Modeling of Assembly Line of FinderUnit for Camera

The Dissertation consists of six main divisions excluding Abstract and Appendix. The
main divisions are Introduction, Literature Review & Theory, Methodology, Results &
Discussion, Conclusion and References. The study was carried out to model the assembly
line of finder unit of camera by using WITNESS software. It was also to perform
sensitivity analysis in order to propose the best layout, besides, to be familiar with
WITNESS software by using its basic and advanced features. Three main measurements
were highly evaluated; production rate, throughput time and number of WIP. The study
scope was on particular assembly line of the finder unit. It was a component in a camera
used to look through when the camera was in hand-to-view position. Simulation role was
to evaluate alternatives to support strategic initiatives or support better performance at
operational and tactical levels.
The following were studied in supporting the project;
(a) Manufacturing System, (b) Facility Layout, (c) Manual Assembly Line,
(d)Automated Assembly Line, (e) Single Station, (f) Time Study, (g) WITNESS
software.
There were three types of layouts proposed in the project; in-line manual assembly line,
in-line semi-automated assembly line and single station. The method involved during the
simulation were introducing the elements, entering the input and output rules, editingthe
details of the elements, running the simulation, obtaining the reports and analysis. The
main tools used were WITNESSsoftware and stopwatch. Based on the simulation it was
found that overall, the setting station was the busiest station for almost all designs
compared to other stations. Some of the stations also acquired idle and blocked
percentages. The best production rate was produced by Design 1 with additional number
of setting station, 27.1 units/hr whereas the throughput time was 2.22 minutes. However,
the number of WIP was very high that was 78 units. In conclusion, the modeling of
assembling lines was successfully performed within the allocated time. The use of the
WITNESS software in the project helped much in modeling and sensitivity analysis. It
was recommended for continuation to include more advanced and attractive display
features, and improve the current system in term of increasing the production rate and
reducing the WIP.
