Abstract:

The engineering support system plays an important role in supplying support resources for modern warfare. The ability of the system will be seriously affected due to the failure of critical nodes. Therefore, it is of great significance for future wars to analyze critical node identification technology in the equipment support system and identify the weak links. Based on the theory of complex networks, this paper proposes a comprehensive index to measure the importance of support nodes. On the one hand, the node importance index measures the connection ability of the support node in a certain spatial range. On the other hand, according to a task-oriented routing method proposed in this paper, the global transportation ability of the support node is measured. By comparing with six other node importance indexes, the result verifies the effectiveness and applicability of the node importance index proposed in this paper in identifying critical nodes.

Key words: equipment guarantee system, critical node, complex network, support ability
