| Summary: | PT Dirgantara Indonesia (PT DI) is one of the companies belongs to Badan Usaha
Milik Negara (BUMN) that moves into aircraft industry. CN-295 airplane is one of
primary products from PT DI. In the production process of it, this airplace has
three main processes, those are detailed part manufacturing (DPM), component
assembly (CA), and final assembly line (FAL). From those three divisions, CA is
the divison with the highest actual cycle time, that is four months. It makes the
requirement to produce four airplanes each year can not be achieved. Assembling
of rear fuselage becomes the reason of the high actual cycle time. PT DI has
implemented panelization system in order to increase production capacity so it can
accomplish the desired cycle time, that is three months. Nonetheless, the actual
condition has not able to prove which work method that is used capable to produce
desired number.
This research aims to design new work method for assembling of rear fuselage so
it can achieve desired cycle time and assign worker team for doing work operations.
Assignment for operation processed considers the workload balance. The workload
is total time of operations assigned for a worker team. The proposed work method
is assembling together from frame 25-30 and frame 46-31 and also moving partial
of operation from jig 3 to jig 2. The mathematic model that is used to look for the
assignment of worker team in this proposed work method is mixed integer linear
programming with objective function to minimize workload balance between
worker team. The result from computation process proved that actual cycle time in
proposed work method is 985.6 hours or 2.8 months. The workload balance
between worker team is 15.383 hours. There are three teams with the compositions
consist of 3 assembly operator level 3, 3 assembly operator level 2, 3 sealers, and
3 painters. Meanwhile in current condition, there are three teams with the
compositions consist of 2 assembly operator level 3, 4 assembly operator level 2, 3
sealers, and 3 painters. |
