Downtimes and Preemption

ProModel uses priorities in conjunction with resource or location downtimes to determine which defined downtime takes priority. Downtimes with priorities that are 99 or less do not interrupt or "preempt" the activity, but begin after the current process completes. Downtimes with a priority of 100 or higher preempt the current activity. After the downtime, the activity resumes from where it left off.
