供应链中基于信息更新的订货时间及价格联合决策研究

文章考虑在信息可更新的情况下,由一个制造商和一个零售商组成的供应链中订货时间及价格的联合决策问题.在模型中,制造商为零售商提供多次订货时间选择及相应的订货价格,而零售商可以在销售季节开始前自由选择订货时间并享受相应的价格.文章以不同订货时间对信息更新程度的影响为着眼点,将订货时间作为内生决策变量,突破了已有文献中仅限于两次订货时间选择的局限,分别从集中决策和分散决策两个角度建立供应链节点企业的利润模型,并在分散决策情况下引入收益共享契约,寻找帕累托改进.最后通过数值试验证明了该模型的有效性.

Joint Decision on Timing and Pricing for Ordering under Information Updating in a Supply Chain

This paper considers the joint decision on timing and pricing for ordering in a supply chain consisting of one manufacturer and one retailer with continuous information updating on retailer's side.The manufacturer offers a menu with multiple choices on timing and pricing for ordering.Before selling season starts,according to the menu,the retailer decides when to place an order and enjoys the corresponding price.We consider timing for ordering as decision variable with respect to its effects on the degree of information updating,which extends the existing literature by removing the constraint of fixed ordering time.We study each entity's profit under both centralized and decent ralized systems.In the decentralized system,we incorpo rate revenue sharing contract to find Pareto improvement.Numerical examples are also provided to illust rate the effectiveness of our coordinating mechanism.
