Review of the network risk propagation research

Abstract

The Network Risk Propagation (NRP) research, combined the theories of Complex Network and the risk propagation, has become one of the main directions in Complex Network study. Is this paper, we introduced the international mainstream research achievements, including the risk propagation threshold-network topology, the NRP-Cascading Failure model, the Immunity from danger in a network-Pinning Control theory. But, about risk source propagation threshold, risk distribution parameter in different networks, early Cascading Failure model and the interaction among different risk systems, are still needed to make forward in order to improve the knowledge about the NRP and reduce its possibility.

A novel methodology concentrating on risk propagation to conduct a risk analysis based on a directed complex network

“…Traditional risk analysis technologies are mainly conducted with the usage of easy‐to‐understand data (Cui et al., 2019). However, the internal dynamic characteristics of the risk propagation process are difficult to reveal at the data level.…”
