Fleet sizing and charger allocation in electric vehicle sharing systems

In this paper, we propose a closed queueing network model for performance analysis of electric vehicle sharing systems with certain number chargers in each neighborhood. Depending on the demand distribution, devise algorithms to compute optimal fleet size and required maximize profit while maintaining quality service. We show that is concave respect at charging point. If more are installed within city, it can not only reduce size, but also improves availability vehicles all points city. further through simulation two slow may outperform one fast charger when variance time becomes relatively large comparison mean time.
