The article proposes a methodology for assessing the effectiveness of robotic vehicles' functioning in terms of operation and maintenance. It is suggested to use the method of Data Envelopment Analysis based on fractional rational programming models. The parameters of robotic vehicles have been determined, for which a comparative assessment is carried out. The leading indicators of the maintenance and repair system efficiency are the downtime ratio for maintenance, the vehicle drift rate from the line, the reliability of the vehicle aggregates, robotic vehicle residual life, mileage per month, and the operation and maintenance unit cost. The basic models are the Cooper Charnes Rhodes and Bunker Charnes Cooper models using the super-efficiency frontier's construction. The analysis of solutions for various subsets of parameters of robotic vehicles is carried out. The production possibility set diagrams are plotted, and target changes in vehicles' parameters and the maintenance system are determined to achieve the efficiency frontier. The development of the maintenance system was assessed using the Malmquist index, and the reasons for the unsatisfactory operation of robotic vehicles were identified. Conclusions are made to improve the organization of the maintenance system.</p>system analysisefficiencymaintenance of vehiclesunmanned vehiclesData Envelopment AnalysisMalmquist indexсистемный анализэффективностьтехническое обслуживание транспортных средствбеспилотные автомобилианализ среды функционированияиндекс Малмквиста[Khaitan S.K, McCalley J.D.
