1. A service plan change assistance apparatus included in a train traffic management system, the service plan change assistance apparatus comprising:
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, an increment of a delayed time of the to-be-delayed train that is delayed due to the delayed train on a basis of a delayed time of the to-be-delayed train in a case where the delayed train is not delayed, 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
a processor coupled to a memory storing instructions, the processor executes:
train service simulation processing of estimating a future train service status based on a train service plan and a train service record before a current time;
delay increasing point identification processing of identifying, from the estimated train service status, the station at which the to-be-delayed train is delayed due to the delayed train; and
service plan change proposal creation processing of inputting an increment of a delayed time of the to-be-delayed train that is delayed due to the delayed train on the basis of a delayed time of the to-be-delayed train in the case where the delayed train is not delayed and 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 reducing a delay of the to-be-delayed train at the identified station, and outputting the created service plan change proposal, such that a route control apparatus of the train traffic management system controls a train by the service plan that reflects the created service plan change proposal that is outputted.
