ECONOMIC AND TECHNOLOGICAL ASPECTS OF FORMATION THE OPTIMAL PARK OF LOCOMOTIVES IN CRISIS CONDITIONS
The article is devoted to the problems of updating the fleet of locomotives in current crisis conditions. The concept of "optimal locomotive" and "optimal fleet of locomotives" are formulated. The factors affecting the formation of locomotives’ fleet are systematized and analyzed. An approach to the formation of optimal fleet of locomotives, based on the constructional, functional, repair, and operational aspects, is proposed. The characteristics of the optimal fleet of locomotives are developed. Technological and economic parameters for estimation the optimal locomotive are proposed.
