工作研究在流水线平整中的应用

Application of the Work Study to Balancing Production Lines

以某企业激光头基座准备(又称H S准备)生产线为研究对象,运用模特法及秒表测时法测定了流水线各工位的作业时间,找出了影响流水线生产能力的瓶颈工位和能力过剩工位;运用“5W1H”提问技术,分析流水线在设备能力、定员、任务分配、工艺内容及流水线布局等方面存在的问题;根据ECRS(取消、合并、重排、简化)原则及流水线平整理论设计了流水线平整方案,包括对现有设备的改进、相关工位作业内容的重新分配、调整部分工位的设备和人员、减少个别工位的机器作业时间、对生产线重新布局及实行分段管理等。新方案的实施使生产线生产能力提高61.4%,定员减少111人,年人工成本降低92.24万元,生产现场的环境得到了较大改善。

Aiming at laser head base preparation (namely H-S preparation) production lines of an enterprise, this paper applies the nodular method and second watch measuring time method to measure the work time of various stations of production lines, and to find out both the bottle-neck stations and the superfluous capability stations effecting on the line production capability. Problems of equipment capability、manpower、task distribution、technology and production lines layout are revealed and analyzed by using the 5W1H check list. Basing on the principle of ECRS (Eliminate, Combine, Rearrange, Simple) and the line balancing theory, this paper provides the line balancing schema, including the improvement of the existing equipment, the reallocation of the work content for relative stations, the adjustment of the equipment and workers of some stations, the reduction of machine working time of some stations, the change of production line layout and the implementation of subsection management etc. After being put in practice, this project takes great benefit for the enterprise, for example, the production capability of production line improved up 61.4%, workers cut down 111, manpower cost saves $922400 every year, and workshop condition is also improved.
