REPAIRABLE SYSTEM RELIABILITY WITH HIDDEN FAILURE OF CONTROL DEVICES

Résumé

The aim of this paper is to describe how the reliability characteristics of a system living in a controlled environment with constant stress may be modified by taking into account of random failure of the control device. Such issue arise when reliability objectives have been demonstrated under stong assumption of constant environmental conditions, but some device that controls the environment (temperature, pressure, voltage, current intensity), may also be subject to failure. Standard results obtained by applying a cumulative damage model are introduced to provide updated predictive reliability characteristics (reliability function, mean time to failure) that mix reliability distributions of the principal component and the control device. An application on real data in the aeronautic field is proposed. The statistical analysis is also addressed and illustrated with simulated data under different observation and maintenance policies.
