三河门窗厂产线平衡的改善研究

Research on improving the line balance of Sanhe Doors and Windows Factory

为提高三河门窗厂生产线的平衡率,首先测量了内开扇的工时,根据流程程序图和工时表分析了内开扇制作过程中存在的原料、人员等的浪费现象,然后利用程序分析和人机操作分析等方法,提出了合理分配人员、改用部分原料、添加辅助工具等改善措施。改善的方案实施后,内开扇批量加工时间由17.15 min减少为10.99 min;产线平衡率由49.6%提高到85.3%,达到了良好状态。

In order to improve the rate of line balance of Sanhe Doors and Windows Factory,we measured the working hours of the Opening Fan.Based on the chart of the flow process and the table of the working hours,some problems such as waste of raw materials,staffs and so on in the opening fan processing have been solved out.Hence,the improved measurements have been taken to delegate the operators and allocate the personnel rationally,use raw materials and add auxiliary tools instead.With the improvement,the process time of the Opening Fan was reduced by 17.15 min to 10.99 min;the rate of line balance was increased 49.6% to 85.3%.The line balance achieved a good condition.
