Application Of Value Stream Mapping In The Manufacturing Process Of Automobile Seat

With the continuous rising of price of raw materials and continuous falling of price of cars, it is important to consider how to reduce cost for automobile industry. In order to eliminate all kinds of waste in manufacturing process, reduce cycle time, and improve productive efficiency and quality of products, it is necessary to analyze the manufacturing process using value stream mapping, and solve existing problems with IE tools. In this thesis, Shanghai Intier Jiao Yun Automobile Parts Co., LTD will be taken as the research example. This work presents that how to reduce cost, improve quality, satisfy customers and promote the company's competence through building up a Pull System and carrying out a series of quality improvement and control activities.A product line of Polo basic front seat framework is studied in this thesis. The current value stream mapping is firstly drawn based on the data collected from production information, process, inventoy, and efficiencies of equipments. The wastes in manufacturing process are exposed through the value stream map, which provide the direction for further improveing. In this case, inventory and quality are the most important factors to improve. The pull system is then built based on the Kanban. The process of Kanban operation is given and the quantity is calculated. In quality improvement, quality employment function (QFD) and failure model and effect analysis (FMEA) are used and the integration model of QFD and FMEA are given. Finally the effect based on the improvement is evaluated and the conclusion is given.
