Research questions Anyi company implements lean production of one-piece flow
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
