Abstract: The air force is one of the key elements in modern warfare and its main weapons are combat aircraft. Taking the campaign superiority parameter as objective function, a nonlinear programming for the combat aircraft weapon systems of air force was completed by using the complex method with constrains. The optimal collocation of the military airplanes under the limitations of equipping quantity and purchasing budget was worked out. An example indicates that the used mathematical models, method and arithmetic are correct and effective. It also shows that the established software system is quite practical and applicable. An explanation of the calculated results and evaluations for complex method and the software system were summed up in the conclusion.
