Abstract: A closed loop supply chain consisting of a single manufacturer and a single retailer is considered, the manufacturer is responsible for manufacturing and remanufacturing, the retailer is responsible for product sales and collection of waste products, the corresponding game model is established, and the coordination with revenue sharing contract is analyzed firstly. Then, the coordination with revenue sharing contract under emergency is studied. The results point out that the coordination of closed loop supply chain would be broken when the sale market size and the initial collection market size of waste products change simultaneity under emergency, so the revenue sharing contract is adjusted, the closed-loop supply chain has anti-emergency when the revenue sharing contract is adjusted. Finally, a numerical calculation example is given to verify the conclusion.

Key words: supply chain management, closed-loop supply chain, emergency, revenue sharing contract , coordination
