Contract design of CLSC with recycled quantity affected by the interaction of recycling price and sales volume

On the base of the assumption that the recycled quantity of used products is affected by the interaction of recycling price and sales volume, this paper researches closed-loop supply chain's pricing and coordination, gives system members' optimal pricing and profits in decentralized decision and centralized decision and finds that reverse supply chain itself is in coordination and traditional forward supply chain is in incoordiantion under decentralized decision. Then it designs a revenue sharing contract which can coordinate closed-loop supply chain. At last, a numerical example is given to verify the conclusions drew in this paper.
