Condition analysis of existing technological process for repair of electric traction motors of direct current freight locomotives with the use of theory of network planning and control

The paper provides information about the experience of using network schedules in the conditions of service locomotive depots that contribute to the observance of logical discipline in planning, drawing up calendar plans and managing repair work to restore traction engines of 2ES6 series of freight electric locomotives, as well as a set of measures to optimize the technological process of traction engines repair in the volume of TR-600. The analysis of the existing technological process of repair of traction engines allowed to reveal features of distribution of time of each operation in branches of the network schedule with identification of time parameters of volumes of repair of its separate nodes, and also to justify reserves allowing to accelerate carrying out planned repairs of traction engines in volume of TR-600 of the electric locomotive. The results obtained can be used in service locomotive depots when justifying measures to optimize the technological process of repair of electric locomotives in order to reduce the time and economic costs of repairing electric locomotives 2ES6.
