基于价值流图析技术的剪叉高空车装配流程优化

The optimization of assembly process of scissors aerial vehicle based on the technique of value stream mapping analysis

针对SM公司剪叉高空车装配线存在的产能不足、生产流程混乱、人员利用率低和装配线平衡率低等问题,提出基于价值流图析技术的精益改进方案。根据公司生产现状绘制出GTJZ0608剪叉高空车现状价值流图,根据现状价值流图,分析出当前生产过程中存在的主要问题。通过应用均衡生产、拉动式生产,以及改变物料配送方式和生产作业控制等精益生产方法来优化生产流程,并绘制出未来价值流图。通过改进来优化产品的生产流程,缩短产品装配周期,减少库存和物料搬运距离,提高人员利用率和生产线平衡率。

Assembly line for scissors aerial vehicle of SM company cannot meet customer demands in quantity, the problem of production process chaos, low personnel utilization ration and low assembly line balancing ration need to be solved. Therefore, one improvement method based on the technique of value stream mapping analysis was proposed to work out the above problems. First- ly, according to the production status of the company ,the current value stream map of GTJZ0608 scissors aerial vehicle was drawn up. Then, the main problems existing in the current production process were analyzed according to the current value stream map. Finally, through the application of lean production methods such as leveling production, pull production, changing the way of material delivery and production operation control, the production process was optimized, and the future value stream map was created. After above improvements, the production process of the product was optimized. As a result, the product assembly cycle can be shortened, and then the inventory and material handling distance can he reduced, at the same time, the personnel utilization ration and assembly line balancing ration can also be improved.
