Review article

The article considers the tasks of substantiating the parameters of the production and technical bases of automobile enterprises in the conditions of using maintenance systems with individual correction of the service interval. It is shown that the use of traditional methods of technological calculation in this case can lead to a decrease in the efficiency of rolling stock operation by reliability criteria and, as a consequence, to a decrease in economic efficiency. The authors propose to consider maintenance requests from the fleet of vehicles as a stream of requirements corresponding to the «patterns of the third type». Based on this, a technique is proposed that allows calculating the maintenance program in systems with individual correction of the service interval, including with a given probability of execution. The study conclusions are confirmed by the analysis of statistical data of a really existing enterprise.
