MATHEMATICAL SIMULATION FOR RELIABILITY PREDICTION

Abstract

The results of a study for the development of techniques for predicting the reliability of electronic systems from statistical information about the performance of system components are presented. The problem of determining initial system performance and system performance over time, given changes in component characteristics in time, is analyzed. The prediction of the reliability of systems whose performance is measured on a continuous scale and which are subjected to degradation type failures is emphasized. Catastrophic failure models including repair and redundant elements are also discussed. It is concluded that, with the exception of certain simple systems, mathematical simulation provides the only feasible means for generating the probability distribution of various appropriate measures of system reliability when component and system performance measures have a continuous range. The mathematical simulation technique is applied to several demonstration problems and information on the sample sizes required to estimate the distributions of reliability measures are given.
