需求未知的车辆服务定价研究

Learning to Price Vehicle Service with Unknown Demand

Haoran Yu, Ermin Wei, Randall A. Berry

摘要:

车辆服务提供商可以根据用户在不同起点-目的地对上的出行需求来制定服务价格。以往的车辆服务空间定价研究都是基于服务提供者了解用户需求的假设。在本文中,我们研究了一个垄断供应商谁最初不知道用户的需求,并需要学习它随着时间的推移,通过观察用户的反应,服务价格。我们设计了一个定价和车辆供应政策,考虑到勘探之间的权衡(即,学习需求)和利用(即,最大化供应商的短期收益)。考虑到供应商需要确保每个位置的车流平衡,其针对不同起讫点对的定价和供应决策是紧密耦合的。这使得从理论上分析我们政策的绩效具有挑战性。我们分析了供应商的预期时间平均收益之间的差距,根据我们的政策和千里眼的政策,使决策的基础上完整的信息的需求。我们证明了在运行我们的策略D天后,预期时间平均收益的损失最多可以是O((ln D)^0.5 D^(-0.25)),随着D接近无穷大,它衰减到零。

英文摘要:

It can be profitable for vehicle service providers to set service prices based on users' travel demand on different origin-destination pairs. The prior studies on the spatial pricing of vehicle service rely on the assumption that providers know users' demand. In this paper, we study a monopolistic provider who initially does not know users' demand and needs to learn it over time by observing the users' responses to the service prices. We design a pricing and vehicle supply policy, considering the tradeoff between exploration (i.e., learning the demand) and exploitation (i.e., maximizing the provider's short-term payoff). Considering that the provider needs to ensure the vehicle flow balance at each location, its pricing and supply decisions for different origin-destination pairs are tightly coupled. This makes it challenging to theoretically analyze the performance of our policy. We analyze the gap between the provider's expected time-average payoffs under our policy and a clairvoyant policy, which makes decisions based on complete information of the demand. We prove that after running our policy for D days, the loss in the expected time-average payoff can be at most O((ln D)^0.5 D^(-0.25)), which decays to zero as D approaches infinity.
