Due to low efficiency problem in air defense weapon coordinate operations, an improved method of CNP was presented. According to reality of air defense operation, the system structure of air defense weapon coordinate operations decision-making based on MAS was established, proposed air defense weapon coordinate operations strategy based on MAS. Combined background of point air defense, a simulation platform named NetLogo was applied to verify and analyze the model. The simulation result shows that the improved model can effectively reduce communication load, reduce the weapon system response time and increase efficiency of air defense weapon coordinate operations.
