Improving the frequency of maintenance and repair of complex technical systems and products is always relevant, since it is based on calendar periods or mileage standards, which are founded, as a rule, on average analytical data. The principle of maintenance and repair system in long-distance passenger traffic is similar to the principles that apply to many sets of railway equipment, and is based on preventive technological operations when each unit of rolling stock reaches a specified period or mileage. These criteria make it possible to ensure the operation of passenger cars with high reliability. At the same time, cars, like any other complex technical systems, are improved and equipped with new, upgraded or more reliable elements and assemblies. Therefore, the issue of conducting maintenance and repair system should also be analyzed systematically, and new approaches to its organization, implementation and frequency of maintenance and repair should be proposed. The aim of the paper is to optimize the maintenance and repair system of passenger cars based on an assessment of their use over the entire life cycle period in terms of profitability of sales using the gradient descent method.
