Abstract: Aiming at the problems of low personnel utilization,in-process inventory and long product production cycle in DC company's drive shaft assembly line,an assembly flow optimization scheme based on value flow graph technology was proposed.According to the production status of company,the current value map of Φ57 ear hole series drive shaft's assembly line was analyzed,and discover the problems existing in the current production process was discovered.By combining the lean production idea,the improvement scheme was proposed in the aspect of balancing the production line,pulling the production and changing the material distribution mode.The simulation scheme of the proposed improvement scheme was simulated by FlexSim software,and the feasibility of the scheme was verified.The practical application showed that using value flow graph analysis technology can help to quickly find problems in production,shorten production cycle,improve staff utilization and achieve lean production.
