Digitalisation of the Database of Passenger Coach’s Elements Using the Example of Wheelset Repair

Meeting the needs for transporting passengers while ensuring the appropriate level of comfort and safety are always paramount when repairing rolling stock. The creation of automated systems to support repair and maintenance works allows systemising the repair process itself and clear and timely planning of material and production resources. Digitalisation of the production process makes it possible to achieve a coherent functionality and to link production and economic indicators together to ensure a balanced load on the repair bay, and subsequently on the entire enterprise, while development of a single digital system allows one to unlock the potential for improving the technological base. Development of software and hardware system of «digital» repair of a wheelset is studied with object-oriented and heuristic methods The study’s subject refers to technological operations and production processes of reception and repair of a passenger coach’s wheelset. The object of the study is the process of organisation of the repair of rolling stock components at the operational stage of the life cycle. The study describes main characteristics of organisation of repair of a passenger coach’s wheelset from its reception for maintenance and defect detection to release into operation after current, medium or, respectively, major repairs. Particular attention is paid to the processes of interaction between managers and performers at each stage of repair. The novelty of the research is regarded through the application of a system approach to the use of digital technology in the production process to obtain analytical data and generate economic and production indicators. The main conclusions tend to substantiate creation of a hardware and software system of a «digital twin» of a passenger coach’s wheelset repair bay
