基于精益生产的某民营企业继电器生产线改善研究

Improvement of Relay Production Line of A Private Enterprise Based on Lean Production

以某民营企业JZX-22F系列继电器生产线为研究对象,针对现场调查发现的库存堆积多、生产周期长、物料配送紊乱等问题,运用工作抽样法明确了生产线的库存状况及其产生原因.通过减少生产线的料盒数量、制定标准作业三票、降低转运批量等方法进行生产线改善.结果显示,生产线的在制品库存与完工检成品库存均减少了一半以上,精益生产对于继电器生产线改善有很好的实用价值.

This paper takes JZX-22F series relay produc- tion line of a private enterprise as the research object, to solve the problems such as multi-inventory, long production cycle and disorder material distribution etc. In this paper, the problem of inventory accumulation is analyzed by using work sampling method, and the improvements are taken by reducing the number of material box, developing standard operating three votes and reducing transport batch etc. The results show that the in-process inventories and completion inspection product inventories are reduced by more than a half and this suggests that lean production is a good practical tool for the improvement of relay production line.
