The aircraft assembly process done in PT Dirgantara Indonesia, the only aerospace manufacturing company in Indonesia, is done in 2 stages: component assembly and final assembly. This research will focus on the final assembly process which is done in the Final Assembly Line (FAL), a fixed process layout assembly system with 4 posts. In each post there are a few tasks that should be done by the operators. As the different tasks require different skills, the operators for each post must be chosen according to those skills as well. The FAL department uses a measure of cycle time as a Key Performance Indicator (KPI). The cycle time is very important for PT DI because they are aiming to produce 4 units of aircraft per year, or a cycle time of 3 months per aircraft. Currently, the cycle time for the department is around 690%, a very high deviation from the target of less than 100%. As such, it is important to design a balanced assembly line for each post (work station) by taking into account operator assignment as determined by their classifications, so that the total makespan of the aircraft assembly process could be shortened. A suitable model for this research is developed by first evaluating other researches about assembly line balancing. Selection of a corresponding model suitable with the real conditions of the FAL department is done from those researches and the chosen model will be modified by designing changes to the model, such as changes in objective function, addition of variables and parameters and elimination of irrelevant constraints.
