Abstract
The paper presents an approach to building digital twins of business processes for energy supply of train traction at railway ranges. The approach is based on a matrix structure for representing the business processes of freight transportation and their provision by the central directorates of Russian Railways. It is proposed to use functionals as a form of constructing digital twins (models), and as parameters of the digital model are indicators that have the highest level of correlation with the actual indicator of energy supply for train traction. The following indicators of business processes were considered as electricity consumption for traction of trains; specific energy consumption for traction of trains; power imbalance; work in electric traction; local speed; average weight of a freight train and others.
