Abstract: Taking S product line from X company for research object,the product family was selected according to the mode of product quantity analysis,and the current value flow diagram of S product line was drew,which could analyze the wasting problem in product process.The improvements on “water spider” feeding mode,5S management,stream-lining and better layout were proposed based on value flow analysis,and two systematic research on improving value flow was implemented.The practice showed that the efficiency of S product increased by 15.5% after the first improving research of “water spider” feeding mode,and raised 11.7% again after the second,and the value-added ratio was raised from 3.7% to 5.21%,which had brought remarkable efficiency improvement for company.

Key words: value stream, “water spider&rdquo, distribution, stream-lining, value-added ratio, lean optimization

摘要： 为了进一步以价值流思想持续消除生产线非增值部分来提升生产效率,选择S生产线为研究对象,根据产品数量分析方式选定产品族并绘制出S生产线的价值流现状图,然后分析其生产过程中存在的浪费问题。运用价值流分析方法,提出“水蜘蛛”配送方式、5S管理、流线化和优化布局等改善方案,并进行两次较为系统的价值流改善研究。实践表明,“水蜘蛛”配送方式改善研究能够使S生产线的生产效率提高155%;采用系列化改善研究措施能够使生产效率提高11.7%,增值比从3.70%提高到5.21%,明显改善了公司效益。
