FORMALIZATION OF THE PROCESSES OF TECHNICAL OPERATION OF FREIGHT VEHICLES

Abstract

The operation of freight vehicles can be generally accepted as a comprehensive system of engineering, technical and organizational measures and can be considered in two interdependent areas. Firstly, ensuring the serviceable condition of freight vehicles (technical operation). Secondly, the efficient use of freight vehicles that are in good working order (production operation). In this case, operability means the property of freight vehicles in which the values of all parameters characterizing its ability to perform the specified functions meet the requirements of regulatory, technical and design documentation. In particular, technical operation involves the use of freight vehicles for their intended purpose. The aim of the study is to consider the formalization of the processes of technical operation of freight vehicles. It has been found that operational factors reduce the efficiency of freight vehicles and thereby affect changes in reliability indicators. As a result, there is a decrease in the productivity and capacity of freight transport, a decrease in the probability of its trouble-free operation and safety. That is, the technical condition and performance characteristics of freight vehicles depend on the degree of negative impact of operational factors on each of these systems. It is proved that freight vehicles are a complex technical system consisting of a number of functionally integrated systems. In order to ensure the reliability of freight vehicles during the service life established by the manufacturer, it is proposed to pay special attention to parallel and auxiliary systems during maintenance. At the same time, the frequency of maintenance of parallel-auxiliary systems should be added to the frequency of maintenance of series-auxiliary systems. Accordingly, the reliability and durability of a complex technical system will be determined by the quality of its operation.
