Problems solved by technology
The huge damage caused by natural disasters not only makes it easy to become an attack target, but also local faults can easily evolve and lead to the overall paralysis of the system. On the one hand, it may cause major economic losses, and on the other hand, it may even cause serious damage to related industries and national security. threatening, highly destructive

The present invention relates to a method and system for strengthening network elasticity of key infrastructure. The method includes: acquiring network parameters of a critical infrastructure network; the network parameters include a set of nodes and a set of edges; acquiring operational parameters of the critical infrastructure network at the current moment; the operational parameters include structural parameters and load data, and the structural parameters are the critical infrastructure network The load data includes the load value of each node in the critical infrastructure network; according to the operating parameters of the critical infrastructure network, determine the enhanced node identification ranking index of each node in the critical infrastructure network at the current moment; Multiple nodes with the highest ranking index are determined as nodes to be strengthened, and a set of nodes to be strengthened is obtained; each node to be strengthened in the set of nodes to be strengthened is strengthened in turn; the tolerance value of each node to be strengthened after strengthening is infinite. The present invention can improve the elasticity strengthening effect of the key infrastructure network.
Description
technical field [0001] The invention relates to the field of facility network strengthening, in particular to a method and system for strengthening network elasticity of key infrastructure. Background technique [0002] Critical infrastructure network is the "nerve center" of social economy and national defense security, as well as an important link of network security. It has a wide coverage and diversified functions. With the development of a new round of technological revolution and industrial revolution, critical infrastructure networks have effectively integrated and utilized existing resources by coupling the information domain and the physical domain, and the operating efficiency of different networks has also been greatly improved. However, with technological progress, we also face challenges brought by many uncertain factors. For example, due to the coupling effect, the network presents the characteristics of multi-network integration, the node scale is large, the s...
