| Abstract | The main purpose of this study is to redesign a production
line from single model line basis to mixed model line basis. The
plant concerned manufactures television sets in which most of the
parts I components are electrical in nature.
The design of mixed model assembly line is considered when
the numbers of models exceeds the numbers of assembly lines and
it is desired to keep every product exceeds the number of
assembly in production rather than make batches intermittently
for inventory and changeover time. However, the disadvantage
resulting in the ever flow of work and consequent station idle
time I or congestion of semi-finished products.
The steps of this study are : (i) Investigating the existing
process in the television assembly plant by application of
Hoffman single model line balancing technique. (ii) Adapting
single model line balancing techniques to mixed model line
schedules. (iii) Applying Dar-El and R.F. Cother sequencing
algorithm to determine the line length for no idle time and
operator interference. (iv) Applying the R.C.Wilson & F.Z. Wang
sequencing algorithm to find out the amount of idle time and
utility work of the three designs (a) moving belt with fixed
items, (b) moving line with removable items, (c) moving line with
accumulation. (iv) Comparing the two sequencing algorithm
mentioned above.
A comparison between the existing production line and the
mixed model line shows that approximately 7.4% of labor costs can
be saved. However, in line sequencing, the large amount of idle
time and utility work resulting in moving line with fixed and
removable items; the large number of accumulation for no blocking
degrades the line performance significantly. Hence, the mixed
model line is not recommended in this case study. |
