Statistical diagnostics of irreversible avionics as a controlled random process

Abstract

The general method of statistical diagnostics of irreversible avionics according to its actual condition, based on a martingale interpretation of the diagnostic process as a game with nature, is proposed. A general solution to the problem of determining the optimal moment of transition in statistical diagnostics is given. A design criterion since the switch to statistical diagnostics is made. The efficiency of the proposed methods for the timely detection of emerging and developing defects avionics according to the results of indirect measurements of controlled parameters is shown.

The prerequisites of forming a risk management system in the design of facilities space application

“…Then, the reliability (probability of failure-free operation) of the test piece for the i-th parameter is estimated by the formula Equation (1) gives a quantitative description of the significance of different sources of risk. In unit 15 the proposition about stopping control process or its continuation, based on the calculation and analysis of the trajectory of the functional loss and the terminal benefit, is decided [4]. If unit 15 detects the inadequate reliability of the statistical models of the some parameters, then the unit of mode setting 19 generates a signal to continue the monitoring process.…”
