Abstract
The article offered for complex technical railway, periodic maintenance required large economic costs, method of determining the optimal frequency of maintenance equipment with minimum cost. The calculation adopted by the portion of operating costs, which comes to preventive maintenance during maintenance and troubleshooting between maintenance. The cost of maintenance provided analytical dependence by performing maintenance, the cost per element is replaced and the number of items that are replaced during the period between maintenance. In turn, the time to perform maintenance as expressed through time for maintenance provided equipment uptime, multiplied by the appropriate exponential function. Thus obtained value maintenance. Under the scheme proposed analytical expression for the cost of removal of failures between maintenance. For expression failure flow parameter used by Laplace function. After finding these components resulting expression for the maintenance of absolute value, and then - for its specific value. The minimum value of this function will match the optimum size of the period between maintenance.
