Abstract

The article provides a calculation of the economic feasibility of introducing computer diagnostics of rolling stock in-house for motor vehicle enterprises engaged in international freight transportation. Based on the research, it was determined at what amount of rolling stock a positive economic effect occurs already 108 after two years of using the diagnostic equipment. All components of the cost of work at the motor transport enterprise and the cost of work at the cooperative were taken into account. The object of the study is the maintenance organization system at a motor transport company that carries out international cargo transportation. The purpose of the work is to determine the feasibility of introducing computer diagnostics at a motor vehicle enterprise, to select control parameters that make it possible to monitor the pre-failure state of car components and to predict repair or replacement of parts to eliminate accidental failures. Research methods – analysis of the work of enterprises in the industry that carry out freight transportation and use diagnostic equipment. Most of the motor transport companies carrying out cargo transportation have a small number of rolling stock. However, this is not an obstacle to the organization of computer diagnostics on one's own. Most of the cars have a service life of nodes close to the limit level and are in a predictable condition. It is advisable to carry out diagnostics of used trucks after each trip. Specialized service stations have all the necessary production bases, but in many cases, they are far from the motor vehicle enterprise. Economically appropriate delivery distances should be taken into account when servicing cars at car service enterprises in modern conditions. The second important factor is the frequent delay in the queue for service. Which inevitably leads to the loss of a truck's working day. A methodology for determining the economic feasibility of using diagnostic equipment at the enterprise has been developed. The number of rolling stock units at which it is expedient to implement this type of work by own forces has been determined
