I want to change the state of a unit and therefore allocate a resource. I don't care how long the state of the unit will stay this way. So, I think the interval for allocating the resource should be rather short and immediate. But since the interval is not defined relative but absolute it could happen that I miss it.
Furthermore I don't want to define a long interval with the first policy because the first block in the interval could be too long and I could block other allocation attempts before I release the resource.
My questions are:
How do I handle the described situation?
What happens when I try to allocate a resource in an interval that lies entirely/partly in the past?
What is the difference between the slot and constraints intervals in the resource allocation RSTType?
