Researchers have developed a novel Semi-Markov Reinforcement Learning approach for managing large-scale electric vehicle ride-hailing fleets. This method ensures that dispatch, repositioning, and charging decisions strictly adhere to physical constraints like charger and feeder limits, even under uncertain demand and travel times. The system utilizes a masked actor to produce high-level intentions, which are then projected through a mixed-integer linear program to guarantee feasibility. Experiments on a New York City taxi dataset simulator demonstrated that this approach, named PD--RSAC, significantly outperformed baseline methods, achieving a net profit of $1.22 million while preventing any feeder-limit violations.
