the amount of worker service time
must be reduced for compensation. As an example, for
12-machine, the operator service time will be 7.96
minutes and at least 45 seconds of work must be reduced.
Therefore, some unimportant tasks should be eliminated
equal to or greater than a reduction time. Typically, nonvalue
added works should be prioritized and
consecutively eliminated until no further works can be
logically discarded. A work value analysis is shown in
Table III. A list of works including their operation times
are shown in Table IV. Then, all of the alternatives are
simulated by a simulation software program. The
selection criterion is maximum machine utilization and
will be described in details next.
