Close the Operation Constraints window and scroll down the on-time orders until you find
the SHP Red 6 order. Click on this order and then double-click on the single Operation 10
for this order. This operation requires additional resources (two Labor resources) and
materials as shown below.
The Resource Utilizations show values of 82% for Assembly and Pack Area 1 and 84.3%
for Labor. These values are calculated only for the time that the operation is waiting for
the primary resource, the Assembly and Pack Area 1. In this case, that would be from the
order release date (2/18/03 11:00
PM , see order attributes) to the Setup Start time. The
order release date is used for this calculation because this is the first operation for this
order. If the selected operation is not the first operation, it would use the Teardown End
Time of the predecessor operation for this calculation. Also note that these values do not
include any time when the resource was unavailable. Also recall that there are three labor
resources available each day. This would imply that the operation might not have been
scheduled earlier due to the unavailability of two labor resources. However, if you look at
the Sequence overview for that time period, you will notice that although the Labor is
highly utilized for that time period, there are actually two labor resources available
starting at 7:03 on the day the operation is scheduled. Thus, the unavailability of labor is
not the cause for the delayed start of the operation.
