| Summary: | PT Y, which is engaged in the production of NX type aircraft, is currently targeted to complete eleven aircraft within two years. In other words the cycle time for making an NX plane is 300 hours. One unique characteristic in NX aircraft assembly is the complexity of each element of work. This causes one work department to be done by multi operators. The time of completion of an element of work will depend on how many operators are assigned to complete the work sheet.
Researches related to the design of assembly lines generally have an objective function to minimize the time difference between work stations. This research focuses on the design of assembly lines for work elements that are long and can be done by multi operators.
This study aims to develop an assembly line design model where each element of work can be done by multi operators. The results of the model trials produce a feasible solution and meet the specified cycle time. The model has limitations in computational time so that not all results are optimal. Computational results show the number of operators from 80 to 60, the cycle time from 1018.04 to 278.5. SI from 3007.78 to 554.3 the number of stations from 14 to 16. |
