Economic substantiation of calculation of the program of maintenance and current repair of vehicles (man)

Introduction Modern transport must meet the real conditions of the external environment (economic and technological) to ensure normal operation and growth in the market of transport services. Unfortunately, the technical base for the production of many vehicles today does not meet today's requirements. In addition, due to the obsolescence of development regulations and the inability to provide maintenance and repair programs for modern transports, the current repair costs have increased, so it is necessary to develop a scientific approach to this situation. The development of a program of maintenance and repair of modern cars requires the development of guidelines that meet modern requirements.

The task before us is to improve the methodology for calculating the maintenance and repair production program, the choice of vehicles based on the conditions of international transportation, to determine the specific cost of labor in the current repair work.

The object of the article is to improve the methodology for calculating the maintenance and current repair production program of a car service with high-resource rolling stock.

This article used the methods used to acquire new knowledge and evidence, discover new formulas, improve theory and develop practical recommendations, methods of collecting and processing scientific and practical data: observation, comparison, analysis.

The research method of selecting the solution of the selected specific problem requires a sequence of solving specific problems based on the conditions, requirements and limitations of the research. For example, the improvement of the calculation method of the maintenance and current repair production program determines the sequence: first the quantitative indicators (factors) are evaluated, then the qualitative indicators. These are a means of addressing the purpose of the study.

I used the literatures above to organize service work, perform technological calculations and identify modern trends in the subject.

There are special requirements for vehicles. The most important of them is environmental friendliness. Therefore, the article considers the least harmful to the environment.

In this literature, the operational characteristics of the process of transportation of vehicles by the method of calculation of the production program for maintenance and repair of rolling stock, are described in detail. The article reviews the truck service process using the literature mentioned above.

150 MAN will be put into practice by economically justifying the organization of maintenance of truck loads. The cost of the service is calculated and compared with the market price, the degree of competition is taken into account when creating a service program. the bank loan interest is charged on the funds required for the implementation of the project, the repayment period of which should not exceed the condition.Such an economic justification is made in the following sequence:

• 1.    Preliminary data on the organization of maintenance of 150 MAN trucks are given in Table 1.1.

• 2.    The main fund and production fund of the organization of maintenance of 150 MAN trucks is calculated.

• 3.    Calculation of the organization of maintenance of 150 MAN trucks, the annual volume of maintenance and the cost of preparation (per unit of service).

• 4.    A production program will be developed for the organization of maintenance of 4,150 MAN trucks.Revenue from it is cost, gross profit, depreciation and amortization.

• 5.    The payback period for the organization of maintenance of 150 MAN trucks.

• 6.    Indicators of the use of fixed assets: return on assets is the number of revolving funds, annual labor productivity, profitability.

• I.    Equipment, resources involved in the service process, their market prices and consumption norms (Table 1.1).

It was concluded that the project to organize the maintenance of 150 MAN trucks was based on today's market demand.

Conclusion To conclude, in order to conduct an experimental study to test the idea that it is possible to determine the program of maintenance and current repairs for existing mobile enterprises of foreign-made cars, in the case of implementing the full idea of maintenance, cars We take into account the mileage of the walk in the regulations of the full complex maintenance.

However, in each individual case, the impact of vehicle downtime on maintenance and its timing on the overall performance of the maintenance and maintenance production program can be seen in the calculations and tables above can be viewed.
