Abstract:

Aiming at the frequency planning and assigned problems of air-ground multi-variant complex networks, A frequency optimization model is proposed. Firstly, abstract the nodes and relationships in complex networks, the importance attributes of nodes are proposed from the aspects of role function, movement ability and network structure. Secondly, take each node as the basic object to make a decision, and the note’s property is deemed as a key element to influence the solution, then, a multi-criteria decision grey relation projection method is taken to calculate the closest between the solution and the ideal solution to obtain the importance sequence of the solution. Finally, the model’s effectiveness and rationality are confirmed according to the example of air-ground multi-variant frequency complex networks.
