Research On Process-Optimization And Balancing-Analysis Of Body-in-white (BIW) Production Line

The car body-in-white (BIW) manufacturing process is very complicated, and numerous kinds of production resource are concerned. So the configuration of the production resource affects directly the quality and efficiency of the assembly line. But the measures and theories used by most domestic car makers are comparatively behind the times, so it is necessary and urgent to present a scientific and reasonable method.Based on the analysis of correlative technologies at home and abroad, the PASSAT B5 assembly line technical data and functional demands had been analyzed, and then a new planning method was developed. On the basis of this, the influencing factors on resource quantities and the validity of Markov Chain were analyzed, and then a resource quantities forecast model was established.On the basis of theoretical analysis, the "BIW Production Resource Planning System" was developed and the scheduled functions were realized. These functions include: searching production resource, forecasting resource quantities, assigning resource, analyzing the assembly line balance and so on. At last, the theoretical correctness and feasibility of the system were proved by cases.The research has not only important practice significance on improving the method of BIW assembly planning system but also a certain referenced value to design a new production line.
