Study on production dffciency improvement of U-shaped assembly line based on IE idea

应用仿真分析以及工业工程方法对有合作的自由节拍装配线生产效率进行了改善研究。对装配线的运作现状进行了仿真,从平衡率和产量两个角度,分析了装配线运作中存在的不足以及成因;在上述分析的基础上,对工人的合作策略进行了局部调整,对瓶颈工位进行了作业测定,针对作业中存在的问题,通过方法研究对作业方法进行改善,并再次通过作业测定验证作业方法改善的效果;通过仿真验证了装配线生产效率改善措施的总体效果。研究表明:通过合作策略以及瓶颈工位作业方法的改善,能够以较小的代价提高装配线的生产效率。

The production efficiency of cooperative paced assembly line was improved through simulation analysis and industrial engineering methods.The operation status of assembly line was simulated,and the shortcomings and causes in assembly line operation were analyzed from the perspective of balance rate and output.On the basis of above analysis,the cooperation strategy of workers was partly adjusted,and the work measurement was proceeded with the bottleneck workstation.The working methods were improved according to the measurement results,and the improvement effect of working methods was validated by the work measurement again.The overall effect of production efficiency improvement measures of this assembly line was verified by simulation.The results show that through the improvement of cooperation strategy and working methods in bottleneck station,the production efficiency of assembly line can be im proved at a lower cost.
