The optimality criterion is the difference between the income and the costs and is the function of the frequency of certain operations on each of the car units. An algorithm has been developed that allows for the effective optimization of the processes of operating, repairing, and writing-off the cars, ensuring an increase in the competitiveness of rail transport due to the rational use of resources and optimization (reduction) of costs.
