Establishment method of command network cascading failure model having hierarchical structure

Abstract

The invention relates to an establishment method of a command network cascading failure model having a hierarchical structure. The method concretely comprises the following steps: S1, defining the initial load and capacity of nodes in a command network; S2, using a command network failure node load redistribution method to update the loads of all the intact nodes in the network for once; S3, evaluating the cascading anti-destruction performance of the command network; S4, establishing the command network cascading failure model; S5, adjusting parameters in the model according to the established cascading failure model, using the provided cascading anti-destruction performance evaluation to estimate the anti-destruction performance of the command network, and enabling the cascading anti-destruction performance of the command network to be optimal. The method combines the hierarchical structure of the command network and takes the strict affiliation in the command network into account, thus being capable of better reflecting the internal mechanism and extrinsic behavior of command network cascading failure effectively and accurately.

Description

technical field [0001] The invention belongs to the field of military command and control, in particular to a method for constructing a command and control network cascading failure model with a hierarchical structure. Background technique [0002] With the continuous evolution of information warfare, the command and control network, as the nerve center of information warfare system and system confrontation, has not only become the key to our victory in the war, but also the primary target of the enemy's attack. In order to meet the needs of information-based operations, the command and control network connects all types of command and control nodes at all levels into a complex network that is vertically integrated and horizontally interconnected. The accusation network shows the characteristics of scale-free structure, hierarchical load distribution, and large difference in node importance. The complexity of the accusation network also increases the vulnerability of the net...

Problems solved by technology

[0004] In view of the fact that the existing network cascade failure model does not consider the characteristics of the hierarchical structure, it is difficult to effectively analyze the problem of the invulnerability of the accusation network, and the existing cascade failure model cannot be directly applied to the accusation network; therefore, this application proposes a accusation network with a hierarchical structure. A network cascading failure model construction method, which combines the hierarchical structure of the command and control network, and considers the strict affiliation relationship in the command and control network, can more effectively and accurately reflect the internal mechanism and external behavior of the command and control network cascading failure
