In order to effectively carry through the arrangement of air-defense operation, insure important targets impunity or avoid losses, the distance question is researched between the anti-aircraft destroyer and the warned ship. From the view point of the whole information as a starting point, the model of formation anti-aircraft destroyer disposition is established, and taking example progress solve and simulation. The result shows that the model can offer theory reference for commander. By way of simulation analysis, some suggestions are proposed for area anti-aircraft destroyer disposition.
