Abstract: In answering the need of efficiency and intelligentization in aircraft assembly order planning, this paper pre-sents a data mining method for typical aircraft assembly order based on graph theory. The stop words lists and separator arrays are used as constraints to separate the assembly orders. A concept for Assembly Process Feature Vectors （APFVs） is presented to convey the separated assembly orders. The APFVs are mapped to Unidirectional and Sequential Chains （USCs）, and an Assembly Process Graph （APG） is constructed based on the USCs. An algorithm for the mining of typical assembly orders is proposed through defining the node support and edge support in the APG. The proposed method is validated by the assembly processed of horizontal tail, and the results suggest its feasibility with different support.
