报告题目:The Logic of Matching in Shared Transportation

特邀嘉宾:Hai Wang, Assistant Professor, Singapore Management University

主持人:陈喜群  浙江大学智能交通研究所

报告内容:We study the multi-period multi-objective online ride-matching problem, where the dynamic ride-sharing platform needs to match passengers and available drivers in real time without observing future information, considering multiple objectives such as pick-up distance, platform revenue, and service quality. We develop an efficient online matching policy that adaptively balances the trade-offs between multiple objectives in a dynamic setting and provide theoretical performance guarantee for the policy. We prove that the proposed adaptive matching policy can achieve the solution that minimizes the Euclidean distance to any pre-determined multi-objective target. Through numerical experiments and implementation using real data from a ride-sharing platform, we demonstrate that our approach is able to obtain a delicate balance between multiple objectives and bring value to all the stakeholders in the ride-sharing ecosystem comparing to benchmark policies: (1) drivers with higher service scores (i.e., drivers who provide better service) are dispatched with more orders and earn higher incomes; (2) passengers are more likely to be served by drivers with higher service scores, and passengers with higher order revenues are served with higher answer rates, at the expense of a small increase in pick-up distance; (3) the platform obtains a higher total revenue.

嘉宾简介:Dr. Wang received a bachelor degree from Tsinghua University, dual Master’s degree in operations research and transportation from MIT, and Ph.D. from MIT Operations Research Center. His research has focused on methodologies on operations research, data-driven modelling, computational algorithms, and machine learnings, and relevant applications in urban, transportation, and logistics systems. Particularly, he is interested in on-demand service and shared transportation systems. He has papers published in Transportation ScienceAmerican Economic Review Papers & ProceedingsManufacturing & Service Operations Management, and Transportation Research Part B: Methodological. He is serving as the guest-editor for the Special Issue on Innovative Shared Transportation in Transportation Research Part B, as reviewer for more than 20 academic journals, including Management ScienceTransportation ScienceM&SOMPOM, etc, and named as Chan Wui & Yunyin Rising Star Fellow by Transportation Research Board. During his Ph.D. at MIT, he also served as the co-President of MIT Chinese Students & Scholars Association and Chair of MIT-China Innovation and Entrepreneurship Forum.
