Reliability Analysis of C4ISR Systems Based on Goal-Oriented Methodology

Hard-and-software integrated systems such as command and control (C4ISR systems) are typical that comprised of both software hardware, the failures devices result from complicated common cause (or shared) signals make classical reliability analysis methods will be not applicable. To this end, paper applies Goal-Oriented (GO) methodology to detailed analyze a C4ISR system. The well failure probability system, reached based on GO model constructed. At component level, units system is computed. Importance completed by qualitative capability model, which critical hardware like communication module motherboard network application decompression ascertained. This method contributes all hard-and-software systems.
