Abstract
When reliability requirements at the stage of developing complex technical systems are setting, the total number of individual and complex reliability indicators set in accordance with regulatory documents is within 5-7 units. This is done provided that they are recoverable, and also for them the requirements for durability and preservation are determined. All this determines the complexity of the procedure for their verification, confirmation and evaluation.
 Aim: Formation of a common (integral) indicator of reliability, which can characterize the basic reliability properties multitude of traction electrical equipment, as a complex technical system, subject to the compliance of individual indicators with the requirements specified in the terms of reference.
 Methods: It is proposed to use of T. Saati's hierarchy analysis method, which is widely used in solving various multicriteria problems.
 Conclusion: Using an integral indicator to determine the level of reliability allows getting a formalized result, expressed through the vectors of global priorities corresponding value, which makes it possible to get a quantitative assessment of the superiority for one of alternative traction electrical equipment.

При задании требований по надежности на стадии разработки сложных технических систем, если они являются восстанавливаемыми, а также для них определены требования к долговечности и сохраняемости, общее количество, задаваемых в соответствии с нормативными документами, единичных и комплексных показателей надежности находится в пределах 5–7 единиц, что определяет сложность процедуры их проверки, подтверждения и оценки

Summary
Цель: Формирование единого (интегрального) показателя надежности, который характеризовал бы всю совокупность основных свойств надежности тягового электрооборудования, как сложной технической системы, при условии соответствия отдельных показателей требованиям, указанным в техническом задании. Заключение: Использование для определения уровня надежности интегрального показателя позволяет получить формализованный результат, выражаемый через соответствующее значение вектора глобальных приоритетов и дающий возможность количественной оценки превосходства в плане надежности одного альтернативного варианта тягового электрооборудования над другим. With regulatory documents is within 5-7 units This is done provided that they are recoverable, and for them the requirements for durability and preservation are determined.
