Event oriented analysis of fail-safe objects

The paper tackles the issue of lifetime service uncertainty modeling of redundant engineering objects by event-oriented systems analysis. The objects involved acquire new functional states after configuration changes due to component failures and load redistribution. The article focuses on "oail-safe" object under random loads in order to reveal that the structural redundancy has to account for a number of events as well as for their probability distribution. The redundancy is assessed by employing the conditional entropy of the transition and residual strength. Moreover, it is demonstrated that the entropy of redundant objects is quantifiable and in case of transitive behavior always increases.
