Abstract. The work is devoted to systematic substantiation of productivity, production structure and specialization of service station (SS) of KhTZ-3522 tractors. Based on the technical and economic comparative analysis of the results of modeling of the technological processes (TPs) of the second and third line maintenance, third line maintenance before current repair (BCR) and line maintenance before major repair (BMR) of KhTZ-3522 tractors, the parametrical series of production structures of service stations (SSs) both mono- and poly technological specialization, which can work effectively in a wide range of the general annual program of orders, and in the conditions of seasonal fluctuations of orders for the maintenance of these tractors, are founded. The results of calculations of the system of indicators of organizational and technological compatibility (OTC) of TPs of the second and third line maintenance, third line maintenance BCR and third line maintenance BMR of KhTZ-3522 tractors in the joint technological flow are presented. The dependencies of these indicators on the total annual program of orders for service stations of different productivity are analyzed. According to the results of the analysis, the poly technological specialization of such service stations is substantiated.
Key words: KhTZ-3522 tractors, maintenance, technological processes, organizational and technological compatibility, service stations, specialization.
