Operation architecture plays a more important role in Network Centric Warfare (NCW), which involves dynamic operation networks with complex properties. Thus, it is essential to investigate the operation architecture under the informatization condition within NCW and find a proper network construction method to efficiently coordinate various functional modules on a particular situation, i.e., the aerial combat. A new method integrating the physical level and functional level of NCW is proposed to establish the operation architecture, where the concept of network operation constraints unit and net constructing mechanisms are employed to avoid conflicts among different platforms. Meanwhile, we conduct simulations to assess the effectiveness and feasibility of the constructed operation architecture and analyze the influence of the network parameters.
