Carrier-based aircraft ammunition loading is an important part of carrier-based aircraft ammunition support,and traditional carrier-based aircraft ammunition loading scheduling usually ignores the constraints existing in the work.To solve this problem,the constraints in the ammunition loading work are analyzed,and the sum of the ammunition loading time of all carrier-based aircraft is taken as the optimization objective,and a model of carrier-based aircraft ammunition loading scheduling is established,which considers different initial loading time of the carrier-based aircraft and the ammunition loading space.An improved genetic algorithm based on chromosome segment coding is proposed,which avoids the generation of a large number of unfeasible solutions and improves the efficiency of the algorithm.Through simulation analysis,the feasibility of the ammunition loading scheduling scheme obtained by the model and the algorithm is verified.
