Therefore, some unimportant tasks should be eliminated
equal to or greater than a reduction time. Typically, non value 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.
