The authors present an approach aimed at modeling and evaluating the reliability and availability of systems from the knowledge of the reliability growth of their components. First system behavior is characterized with respect to reliability and availability. The hyperexponential model for reliability and availability growth modeling is introduced and applied to multicomponent systems. The possibility of accounting for future reliability growth when performing evaluations during the design of the system is considered.
