Operation management apparatus, system, and operation management method

An operation management apparatus comprising a controller configured to acquire performance data indicating a usage record of a plurality of vehicles that travel along a predetermined route, predict, based on the acquired performance data, a ride demand during a time slot in which each vehicle is operated, determine to operate each vehicle as a regularly scheduled vehicle during the time slot in a case in which a resulting first predicted value of the ride demand is higher than a first threshold, determine to operate each vehicle as a non-scheduled vehicle, which is dispatched in response to an individual request from a user, during the time slot in a case in which the first predicted value is equal to or less than the first threshold, acquire status data indicating an existence status of at least one user when each vehicle is operated as a regularly scheduled vehicle during the time slot, predict a ride demand during a remaining time of the time slot based on the acquired status data, and determine to introduce an additional vehicle onto the route for the remaining time in a case in which a resulting second predicted value of the ride demand is higher than a second threshold.
