Influence of production specialisation level on efficiency of technical service and safety of buses operation
Abstract
Introduction. The focus is on improving the maintenance and repair system of city buses on the scale of large cities in particular and regions in general. Due to the increase in the number of rolling stock, the load on the existing technical service organisations increases, which in turn leads to their overload. Consequently, the efficiency and safety indicators of bus operation are reduced. The proposed solution is to develop a system of centralised specialised production.Materials and methods. The system of maintenance and repair is considered from the point of view of the marginal utility theory. Dependences of total and marginal utility on the quantity of goods (services) are presented. The term ‘specialization’ is described from the point of view of the motor transport industry. The necessity of combining universal and specialised posts is justified.Results. The results of the experimental study on ten passenger enterprises are presented. The results of calculations of the efficiency indicators of the current repair area are given. The dependence of annual costs and profit of the current repair zone of ten posts on the level of specialisation is reflected. The dependence of the coefficient of technical readiness of buses on the scale of parks in Russia is analysed. The natural factors, influencing the coefficient of technical readiness are presented. An adequate mathematical model with physical variables of the dependence of the coefficient of technical availability on the scale of the enterprise and the level of specialisation was obtained with further processing and verification of the results.Discussion and conclusions. The results of the study are intended for the enterprises of passenger transport. The data obtained will allow to develop a system of cooperation of technical service production facilities in order to improve the performance of requests for maintenance and repair of rolling stock.
