摘　　要：针对随机需求依赖价格的情况,由限制性退货契约和销售回扣契约构成的联合契约,能够确保供应链协调.然后,在加法和乘法需求模式下,当随机需求分布具有递增的失败率,供应链存在唯一最优的定价-订购联合决策,并给出最优决策的解析表达式.最后,通过数值算例验证了本文结论的有效性.As for the random demands relying on price, supply chains can be kept in coordination due to the joint contract made by restrictive return contract and sales rebate contract. Under the addition demand mode and multiplication demand mode, it is concluded that supply chains own the only pricing - ordering decision, and the ontimal decision analytic expression is ~iven. The conclusion is oroved by numerical examples.
