“…We also note that these bounding methods also apply to the models by Hughes [6] that explain correlation between random failures in redundant hardware in terms of variation of failure rates with environmental stress. Variation of failure rates with environmental factors will typically be easier to assess than variation of difficulty between demands.…”

“…Common stresses (e.g. like elevated temperatures) or shocks are modeled as creating specific demand classes where hardware pfds are increased, but still failures are independent conditional on this higher pfd (possibly very close to 1, for shocks affecting hardware in both trains) [5].…”

“…This form of modeling has been used in earlier work [4][5][6] to model in a consistent way failures due both to physical causes and to design, and thus both hardware and software failures. The basic idea here is one of variation of the probability of system failure between different demands, as an explanation for dependence in failure behavior between diverse trains to be used in a fault tolerant system (e.g.…”

“…However, it has been keenly observed that human error and common-cause failure are very much influencing constraints in performance and/or reliability analysis of system repair problems. Few earlier research workers confined the reliability behavior of k-out of-n systems taking into account the common-cause failure, for example, Hughes (1987) presented a new approach to common-cause failure in analyzing system repair problems and Who Kee Chang (1987) attempted for reliability analysis of a repairable parallel system with standby involving human failure and common-cause failures yet no attention has been paid to the performance evaluation of k-out of-n repairable system due to human error and system failure constraints. Jain et al (2002) studied a k-out of-n system with dependent failure and standby support and Moustafa (1997) also studied k-out of-n repairable system with dependent failure and imperfect coverage.…”
