Substantiation of Probability Characteristics for Efficiency Analysis in the Process of Radio Equipment Diagnostics

The paper discusses the problem of statistical characteristics substantiation during radio equipment diagnostics. To provide serviceability and maintainability of radio equipment is one of the tasks of operation system. The operation system contains the processes of intended use of equipment, maintenance, running repair, continuation of life service and others. During running repair, the procedures of diagnostics, operability recovery and parameters monitoring are performed. The diagnostics process regulates the sequence of searching the failed element in the radio equipment scheme. The decision-making during diagnostics is associated with the errors of the first and second kind. So for efficiency analysis, the probability of correct diagnostics can be used. Such efficiency measure has random nature, but in the literature, only expected value is used to describe it. This paper concentrates on the approach to calculation of the probability density function for efficiency measure with purpose of obtaining the complete information about random value.
