内容摘要:
we propose a general framework to study the on-demand shared ride-sourcing transportation systems and summarize corresponding research problems and methodologies. we then focus on multi-objective matching between demand and supply. the platforms match passengers and drivers in real time without observing future information, considering multiple objectives such as pick-up time, 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 guarantees 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 industrial testing using real data from a ride-sourcing platform, we demonstrate that our approach is able to arrive at a delicate balance among multiple objectives and bring value to all the stakeholders in the ride-sourcing ecosystem.
