基于 VSM／A 的单件工程式生产精益分析

摘要

To implement lean production in an engineer-to-order enterprise, first, VSM/A is used to draw the current value stream map of the rotor production in a HT turbine factory , finding out the non-value-added time in the production .Secondly , by introducing lean production ideas such as Kan-ban pull system and balanced production and JIT logistics , the non-value-added time is reduced and a future value stream map is drawn.Finally, through the implementation of the program , the value-added time is reduced by 71 h, the non-value-added time shortened by 28 days, the distance reduced by 1 756 m, the value-added proportion increased by 4 .48%, which proves that using the value stream mapping technology to optimize the lean production in an engineer-to-order enterprise has good practical value .%为在单件工程式生产企业推行精益生产，应用VSM／A绘制HT汽轮机厂某转子生产的现状价值流图，确定生产中存在的非增值环节。应用拉动式看板、均衡生产、准时化物流等精益生产理论，缩短非增值时间并绘制未来价值流图。通过方案实施，增值时间缩短了71 h，非增值时间缩短了28 d，搬运距离缩短了1756 m，增值比增加了4.48％，证明了应用价值流图技术对单件工程式生产企业进行精益分析具有良好的实用价值。
