The data in Table I and V are utilized in the
simulation software program. It is found that the machine
utilization of 14-machine provides a maximum value of
96.09 percent. Therefore, this choice will be selected
although the worker utilization is 87.59 percent which is
the lowest among all alternatives. The main reason is that
the actual operator service time after work elimination is
much lower than the calculated one. The longer operator
idle time is ensued. The result is therefore summarized in
Table VI.
