Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation.

[0042] The present invention proposes a more comprehensive parameter for measuring the importance of nodes. The proposed parameters comprehensively consider the local and global characteristics of the node itself, as well as the influence of surrounding neighbor nodes when measuring the importance of nodes. In addition, the influence of mission requirements in equipment support is further combined, so that the proposed parameters can accurately identify key nodes under different mission requirements. Finally, by comparing with the other five node importance parameters that are often used to identify key nodes, a variety of task requirements are simulated, and from two aspects of identifying multiple and single key nodes, the proposed node importance parameters are evaluated in identifying equipment. Guarantee the performance of key nodes in...

Abstract

The invention discloses an equipment support system key damaged node identification method based on a complex network. Comprising the following steps: constructing a double-layer coupling network model according to characteristics of an equipment support system, and determining a time cost matrix, an economic cost matrix and an adjacent matrix of the double-layer coupling network model; performing lowest-cost path planning on each node pair in the double-layer coupling network model according to a mode of lowest total transportation cost, and calculating according to the lowest-cost path of each node pair to obtain improved betweenness centrality of each node; calculating the improved degree centrality of each node according to the adjacent matrix of the double-layer coupling network model; and according to the improved betweenness centrality and degree centrality of each node, the final centrality of each node is calculated and obtained, and then each node is sorted, so that the key node in the equipment support system is determined. The method is more effective than the other five common centrality parameters in the aspect of identifying a plurality of key nodes and a single key node.

Description

technical field [0001] The invention relates to a method for identifying key damaged nodes of an equipment support system, in particular to a method for identifying key damaged nodes of an equipment support system based on a complex network. Background technique [0002] With the continuous development of information technology, modern warfare has gradually evolved into informationized warfare, and various high-tech weapons and equipment have increasingly become the key to restricting the development of combat effectiveness. To give full play to the combat capabilities of existing equipment, it is necessary to establish a matching equipment support system to achieve precise support. While the equipment support system shoulders important support tasks during the war, it has gradually become an important target for the enemy to attack. Especially in the face of informationized battlefields, the enemy's precise strikes on our military's logistics support network have made the ...
