In order to solve the problem of tradition operational method difficult to realize carrier-based aircraft ammunition scheduling, put forward carrier-based aircraft ammunition scheduling method based on genetic algorithms. Analysis the scheduling phases and mounting phases of carrier-based aircraft ammunition, the model of carrying-out schedule is set up and quantified with method of grade setting, and operators of genetic algorithms are adjusted to adapt to algorithm solving. Simulation result shows that adjusted algorithm operates stably, converges quickly, and sequence of ammunition scheduling harmonizes tow phases of support effectively, ensures the continuity of ammunition installing, and the efficiency is improved.
