In order to improve the assembly efficiency of Airbus A220 aircraft door production line and reduce the labor and man-hours

firstly

the assembly time data of door production line was measured by time measurement method based on lean thinking in this paper

and the number of tooling needed to improve the production capacity is determined; Secondly

the Spaghetti diagram was used to analyze the logistics trend of operators in the assembly process

and the possible waste phenomenon is analyzed. Based on the waste phenomenon and the characteristics of door assembly process flow

the door production line is arranged according to the principle of product clustering. At the same time

the layout form of the whole station serial and the local bottleneck station parallel are determined referring to the IE (industrial engineering) method

then the door lean production line is established. Finally

3D rendering was conducted for the overall layout by 3ds Max software.
