Target selection of smoke screen support is the basic premise of effective implemenation of smoke screen support. Through using the analytic hierarchy process (AHP), relevant factors of support target are determined by comprehensive considera? tion. On the basis of this, a scientific reasonable mathematic model is built, and finally the priority order of smoke screen support target is obtained. This result can provide reference for organizing and implementing smoke screen support, and realize the optimiza? tion and maximization of smoke screen support efficiency.
