Aiming at the demand for timelines, effectiveness and retroactivity in the complex product assembly, this paper puts forward a kind of barcode-based material flow control technology. This technology regards the idea of complete kit as guide which, on one hand, puts forward a closed loop control mechanism including rapidly kitting pallet preparation, field scan confirmation and retrospective statistical distribution service-oriented material flow control. On the other hand, this paper puts forward a material complete kit which forms a complete set technology of assembly planning driven. This paper realized the dispatch of correct material in the correct time and in the correct way. This paper forms a process-oriented material trace statistics technology and solves the classification statistical issues of material status and location. Finally, this paper develops a prototype system and then the effectiveness of the technology was verified.
