Abstract
Provided is a service plan change assistance apparatus () including: a storage apparatus () that stores a decision model in which a service status of each of a delayed train and a to-be-delayed train to be delayed due to the delayed train and train service plan change content for recovering a delay of the to-be-delayed train are associated with each other, in association with a station at which the to-be-delayed train is delayed due to the delayed train; and an arithmetic apparatus () that estimates a future train service status based on a train service plan and a train service record before a current time, identifies, from the estimated train service status, the station at which the to-be-delayed train to be delayed due to the delayed train is standing, inputs information on the estimated train service status to a decision model associated with the identified station to create a service plan change proposal that includes information indicating train service change content for recovering the delay of the to-be-delayed train, and outputs the created service plan change proposal.
