Optimization of AIP Production Process from the Perspective of Value Stream

With improving the enterprise operational efficiency as the core, the paper takes tire production line optimization in AIP company as a case study. First of all, through drawing the current value stream map, the present production line is visualized, and layout and the activities of the logistics and information flow is analyzed. Therefore, value-added and non-value-added links in the production mode can be identified; Secondly, based on lean thinking and industrial engineering, the production process is analyzed and improved, the introduction of kanban pull and continuous production, and production based on beat balance is aimed to reduce non-value added time, eliminate information block, streamline the personnel and WIP inventory, etc., thus improving the production cycle and capacity. After that, process restructuring and optimization is adopted to improve technique, streamline the production process, and draw the future value stream map so as to redesign the production line. After a comparison of the previous and present value stream map, it is pointed out that enterprise production capacity, equipment utilization and production cycle is improved greatly while the production cost is reduced effectively. Its application has proved that value stream map analysis is an effective way to improve the efficiency of enterprise production, and it can serve as a powerful tool for enterprises to implement lean manufacturing. Therefore, it is worthwhile to promote its application.
