There are still many manual processing procedures, and these procedures have not been digitally controlled. They mainly rely on manual methods and cannot meet the requirements of production efficiency and manufacturing quality. The production tasks in the composite material workshop have the characteristics of "parallel processing of multiple processes". The materials, processing hours, and processing contents used in each process vary greatly. There are situations where a large number of different process tasks of a composite part are processed simultaneously, involving the logistics transfer of different sections of the part and the simultaneous parallel logistics of multiple different types of parts.

[0003] At present, there are still many problems in the production control of the aviation composite material workshop.
