集装箱班轮二维收益管理在线动态定价策略

为了在现实约束条件下最大化班轮公司收益,研究了集装箱海运二维收益管理多航段多箱型在线动态定价模型,提出了其最优在线动态定价策略,并且证明了模型价值函数的单调性及其上界.基于降维的思想提出了更为实际的启发式算法.在算例中分析了单航段单箱型、单航段多箱型和多航段多箱型3种情况下的最优动态定价策略,分析结果表明:在单航段单箱型的情况下,最优价格具有单调性;在单航段多箱型和多航段多箱型的情况下,最优价格不一定具有单调性.

Online dynamic pricing policy for two-dimensional revenue management of container liners

A stochastic model for online dynamic pricing with multiple segments and multiple container types of two-dimensional revenue management is brought forward to maximize the total revenue of a container liner company under the condition of the realistic constraints.Then the optimal online dynamic pricing policy is presented.The bound of the value function of the model is proved and a more practical heuristic algorithem is presented based on the thought of reducing the dimensionality.The dynamic pricing policies are analyzed in three different cases—where there are one segment and one container,where there are one segment and multiple container types and where there are multiple segments and multiple container types—in our numerical examples.The analysis results show that the optimal price is monotonic in the first case,but is not necessarily monotonic in the second and third case.
