Applying a QoS-based fleet dimension method to reduce fleet emissions

Car sharing is a successful commercial application based on the collaborative consumption model. In this paper, we apply a recently proposed idea from a car sharing scheme to solve a fleet dimension problem emerging in utilities with large vehicle fleets. Within this framework, EVs are used to replace Internal Combustion Engine Vehicles (ICEVs) to reduce fleet pollutants. A small number of additional ICE vehicles are purchased to service long trips. The number of such vehicles are determined using a queueing model. Our studies show that pollutants can be significantly reduced while still providing a good quality of service (QoS) for staff to access vehicles.
