论文摘要
我们在本文中研究附加折扣的收入管理问题。该问题是由视频游戏行业的实践激发的,零售商在其中为也购买了核心产品(例如视频游戏机)的客户提供了选定的支持产品(例如视频游戏)的折扣。我们将此问题提出为优化问题,以确定不同产品的价格和附加折扣的产品选择。为了克服此优化问题的计算挑战,我们提出了一种有效的FPTA算法,该算法可以将问题大约解决到任何所需的准确性。此外,我们考虑了零售商对不同产品的需求功能的先验知识的环境中的收入管理问题。为了解决此问题,我们提出了一种基于UCB的学习算法,该算法将FPTA优化算法用作子例程。我们表明,我们的学习算法可以收敛到具有真正需求函数的最佳算法,我们证明收敛速率紧张直至某个对数项。此外,我们通过从tmall.com上一个流行的视频游戏品牌的在线商店收集的现实世界交易数据进行数值实验。实验结果说明了我们学习算法在各种情况下的稳健性能和快速收敛。我们还将我们的算法与不使用任何附加折扣的最佳策略进行了比较,结果显示了在实践中使用附加折扣策略的优点。
We study in this paper a revenue management problem with add-on discounts. The problem is motivated by the practice in the video game industry, where a retailer offers discounts on selected supportive products (e.g. video games) to customers who have also purchased the core products (e.g. video game consoles). We formulate this problem as an optimization problem to determine the prices of different products and the selection of products with add-on discounts. To overcome the computational challenge of this optimization problem, we propose an efficient FPTAS algorithm that can solve the problem approximately to any desired accuracy. Moreover, we consider the revenue management problem in the setting where the retailer has no prior knowledge of the demand functions of different products. To resolve this problem, we propose a UCB-based learning algorithm that uses the FPTAS optimization algorithm as a subroutine. We show that our learning algorithm can converge to the optimal algorithm that has access to the true demand functions, and we prove that the convergence rate is tight up to a certain logarithmic term. In addition, we conduct numerical experiments with the real-world transaction data we collect from a popular video gaming brand's online store on Tmall.com. The experiment results illustrate our learning algorithm's robust performance and fast convergence in various scenarios. We also compare our algorithm with the optimal policy that does not use any add-on discount, and the results show the advantages of using the add-on discount strategy in practice.
