Dependability measures assessment of electronic equipment according to field dependability test

Abstract

The paper considers dependability measures assessment method of electronic equipment during field dependability test. The idea of the method consists in monitoring and registration of observable parameters of events and states such as explicit failures rates, duration of states, frequencies of states. These parameters are estimated by experimental dependability assessment. Application of analytical-experimental dependability assessment allows you to obtain nonobservable parameters estimations such as latent failures rate and check-out errors probabilities of the first and the second kind. The considered approach is based on matrix dependability model for long functioning stochastic systems. Relations between parameters are derived by using this model.
