This application provides a palletizing method, storage medium, and program product for air freight. By acquiring first information input by the user in natural language, the method directly identifies the user's intent to determine whether it is for palletizing. Upon successful identification, it automatically extracts key second information such as the target aircraft type, target pallet type, business priority, business attributes, and cargo dimensions and weight. Based on the extracted second information, it automatically determines the corresponding first palletizing scheme. Subsequently, based on the palletizing scheme, it uniformly generates and directly outputs a first task identifier, a first natural language summary, a first three-dimensional visualization model, and a first cargo loading list. This eliminates a large number of tedious operations such as manual information processing, manual scheme formulation, manual list organization, and manual result summarization, thereby effectively shortening the overall palletizing processing cycle and significantly improving palletizing efficiency.
