Sensitivity and uncertainty analysis in performability modelling

The authors present an exact Taylor series model of steady state performability measures and discuss the validity region of this approximation. They also describe an uncertainty analysis approach based on Monte Carlo simulation, apply both approaches to a performability mode, and discuss their relative merits. They vary the dependencies between model parameters and discuss their influence. For the case studies done, the sensitivity analysis overestimated the mean performability and underestimated its variance.<
