ABSTRACT
A systems approach to network modeling and analysis has been recently proposed by the authors as an alternative to gain conceptual insight on systems’ structure and to reduce the computational cost of network reliability analysis. In such approach, a network system is recursively decomposed into subsystems and described hierarchically obtaining different models of the network in terms of the subunits that compose it at different scales. Then, models with different scope and precision are available depending upon the level of abstraction where analyses are performed.
