【Abstract】 With the rapid development and popularization of mobile and wireless communication technologies, dynamic ride-sharing platforms, as pioneers in a sharing economy context, provide on-demand shared transportation services and are disruptively changing the transportation industry. First, we study the matching problem for ride-sharing platforms, in which the platforms match passengers and drivers in real time considering multiple objectives such as platform revenue, pick-up distance, and service quality. It is a multi-period multi-objective online optimization problem. 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. We prove that the proposed adaptive matching policy can achieve the “target-based optimal solution”, i.e., the solution that minimizes the Euclidean distance to any pre-determined multi-objective target, and demonstrate its good performance through numerical experiments and implementation using real data from a ride-sharing platform. Second, we propose a framework to study the coordination of platform demand and supply using prices and wages. The platforms use earnings-sensitive drivers with heterogeneous reservation wage that serve time- and price-sensitive passengers with heterogeneous valuations of the service. We propose a queueing model with endogenous supply and endogenous demand and present steady-state performance in equilibrium to determine the optimal price and wage that maximize the platform’s profit or social welfare.
