Abstract: Aiming at the raw material resources allocation problem of two-stage supply chain constituted by one manufacturer and one retailer under asymmetric information,a optimization approach by combining game theory with quantity strategies was proposed.On this basis,the upgrade alternative raw material resources optimal allocation model was established.Through adjusting the product replacement rate and the quantity discount rate,the retailers was encouraged to share their private information,and the raw material resources needed for the production were allocated reasonably.Thus the maximum profits of supply chain node enterprises were realized.The numerical examples were presented to verify the results.The results showed that the alternative products resources allocation promotion was realized by using quantity discount strategies,and the expected profit of supply chain node enterprises had Pareto improvement.
