| Summary: | In the manufacturing industry, lean manufacturing becomes popular as a beneficial way
in the pursuit of better system efficiencies. The purposes of this study were to identify
waste using lean manufacturing technique, determine causes to the waste through the
value stream mapping method and to propose solution to improve workplace
environment. Asian Composite Manufacturing Sdn. Bhd. (ACM) has been chosen as the
company to conduct case study for this research. ACM is a joint venture company based
in Bukit Kayu Hitam, Kedah, Malaysia owned equally by The Boeing Company and
Hexcel Corporation. The business of the joint venture is the manufacturer of flat and
contoured primary (Aileron skins, spoilers and spars) and secondary ( flat panels,
leading edge, trailing edge and MISC component) structure composite bond assemblies
and sub-assemblies for aerospace industries. There are some waste activities identified
during observation including unnecessary transportation, excessive motions, inventories
and waiting. In order to reduce this waste, some of lean manufacturing tools are used.
Examples are Just-in-Time manufacturing (kanban system, continuous flow and takt
time production planning), 5S, kaizen improvement, value stream mapping and
production preparation process (3P). As a result of the use of these tools reduces lead
time, increase efficiency of value added activities and eliminates some non value added
activities. The tools suggested to be use in this study are pull system, takt time planning,
visual control, kaizen, 5s and continuous flow. The results of this study indicated that
implementing lean manufacturing system can improve the process performance by
eliminating 7 types of waste. The main tool to be used in this study is Value Stream
Mapping (VSM). |
