Resources

Regular Rate This field specifies the cost per unit of time for a resource used in the model. You can use expressions in this field (evaluated at translation) to set the rate or change it using SetRate. For more information on the SetRate operation statement, see SetRate.

Per This pull-down menu allows you to set the time units for the Regular Rate. Times may be in seconds, minutes, hours, or days as shown here.

Cost Per Use This field allows you to define the actual dollar cost accrued each time you use the resource (i.e., the minimum usage cost). The cost per use updates when you obtain the resource and ProModel accepts expressions in this field (evaluated at translation).

Please note

Since ProModel counts a preemption as a use, if you preempt a resource from an entity, the usage cost applies to the resource only when it returns to the entity.
