供应链中供需协调及数量折扣定价模型

在非合作博弈条件下，供应链中的供需双方独立确定各自的最优批量，虽然其中一方处于最优决策之中，但整个供应链系统未达到最优，为使供应链得到优化、供需双方达到双赢的目的，提出了供需双方合作博弈条件下的最优批量及数量折扣定价模型，据此，可计算折扣的取值范围，再根据供需双方博弈力量以及对供应链业绩的贡献，即可确定合理的价格折扣。

Vendor-Purchaser Coordination and Quantity Discount Pricing Model in Supply Chain

Under the non-cooperative game, vendor and purchaser decide optimal lot size according to their own interests. One may be in an optimal condition, but the whole supply chain is not. To optimize the whole supply chain and attain the win-win goal, mutual optimal lot size models and the quantity discount pricing models were proposed under the cooperative game. The price discount can be determined with the models and by taking the bargaining powers and contributions of the both sides into consideration.
