1. A method for aircraft tooling modification, comprising:
generating, based on a modified design plan of a target aircraft, a tooling change order and a modified manufacturing bill of materials, including:
generating, based on the modified design plan of the target aircraft, an engineering change order and the modified manufacturing bill of materials;
evaluating, based on the engineering change order, a tooling of the target aircraft and generating a manufacturing change order; and
generating, based on the manufacturing change order, the tooling change order, wherein the modified design plan includes plans for a plurality of toolings, the tooling change order includes modification information for making modification to a technical condition of an existing tooling, and the modification information is obtained by analyzing and extracting information from the modified design plan of the target aircraft;
performing, based on an initial design plan for the target aircraft, a tooling design for the tooling to obtain a design model;
obtaining, based on the design model and a structural relationship of the tooling, a tooling bill of materials;
modifying, based on the tooling change order, the tooling bill of materials to obtain a modified tooling bill of materials, wherein the tooling bill of materials is generated based on the initial design plan for the target aircraft;
establishing an association relationship between the modified manufacturing bill of materials and the modified tooling bill of materials;
generating, based on the association relationship and the modified tooling bill of materials, a fabrication outline, including:
obtaining a tooling structure tree by listing a tooling top level node in the modified tooling bill of materials and a tooling node used under the tooling top level node; and
generating the fabrication outline based on an unfolded tooling structure tree and the association relationship; and
obtaining a modified tooling based on the fabrication outline.
