Room Usage

[Teck Hock]

Hi, it is possible to

Can an activity to use only 1 room but have a choice of multiply rooms to choose room?
Meaning - we assign 4 rooms but FET will choose only 1 room.

[Volker Dirr]

Yes. That is exactly why roomS constraint are available in FET. So don't use the room constraint. Just use the roomS constraint.

[Teck Hock]

Like this? It will use one of the 3 rooms available?

Thks

[Volker Dirr]

Yes, the activities with that subject will only use one room out of that three rooms. (If you need more then 1 room for an activity, then please read the help about virtual rooms)

[Teck Hock]

What about this.

I have an activity that need 2 rooms.
Room 1 - has Room A, B and C to choose 1
Room 2 - has Room P, Q and R to choose 1

Possible?

Please read FET -> Data -> Rooms -> Make/edit virtual -> help

[Teck Hock]

Great and thanks for the help.
I have figured out my needs already.

Thks again

Ηi everyone, I am facing the following problem: There is a teaching subject with declared preferred classrooms. This subject is taught by some teachers independently. I want one of these teachers to teach the course in a specific room from the above when it is available. That's how I declared this specific room for the teacher. In the timetable created by fet there are lessons of this subject with this teacher in other rooms while this one is available. What could be wrong?

[Volker Dirr]

Maybe you used a weight below 100%?
Or you added a subject preferred room constraint for that teacher. Teacher (home) room constraints will be skipped, if there are other room constraints related to the activity.
If that doesn't help please attach you file and tell us the name of the teacher, the subject and the room, so we can maybe find the bug.

[geokom]

name of the teacher is Teacher
name of the room is A Room
name of the lessons are Lesson1, Lesson2

[Volker Dirr]

Because you added 2 constraints to that activities, but the teachers home room constraint will be always skipped if you add an other room constraint.

So you have:
------------

Space constraint
Subject preferred rooms
Weight (percentage)=100%
Subject=Lesson2
Room=A Room
Room=208
Room=210
Room=301
Room=302
Room=303
Room=304
Room=305
Room=306

Space constraint
Teacher home room
Weight (percentage)=100%
Teacher=Teacher
Room=A Room

---------------------

FET cares about the first constraint and select randomly one out of that 9 rooms.
FET don't care about the second constraint, since it is a HOME room constraint that is "overwritten" by other room constraints.

HOME room constraints are different from all other constraints in FET. In normal case FET cares about every constraint.
But HOME room constraint are different, they are disabled as soon as there is an other room constraint related to the activity.

Τhank you very much
