Command and control network cascade failure model construction method based on node importance

Abstract

The invention discloses a command and control network cascading failure model construction method based on node importance. The cascading failure resistance of a command and control network can be remarkably improved by reasonably adjusting corresponding parameters in a model, and the cascading destruction resistance of the command and control network is optimal due to the existence of optimal model parameters. According to the OODA combat theory and in combination with the concept of combat link betweenness, a new initial load definition method, a nonlinear load capacity model and a load redistribution strategy are given, and the internal mechanism and the external behavior of command and control network cascade failure can be reflected more effectively and accurately.

Description

technical field [0001] The invention belongs to the field of military command and control, and relates to the establishment of a command and control network cascade failure model, specifically a command and control network cascade failure model based on node importance. Background technique [0002] The command and control network, as the hub of command and control system order issuance and information transmission, is the key to victory in war. With the continuous improvement of battlefield informatization, the organizational structure of the command and control network is becoming more and more complex, and information interaction is more frequent, showing the characteristics of diverse and heterogeneous nodes and multiple interlaced links, which have typical complex network characteristics. At the same time, the command and control network is also the primary target of enemy attacks, and destroying the command and control network destroys the heart of the combat system. ...

Problems solved by technology

Although the cascading failure model of complex networks has made some achievements, its application in military command and control networks is still in its infancy

If the above cascading failure model is directly applied to the command and control network, there are mainly the following problems: First, there are a large number of edge nodes in the command and control network, and the degree value or betweenness value of these nodes is a fixed value, and the traditional method definition cannot distinguish the same important It is obviously not suitable for complex command and control networks with distinct loads

[0004] In view of the fact that the existing cascading failure model only considers the importance of the node itself and does not consider the contribution of neighboring nodes, it is difficult to directly apply it to the command and control network because of the low accuracy of the initial load definition and the impact on the cascading invulnerability of the network.
