基于价值流视域下的AIP公司生产流程改善研究(上)

Based on value stream under the horizon of AIP production process to improve research(Part 1)

以提高企业运作效率为核心,选取AIP公司轮胎生产线的优化作为本次研究案例,首先,通过绘制现状价值流图,达到生产线的现状可视化,分析工艺布局与物流和信息流的活动,找出当前生产模式中存在的增值与非增值环节;其次,运用精益思想和工业工程的方法,对生产流程进行分析与改善,引入看板拉动式和连续式生产等方法,以节拍平衡方式进行生产,压缩非增值时间、消除信息阻碍、减少作业人员和在制品库存等,使生产周期及产能得到有效改善;再次,采取工序重组、流程优化等改善手法,对生产流程进行精简,并绘制未来价值流图作为重点改善方向,从而实现生产线的再设计;最后,通过价值流图的前后对比发现:企业产能、设备利用率及生产周期改善显著,在提高产品质量的同时有效地降低了生产成本。

In order to improve the enterprise operational efficiency as the core, the selection of AIP company tire production line optimization as the study case, first of all, through the value stream map drawing status quo, to the present situation of the produc tion line visualization, layout and the activities of the logistics and information flow analy sis technology, find out the current existing in the production mode of valueadded and non valueadded links; Second, the use of lean thinking and method of industrial engineer ing, analyzed the production process and improve, the introduction of kanban pull and continuous production method, such as production, on the basis of the beat balance com pression nonvalue added time, eliminate information block, reduce the homework person nel and wip inventory, etc. , make the production cycle and to effectively improve produc tion capacity; Again, take the process restructuring, as well as process optimization to improve technique, to streamline the production process, and draw the future value stream map as the key to improve the direction, so as to realize the redesign of the production line Finally, through the value stream map before and after comparison found., enterprise pro duction capacity, equipment utilization and production cycle is improved significantly, in impro ving the quality of products at the same time effectively reduce the production cost.
