Effects of retailer information sharing on collecting modes of closed-loop supply chain

This research studies the effects of information sharing on the choices of collecting modes by one manufacturer.In a centralized collecting mode,one supply chain model is developed with information sharing,and three decentralized collecting models(the retailer,manufacturer and third party collecting models) are developed without information sharing and with information sharing respectively.The results show that: 1) Forecasting information sharing would damage the retailer's profit,but the profit of the supply chain with information sharing is higher than without information sharing in the manufacturer collecting mode;2) A mechanism of information sharing which compensates the retailer is developed to motivate the retailer to share his information with the manufacturer;3) The forecast information accuracy and the price of used products have much effect on information sharing strategies of the retailer and the choices of the collecting modes for the manufacturer.
