研究了有限时间内由一个供应商和一个零售商组成的易逝品供应链的定价和订货组合问题。产品的生命周期为两个阶段，每个阶段的需求是随机的，并且对价格敏感。在每个阶段，供应商首先确定批发价格，然后零售商决定订购量和零售价格。我们证明了非新鲜产品的最优定价策略只依赖于其库存量，而新鲜产品的最优定价策略和最优订货量只依赖于批发价格，并且它们之间存在一个常数关系。此外，有限时间内零售商和供应商之间的博弈等价于一个只有一个订单的单周期博弈。因此，最优策略在每个时期都是相同的。对于加法和乘法需求，我们进一步得到了计算最优策略的方程。将上述结果推广到无限时域情形和长寿命产品。最后给出了数值分析。爱思唯尔有限公司出版
The paper studies the combined problem of pricing and ordering for a perishable product supply chain with one supplier and one retailer in a finite horizon. The lifetime of the product is two periods and demand in each period is random and price-sensitive. In each period, the supplier determines first a wholesale price and then the retailer decides an order quantity and retail prices. We show that the optimal pricing strategy for the non-fresh product depends only on its inventory, and the optimal pricing strategy and the optimal order quantity for the fresh product depend only on the wholesale price and they have a constant relation. Moreover, the game between the retailer and the supplier for finite horizon is equivalent to a one period game with only one order. Thus, the optimal policies are identical at each period. For the additive and multiplicative demands, we further obtain equations to compute the optimal strategies. All of above results are extended into the infinite horizon case and longer lifetime products. Finally, a numerical analysis is given. Published by Elsevier Ltd.
