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.
