Research on product production process optimization based on value stream theory

Abstract

Value flow technology is used to study problems including poor balance in production line and excessive work-in-process inventory during the production process of plasma display panels. Firstly, the work measurement technology is used to find relevant data for calculation and draw status picture of product value flow. In addition, the unreasonable places and waste phenomenon of products in the production process are found. Then, for these problems, industrial engineering and lean thinking is used to optimize product production process from various aspects. Moreover, the future value flow chart is drawn. The results have shown that comparing with the functional IE, after using the Value flow technology to optimize the product manufacturing process of the plasma display panels, numerous non-value-added activities in the production process are removed to increase balance rate of production line, shorten delivery cycle and further decrease production cost.
