Means of warfare and using of the military force are always changing as technology changes. Learning from the idea of NCW, it explored the formation mechanism of the operation network, and analyzed the combat behavior of micro and macro mechanisms. Aiming at the feature of obtaining the operational effectiveness through the information superiority，it proposed the conception of the control loop and the action rhythm in the information age, which reflected the different capability of using information between the combat systems. Thus, it proposed the combat model of operational network, and the performance indicators of measuring the operational network. It designed the experiments to study the engagement process and results of the different network structures, the different attack patterns.
