公平分享:共享乘车和路由游戏的Shapley值

Fair Sharing: The Shapley Value for Ride-Sharing and Routing Games

Chaya Levinger, Noam Hazon, Amos Azaria

摘要:

拼车服务越来越受欢迎,对可持续环境至关重要。这种服务最适用的一种特殊情况是最后一英里变体。在该变型中,假设所有乘客位于相同的起始位置(例如,机场),并且每个乘客具有不同的目的地。共享乘车的主要问题之一是在乘客之间公平地分摊乘车费用。在本文中,我们使用Shapley值,这是合作博弈论中最重要的解决方案概念之一,用于公平地分摊共享乘车的成本。我们考虑两种情况。在第一种情况下,存在乘客下车的固定优先级顺序(例如,老人、受伤者等),并且我们展示了在这种设置下有效计算Shapley值的方法。我们的结果也适用于路由游戏中的Shapley值的有效计算。在第二种情况下,没有预定的优先顺序。我们表明,Shapley值不能有效地计算在这种设置。然而,大量的模拟表明,我们的方法为第一种情况下可以作为一个很好的代理第二种情况下,优于其他已知的代理。

英文摘要:

Ride-sharing services are gaining popularity and are crucial for a sustainable environment. A special case in which such services are most applicable, is the last mile variant. In this variant it is assumed that all the passengers are positioned at the same origin location (e.g. an airport), and each have a different destination. One of the major issues in a shared ride is fairly splitting of the ride cost among the passengers. In this paper we use the Shapley value, which is one of the most significant solution concepts in cooperative game theory, for fairly splitting the cost of a shared ride. We consider two scenarios. In the first scenario there exists a fixed priority order in which the passengers are dropped-off (e.g. elderly, injured etc.), and we show a method for efficient computation of the Shapley value in this setting. Our results are also applicable for efficient computation of the Shapley value in routing games. In the second scenario there is no predetermined priority order. We show that the Shapley value cannot be efficiently computed in this setting. However, extensive simulations reveal that our approach for the first scenario can serve as an excellent proxy for the second scenario, outperforming other known proxies.
