The influence of the software, and its interaction and interdependency with the hardware in the creation and propagation of hardware failures, are usually neglected in reliability analyses of safety critical systems. The software operation is responsible for the usage of semiconductor devices along the system lifetime. This usage consists of voltage changes and current flows that steadily degrade...
This paper describes in brief the Reliability and Maintainability (R&M) Programs performed directly by the reliability branch at Goddard Space Flight Center (GSFC). The mission assurance requirements flow down is explained. GSFC practices for PRA, reliability prediction/fault tree analysis/reliability block diagram, FMEA, part stress and derating analysis, worst case analysis, trend analysis,...
