How do I assign Resource Priority?

There are 10 levels of priority values: 0 – 99, 100 – 199, 200 – 299 . . . 900 – 999. 0 – 99 is the only non-preemptive level.

Preemption means that the current work being done by a resource will be interrupted in order for the resource to go to the location of the preemptive GET. After that higher priority work is complete, the resource will return to the interrupted location. Preemption will occur only when the value of the calling priority is at least one level higher than the resource’s current priority.

The calling priority is at least 100 higher than the resource’s current priority.

For example, if a resource is working at a priority of 50, then a priority call of 150 will be required to perform a preemption. The 150 GET will be completed before returning to the initial 50 GET.

Using a priority which is 300 or higher will bring a down (or off shift) resource back on-line (or on shift).

Resource Priority, Shifts, and Interrupt

The Resource priorities, interrupt, shifts, and ‘Interrupt current activity to go off shift or on break’ can be used in a model together, the following restrictions apply.

  1. A resource priority of more than 100 is an interrupt priority, meaning that if a resource is working on a task that has a lesser priority the resource will leave that task and start working on the priority that is 100 or more.
  2. If the resource priority is less than 100, but it is higher than the other task the resource is working on, the resource will not leave the task its working on, but will complete it and then come to work on the task with greater priority.
  3. If ‘Interrupt current activity to go off shift or on break’ is checked on shift of the resource, this will mean that the ‘Interrupt current activity to go off shift or on break’ has a priority of 299. The resource will leave any task its working on and go offline.
  4. An interrupt priority that is used to have the resource leave the task its working on, and start working on another task will work with ‘Interrupt current activity to go off shift or on break’ if the priority is set to less than 199.
  5. An interrupt priority of greater than 199 will keep a resource online, even if its scheduled to go offline and ‘Interrupt current activity to go off shift or on break’ is checked.
  6. An interrupt priority of greater than 599 will bring back an offline resource online, even if its offline and ‘Interrupt current activity to go off shift or on break’ is checked.
