Embodiment Construction

[0040] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] A method for analyzing complex network vulnerability and resilience relationships, such as figure 1 As shown, the data in this embodiment is a simulation experiment based on the relationship network diagram of a certain club in the actual social network. The network contains 34 nodes and 78 edges. Specifically include the following steps:

[0042] Step 1: Construct an unweighted and undirected network with N nodes.

[0043] In the unrighted and undirected network system, each node represents an individual, and a network is formed by connecting edges between nodes, and each connecting edge represents the interaction relationship between connected individu...

Abstract

The invention provides a complex network vulnerability and elasticity relation analysis method, and relates to the technical field of information and control. According to the invention, after the relationship between the vulnerability and the elasticity is obtained, one more measurement standard is provided for the performance of the network. Existing research work does not indicate that the vulnerability of the network can be reduced by adding edges to the network, yet a method for reducing the vulnerability of the network is provided through the obtained relation between the vulnerability and the elasticity (edge adding enables the elasticity to be increased, and the vulnerability is reduced). Besides, enhancement of the network elasticity and reduction of the network vulnerability are good indexes for improving the network performance, and the improvement of the performance of the network elasticity and the network vulnerability can be realized by slightly changing the network (namely adding a small number of edges) through obtaining the relationship, which is a good discovery.

Description

technical field [0001] The invention relates to the technical field of information and control, in particular to an analysis method for the relationship between vulnerability and elasticity of complex networks. Background technique [0002] Complex systems often manifest as a dynamic interconnection of nodes and edges (i.e., networks), where the interaction patterns between different parts are inherently complex and may evolve with system dynamics. The vulnerability of a complex network is measured by its ability to maintain stable behavior after the edge weights and interconnection structure of the network are perturbed. The resilience of complex networks refers to the system-level self-adjustment ability that can guarantee basic functions and recover quickly from major disruptions when the network is disturbed. For ecosystems, vulnerability affects the possibility of coexistence among species, and resilience affects the possibility of stable equilibrium among species. In...
