In order to increase the efficiency of the operation of motor transport enterprises, the structure of production units for maintenance and repair of cars should be determined by the scope of work, taking into account the cost of implementation of the unit labor complexity of works. In case of inappropriateness of creating or maintaining an MTE of separate production units, maintenance and repairs of cars should be carried out at specialized service centers. Therefore, with the improvement of production units of motor transport enterprises structure, it is important to provide economically expedient delivery distances for maintenance works and repair of cars by co-operation in car service companies, which provide relevant services. The determination method of economically expedient distances of cars delivery and repair fund for car service companies is given. The cost of cars delivery and repair fund for 1 km to the car service companies or other motor transport enterprises (MTE), which accounts for 1 man-hour of labor-intensive maintenance and repair is determined. The economically expedient delivery distances for maintenance and cars repair by cooperation in car service companies are determined. The results of the calculations show that for taxi-driven MTE economically appropriate in modern conditions of distance of delivery of cars to perform maintenance-1 and maintenance-2 are close to those recommended in literary sources. For truck and bus MTE the corresponding delivery distances for maintenance-1, maintenance-2 performance, ongoing repairs are significantly lower. When performing diagnostic works D-1 and D-2, most of the the district works of the ongoing repair, the economically reasonable distances of delivery to the car service companies are obtained that substantially exceed the recommendations given in the scientific literature.
