"DIGITAL twin" TECHNOLOGY IN LOCOMOTIVE MAINTENANCE
"Digital Twin" is one of the basic directions of economy and industrial enterprises digitization. The article considers a variant of "Digital Twin" technology application in automated locomotives maintenance and repair. It is proposed to use a self-tuning statistical model of the repair process to predict the time of the locomotive for the train after repair. According to the data of the onboard microprocessor control systems of the locomotive and stationary systems of technical diagnostics, it is proposed to form an individual repair schedule for the locomotive from elements, for each of which there are statistical data on their duration. According to the readiness of the schedule, the repair process is simulated according to the developed Digital Twin program and the expected time of locomotive delivery is calculated with the recommendation of the locomotive's garter time for the train.
