价格与产品组合联合决策的马尔可夫链选择模型下的收益管理

Revenue Management Under the Markov Chain Choice Model with Joint Price and Assortment Decisions

Anton J. Kleywegt, Hongzhang Shao

摘要:

寻找最优的产品价格和产品组合是收益管理中的两个基本问题。通常情况下,卖方需要共同确定价格和分类,同时管理容量有限的资源网络。然而,目前还没有一种简单易行的方法来有效地解决这样的问题。现有的研究静态联合优化的价格和品种不能考虑资源约束。然后,我们研究的收益管理问题的资源约束和价格的界限,其中的价格和产品销售需要共同确定随着时间的推移。我们表明,在马尔可夫链(MC)选择模型(它包含了多项罗吉特(MNL)模型),我们可以重新选择为基础的联合最优化问题作为一个易于处理的凸二次曲线最优化问题。我们还证明了一个最优解与一个恒定的价格向量存在,即使资源的约束。此外,当不存在资源约束时,同时具有固定分类和价格向量的解决方案可能是最优的。

英文摘要:

Finding the optimal product prices and product assortment are two fundamental problems in revenue management. Usually, a seller needs to jointly determine the prices and assortment while managing a network of resources with limited capacity. However, there is not yet a tractable method to efficiently solve such a problem. Existing papers studying static joint optimization of price and assortment cannot incorporate resource constraints. Then we study the revenue management problem with resource constraints and price bounds, where the prices and the product assortments need to be jointly determined over time. We showed that under the Markov chain (MC) choice model (which subsumes the multinomial logit (MNL) model), we could reformulate the choice-based joint optimization problem as a tractable convex conic optimization problem. We also proved that an optimal solution with a constant price vector exists even with constraints on resources. In addition, a solution with both constant assortment and price vector can be optimal when there is no resource constraint.
