Let us assume that FactoryTalk Scheduler is going to schedule an operation that requires a
primary resource that is available 24 hours a day and currently is not being used during
Days 1 or 2. This operation also requires two units of labor during its six-hour operation
time. If the operation were available to start on or before 9
AM of Day 1, it could be
scheduled during the first day. For example, if the operation could start at 8 AM , it would
be scheduled from 8 AM to 2 PM , as shown below.
Adjustable Pooled resources not only allow spanning, but they also allow the number of
labor units to vary, which will pace the operation. Thus, Adjustable Pooled resources are
often used to model resources where the pace or efficiency of the operation is based on the
number of workers currently available. Again, this is best illustrated using an example.
Let’s assume that we want to schedule the same six-hour operation as before. If the
operation could not start until 1
PM on Day 1, it would be scheduled from 1 PM to 10 PM ,
