应商定价决策、零售商订货决策以及供应链各方利润的影响。研究表明,回购契约能有效协调随机产出随机需求下的供应链运作,且回购契约对供应链效率改善随着供应商产出波动的增加而提高。A two - stage supply chain with single supplier and single retailer is considered under random yield and uncer- tain demand. The role of buy - back contract in the coordination of supply chain is studied ; decentralized decision models of supply chain are built under buyback contract and wholesale price contract. The pricing decision of the supplier, the or- dering decisions of the retailer and the profits of all parts in supply chain, are compared under two cases. The key faetors influencing buy - back price are revealed, and the impacts of the fluctuation of yield and demand on the pricing and orde- ring decision of supply chain, and the profits of all parts in supply chain, are analyzed. It is showed that buy - back con- tract can effectively coordinate supply chain under random yield and uncertain demand, and the effect of buy - back con- tract on improving the efficiency of supply chain increases with the increase of the fluctuations of random yield.
