The research is focused on the modeling technology of cyber war system. A new idea is proposed for cyber war simulation, based on which an integrated logical evolving network model of cyber war system is proposed. The model regards all of the entities which belong to different forces as components of a whole system, and represents them with verticals of the network, all kinds of interactive behaviors between distinct entities which include the cooperative behaviors, parallel behaviors and confrontational behaviors are represented with edges of the network uniformly. An entity description model based on ontology and a behavior description model based on OO-LAMBDA language are built to describe the verticals and the edges respectively. Finally, a simulation experiment is conducted by using a scenario of a real operation, the results of the experiment validate that our methods are validity and advantage.
