A ship surface support scheduling optimization method based on sliding time window strategy is proposed to address the problem of inadequate scheduling of carrier-based aircraft support operations in complex tasks of amphibious assault ships. An analysis was conducted on the characteristics of the shipborne aircraft surface support operation and the carrier deck operation environment, and a corresponding scheduling model was established with the goal of optimizing the support operation cycle. Based on the model characteristics, an improved greedy algorithm based on sliding time window strategy was proposed for solution; Later, by dividing the overall time of the support operation into several fixed time windows and using greedy algorithms to solve the optimal scheduling plan within each time window, it supports carrier-based aircraft to efficiently execute delivery tasks according to wave times. Simulate and validate the above method using a scenario study of amphibious delivery operations. The simulation results show that this scheduling method has good feasibility and superiority.
