The article considers a methodological approach to improving the calculation of the production program for technical maintenance and current repair of automobile rolling stock in the conditions of a motor transport enterprise. Given the diversity of modern cars in motor transport enterprises, it is proposed to use a cyclical method of calculating the production program to determine the volume of service work, which involves determining the optimal calculation cycle for performing routine service work for specific brands of cars.
A motor transport enterprise is represented by a complex structure, which includes such subsystems as: diagnostics and control; main production; auxiliary production; service production. Among them, the central place in the system of technical maintenance and current repair of vehicles is occupied by the main production, as a subsystem that performs service routine work and maintains vehicles in technically sound condition.
It has been established that the purpose of the maintenance and repair system is to ensure the required level of performance at minimal cost, which can be achieved by creating optimal capacities of subsystems for joint work and increasing their efficiency through organizational and other measures.
It was found that to ensure the required level of vehicle performance, it is necessary to calculate the throughput capacity of the main production subsystem of a motor transport enterprise using mathematical methods of the theory of mass service.
To assess the system throughput, together with the incoming flow of requirements, it is proposed to determine the duration of technical actions in the main production.
The article presents a mathematical model of the system of technical maintenance and current repair of automobiles based on the economic criterion of ensuring minimum costs or maximum specific profit.
The methodological approach to developing a working hypothesis is presented in the form of an objective function of minimizing the total costs of maintenance and current repairs of automotive rolling stock, which are performed through optimal calculated mileages – adjusted, recommended by automakers, inter-service mileages.
The purpose of the article is to clarify the indicators by which it is possible to further improve the calculation of the production program for technical maintenance and current repairs of automobile rolling stock in the conditions of a motor transport enterprise.
