Optimization of disposition for terminal air defense system based on set-covering model

Proper dispostion of terminal air defense system (TADS) has a significant effect on air defense task fulfillment from the military and economic perspectives. In this paper, two dispostion concepts including fring range covering and firing angle covering are proposed, and the correspongding integer programming modeles are developed respectively to optimize dispostion solutions. The conclusion that dispostion solution obtained with firing angle concept is more effective than that obtaind with firing range concept is proved, and an example is given to illustrate the conclusion. The study in this paper is also applicable to the disposition of such weapons as anti-tank missiles and neutralizing guns.
