Abstract:

Considering the complex multi-dimensional relationship of equipment in the equipment system, this paper constructs a spatialstructure network that reflects the spatialrelationship between equipment and a functional structure network that reflects the command and controland collaborationof 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 arevalidated throughthe example analysis ofa synthetic battalion executing offensive operation tasks.

Key words: complex networks, bi-layer coupling, equipment system, node importance, evaluation method
