Research On The Upgrading Of BH Assembly Line

BH is a Beijing-based Sino-foreign joint venture passenger car production enterprises,production capacity in a saturated state.Faced with the rapid growth of China's auto consumer market,improve production capacity to expand production capacity,in the highly competitive Chinese auto market to seize the initiative,as BH company's current primary task.To seize the market opportunities at the same time improve the competitiveness of products,reduce production costs and improve production efficiency has become the main task facing BH companies.Based on the lean production theory,this paper analyzes the present situation of X factory assembly plant,and analyzes the factors that affect the expansion of production line from the aspects of process layout,logistics layout and production equipment,and find out the bottleneck of production line speed Where.First of all,through the analysis of the layout of the process,the overall layout of the process to adjust the part of the production process to adjust the factory outside the straight line,the assembly line on the plant to improve the layout of the process,while the remaining bottleneck of labor-saving equipment to adjust,Calculate the optimization of production line balance.According to the adjustment of the layout of the process,the logistics layout analysis,the mixed material pulling mode adjustment,increase ONE-KIT system for SPS material supply mode,for the factory outside the direct sequence adjustment,the JIS supply way layout adjustment,At the same time re-planning of the material flow routes in the factory.After the above transformation,compared with the transformation before and after the production capacity,integrated operation rate,site saturation and staffing,etc.,to assess the production line to upgrade the effect of upgrading.The research of this paper not only provides reference for BH company to expand production capacity,but also provides some reference for other domestic manufacturers.
