Cascading Models

Generic cascading model

In order to assess cascading effects in directed network TUD/ETHZ has developed a model for the dynamics of failure spreading. The model combines network nodes as active, bistable elements and delayed interactions along directed links. By means of simulations TUD/ETHZ studied the dynamics behavior for generic sample networks.

Simple dynamic cascading model

In addition to the generic cascading model TUD/ETHZ has suggested a cascading model in networks using dynamical flow model based on simple conservation and distribution laws to investigate the impact of transient dynamics caused by rebalancing of loads after an initial network failure. The robustness of complex network showing cascading failures is determined by complex interplay between the network topology and flows dynamics.
