Abstract. The article presents a solution to the problem of choosing the brand composition of truck tractors for the recruitment of transport divisions of oil pipeline enterprises. The main task of transport departments is to meet the needs of the main production. The equipment is operated under harsh conditions, as well as after the end of the regulatory period of use and needs to be updated quickly. Despite the timely maintenance and repair of freight rolling stock, frequent failures and increasing repair costs make further operation economically inefficient. When updating the fleet of vehicles, there is a problem in choosing the best in terms of the technical characteristics of the vehicle, but at the minimum cost. The purpose of the study is to optimize the costs of acquiring and operating special equipment of Transneft-Siberia JSC by developing a methodology for determining the rational grade composition of truck tractors. According to the a priori ranking method, the opinion of specialists and heads of transport divisions of Transneft-Siberia JSC was determined. For the study, the most popular brands of truck tractors of domestic and foreign production were chosen. As a result of the survey, the ranks of operational indicators of truck tractors and their weight are determined by the reverse ratio. The most signifi¬cant indicator as a result of a priori ranking is the cost of one unit of the vehicle. Integral coefficient components calculated relative to average value of each indicator are identified for each indicator. As a result of the study, it was revealed that for the renewal of the fleet of truck tractors, it is advisable to give preference mainly to foreign manufacturers. The integral factor, taking into account the weight of operational parameters, makes it possible to objectively evaluate the quality of truck tractors. The method of determining the integral coefficient is proposed, when using which it is possible to reduce the cost of acquiring and operating vehicles with an increase in the development of special equipment. Further areas of research are determination of integral factors for the fleet, including technological transport, as well as determination of the optimal nomenclature of special equipment for transport divisions of oil pipeline industry enterprises.
Key words: integral factor, process transport, truck tractor, operating factor, fleet structure.
