Description

This invention relates to vehicle dispatch management technology, and more particularly to a vehicle dispatch management device and a vehicle dispatch management method for managing the optimal placement locations of electric vehicles available for user use. Mobility services are defined as services that provide smooth transportation for users and goods using vehicles. Examples of mobility services include car-sharing services, which allow multiple users to share vacant vehicles parked in nearby parking lots for predetermined usage periods, and ride-sharing services, which involve multiple passengers sharing a vehicle. In recent years, with growing environmental awareness, electric vehicles have become incredibly widespread, and mobility services using electric vehicles are increasingly becoming integrated into society. Mobility services require efficient vehicle allocation planning to increase vehicle utilization while improving user (passenger) convenience. For example, Patent Document 1 below discloses a technology for predicting the demand for vehicles required when a predetermined event is held at a destination, for each specific area, and for moving vehicles according to the predicted demand.
