Abstract:
According to the present invention, a controller: configures a first digital twin model which belongs to a railway system and simulates a subject to be value-improved; adjusts parameters of the first digital twin model by fetching operation data of the subject; configures a second digital twin model which simulates a subject to be updated when the value of the subject is improved by improving the accuracy of the first digital twin model; and enables evaluation for value improvement by comparing the simulation results when the first digital twin model and the second digital twin model operate under the same condition. Therefore, a railway upcycle system is provided which can improve the performance of an upcycle target, such as a facility or software related to the railway system, over that of existing specifications by accurately determining whether upcycling is right, and in addition, repetitively execute this performance improvement.
