Fast work breakdown structure generation algorithm for aircraft assembly scheduling based on assembly order

To generate detailed assembly planning and improve fine control ability for assembly workshop, a generation algorithm of working structure decomposition based on assembly order was proposed on aircraft assembly scheduling. In the algorithm, a three-level assembly operation model was established according to the existing partition of work area and work station in workshop, which refined foundation for assembly field control. Through using information mapping rules between Work Breakdown Structure (WBS) and Assembly Order (AO), rapid integration of the assembly process information and the task information in workshop planning was realized. The WBS automatic generation method for outline task and node task were set up by assembly operation model and mapping rules. In addition, the implementation techniques and the application of the aircraft assembly field were introduced, and the result demonstrated the feasibility of the algorithm.
