摘要 在全球经济衰退和中国经济转型的背景下，传统制造业面临巨大压力，随着中国人力资源成本上升和市场竞争激烈，企业的利润空间越来越小。因此，多数企业在市场饱和情况下开始重视成本的控制。本文基于单件流思想对安亿公司电机生产方式和生产线进行分析，从而发现公司生产线上在制品过多，生产中存在生产流程混乱以及库存浪费的问题的问题。针对公司这些问题，本文主要从单元布局、生产工序平衡来优化生产线，并代入拉式生产和看板管理和快速换模理念改善公司装配车间与铸造车间生产不衔接的问题，最终使得公司能够按单件流思想来生产，降低公司成本。 58671

Abstract Under the background of economic transformation of China and global recession, the traditional manufacturing industry is facing huge pressure. With the rising of human resources cost and intense of market competition, profit of enterprises becoming smaller and smaller. As a result, most enterprises paid attention to the control of cost under the condition of market saturation. Based on one -piece flow,the paper analyze the company's production and motor, which found that the company production line has too many products, The presence of confusion of the production process and problems of waste inventory. To deal with these problems,the paper transform the production line into single piece flow production. The paper optimize line, which mainly from the layout of cell production and the balance of production process. Through the pull production and Kanban management and SMED to improve the problem of pergence of assembly workshop and casting workshop production. The final result is that the company can produce according to the ideal of single piece flow, which lead to reduce cost of the company.
Keywords: Pull production; One-piece flow; Cell layout; Step balance; SMED
