Optimization of Avionics Assembly Line Based on Lean Line Balance

At present, due to the fact that avionics product assembly is completed, small in bulk and varied in categories, the traditional manual avionics assembly line should be optimized to improve the production efficiency based on the lean production theory. A way has been found to improve the assembly process by the analysis of value flow, work hour balance, and process standardization, which is in accordance with the process of avionics products. The constraint condition includes assembly process, space occupation and number of personnel. At first, we find the improvement target of production line by using value stream analysis. In addition, assembly process is improved through time balance analysis and operation standardization. On the basis of improving the process, the production line is rearranged and the assembly equipment is improved by establishing material transfer line and designing circulation material box. In the end, the production efficiency of the production line increases by more than 60%. It will be helpful for the modern production of avionics products.
