Evaluation of Equipment Node Importance based on Bi-Layer Coupling Complex Networks

Considering the complex multi-dimensional relationship of equipment in the equipment system, this paper constructs a spatial structure network that reflects the spatial relationship between equipment and a functional structure network that reflects the command and control and collaboration of equipment. Based on this, a bi-layer coupled complex network model is put forward. Combined with the relevant characteristics of equipment architecture, the structural characteristics of each network and evaluation parameters of the node importance are determined, and coupled intensity is confirmed by the improved group analytic hierarchy process. The evaluation method of equipment node importance is determined. Finally, the rationality and effectuality of this method are validated through the example analysis of a synthetic battalion executing offensive operation tasks.
