Research on the Process Improvement of AIP Production Based on Value Stream

In order to improve the enterprise operational efficiency as the core,the optimization of AIP company tire production line was seleted as the study case. First,through the value stream map,the present situation of the production line was visualized; the activities of the logistics and information could be analyzed by technologies; the current existing in the production mode of value- added and non value- added links could be found. Second,by the use of lean thinking and method of industrial engineering,the production process was analyzed and improved. Through the introduction of kanban pulling and continuous production methods,such as,balancing compression non- value added time,eliminating information block,reducing the homework personnel and wiping inventory,etc.,the production cycle and producing capacity could be effectively improved. Third,by the process restructuring,as well as process optimization,techniques would be improved; the production process would be streamlined,and drawing the future value stream map would be the key to improving the direction,so as to realize the redesign of the production line. Finally,through comparison,the follows were found: enterprise production capacity,equipment utilization and production cycle were improved significantly.At the same time when improving the quality of products,the production cost would be reduced effectively. Practice has proved that value stream map analysis technology is an effective way to improve the efficiency of enterprise production,and it is a powerful tool for enterprises to implement lean manufacturing,as well as worthy of reference for the enterprise and promotion.
