Max Hours for a room(s)

[Benahmed Abdelkrim]

Hi.
Is it possible to specify the maximum number of hours that a room can be available during?
It is a problem that I did not find a solution or a trick, while preparing the exam schedule using the virtual rooms.
Attached below the FET file.

hmm...Why is that needed?
As a workaround you could add a teacher with a room name instead of a room, but i still don't understand why you need to limit the time in a room. Maybe we can see tricks if you understand why that is needed.

[Benahmed Abdelkrim]

In the attached file teachers were added as rooms, and rooms as teachers. But we want every real teacher (room) to have the same number of hours of work. Can this be achieved?
We have 10 real rooms that have been entered as teachers: S1, S2, .....S10
And 36 teachers were entered as a rooms: T1, T2, .....T36

A virtual room has been added because we need (2) teachers in each real room.

Hi, Benahmed,

A constraint room occupies max time slots is difficult to add, I think. Please allow me to think of your problem and I will let you know as soon I find something.

Please let me know if you are opened to other approaches than yours above (which I will try to find).

yes absolutely..all approaches are acceptable. and Thanks for your attention.

I think I obtained something useful. See the attached file. The activities have only subject. They are allocated to FET days (real slots = 9) and to FET hours (real teachers = 36).

There are maximum 5 activities for a real teacher. There are maximum 20 activities for a real slot. You can choose each pair and put it in a room.

Please let me know.

I attach my .fet file and an example of a solution.

See the activities timetable when you generate.

[Benahmed Abdelkrim]

Useful and practical idea. Thank you so much
But it remains to achieve (2) teachers in each Room. To achieve this, I added 10 activity tags equal to the number of real rooms (10) . I added a time constraint (activities occupies max time slots) that guarantees the maximum frequency of the activity tag in each time slot equal to 2.
with allowing activity tags to be printed in timetables.
I Attach the modified file below.

You are welcome! 

So your additions are only visual, to print each room? Otherwise, I think from my initial solution you could choose any rooms (but they are not printed).

[Benahmed Abdelkrim]

Yes as you described

Good trick... But I think adding the above time constraint (room occupies max time slots) would be better with  using virtual rooms . what do you think?

[Liviu Lalescu]

My method is also good and fast, and unfortunately room occupies max time slots is difficult to implement. And I think you can do more options/things with my method. And it is clearer, in my opinion (I understood your method with difficulty).

[Benahmed Abdelkrim]

I think I found another trick, maybe even better.
The teachers were entered normally. Groups and sub-groups were used as real rooms
I didn't use space constraint. this file is very simple.
I leave you to see it in the attached file below.

Please let me know what you think 

[Liviu Lalescu]

Yes, maybe, but in this case it was you choosing the teacher for each activity, not FET.

[Benahmed Abdelkrim]

Yes, and for a quick introduction to the activities, I used the customized version for Algeria, using a function separately... I think it would be useful if it was included in the official version. What you think?
This trick avoids using the custom version "mapr" Which is unstable.
Now it is easy with this trick. It also prevents the teacher from observing the room more than once during the week
Attached below are some beautiful files that we previously got via FET "mapr". Now it is easy with this trick

[Liviu Lalescu]

1) "Separately" is suggested and in the TODO, but I don't think it has its place in the official FET. It might complicate things and confuse the user. I am sorry. Official FET is for every institution in the world.

2) What trick? Your last one? Yes, but you chose exactly the teachers for the activities, you did not give the freedom to FET to choose.

[Benahmed Abdelkrim]

As for the second point, it is normal, which is not a problem. It is the natural way to introduce activities in FET. This way is very useful because it makes us avoid repeated observing of the room by the teacher during the exam period.
