共享移动按需服务的动态定价

Dynamic Pricing in Shared Mobility on Demand Service

Han Qiu, Ruimin Li, Jinhua Zhao

摘要:

我们考虑一个利润最大化的问题,在城市移动按需服务,其中运营商拥有一个车队,提供独家和共享的行程服务,并动态地确定报价。运营商希望在了解出行者偏好和未来出行需求分布的基础上,找到一种定价策略,使在一个特定时段(即一天)内多次出行的总运营利润最优。该问题首先在动态规划框架内进行了阐述和分析,提出了一种结合参数化铺开策略和随机最优化的通用方法。基于离散选择的价格最优化模型,然后使用的请求水平的最优判定问题,并导致一个实用的和计算易处理的算法的问题。我们的算法进行了评估,在城市交通网络在廊坊,中国的模拟实验,它被证明产生相当高的利润比天真的策略。进一步的分析表明,这种方法也导致更高的拥挤水平和较低的服务能力在城市交通系统中,这突出了需要政策干预,平衡私人利润和系统水平的最优性。

英文摘要:

We consider a profit maximization problem in an urban mobility on-demand service, of which the operator owns a fleet, provides both exclusive and shared trip services, and dynamically determines prices of offers. With knowledge of the traveler preference and the distribution of future trip requests, the operator wants to find the pricing strategy that optimizes the total operating profit of multiple trips during a specific period, namely, a day in this paper. This problem is first formulated and analyzed within the dynamic programming framework, where a general approach combining parametric rollout policy and stochastic optimization is proposed. A discrete-choice-based price optimization model is then used for the request level optimal decision problem and leads to a practical and computationally tractable algorithm for the problem. Our algorithm is evaluated with a simulated experiment in the urban traffic network in Langfang, China, and it is shown to generate considerably higher profit than naive strategies. Further analysis shows that this method also leads to higher congestion level and lower service capacity in the urban traffic system, which highlights a need for policy interventions that balance the private profit making and the system level optimality.
