Abstract: Under the background of information and intelligent warfare, all kinds of support organizations at all levels interweave into a network structure, and the effective protection of important support nodes has become an important concern for improving the overall invulnerability of equipment support network. In view of that the node deletion method, the importance contribution method and the efficiency matrix method cannot effectively distinguish the node importance in the local scope, the membership function expression of nodes is constructed based on the fractal and similarity principle of complex networks, and the influences of different nodes at the shortest distance on the central node in a given radius are analyzed. The importance of nodes is described by using the fuzzy local dimension, and the specific algorithm is described in detail. The example shows that the proposed method can be used to quickly and accurately identify the important nodes in the equipment support network, and provide decision support for targeted implementation of node attack immunity.Key
