We have the following scenario:
Elevator A is on Floor 1, with both the Elevator Door
and the Floor Door open. Someone enters the elevator and presses
the button for Floor 2. The elevator controller (System) needs to
perform several tasks to bring the passenger to the second floor.
Some of these tasks may be performed either simultaneously
or in either order, so these tasks should be given the same order
number. However, some tasks must be performed before other tasks.
For all of the task(s) that should be performed first, give the
order number 1, then assign 2 to the next task(s), and so on.
There may also be tasks which are not necessarily performed in
this scenario.
