Optimization of a Multi-node System Reliability Model

In order to improve the reliability of an electronic or a computer system,redundant components always need to be added as part of the system.When an active component fails,a standby component will be activated to guarantee the system in operation continuously.The standby component and the switching device have been usually assumed to be continuously functional during the setup of the reliability model.In fact,it is these two assumptions that induce deviations during modeling and introduce variances for the system reliability design.Through modeling and optimizing the dependability of the synchronous clock system that decomposed from a multi-node system,a new reliability model which takes these two elements into consideration has been developed.Simulation results demonstrate that the upgraded reliability model is closer to the actual dependability of the real system.The capability of the system reliability design is also improved as a result.
