planning oral exams

[forstera]

Hello Liviu,

I'm going to try explaining my purpose  :

An exam lasts 15 minutes and there is no break between exams.
So teachers do 3 exams followed by a 15 minute break to discuss and mark.
For this reason, we cannot, for example, put 2 exams in the same class and then change teachers directly. The change of teacher must be done during a break.
This is valid for the French and German exams. For the maths exams, there are 4 sessions followed by 1 break session.

let me know if this is a litlle bit more clear with that esplanation

Thanks very much for your help
Kind Regards
Arnaud

Hello, Arnaud,

Please let me think.

I think you do not refer to teachers min 1 gap between room changes, but to the more elaborate problem of a room which must remain empty after a session of at most 3 (or 4) exams with the same team of teachers.

By class you mean a FET room?

[forstera]

Yes, you're right, by class is a FET room, exactly.

For the while this the constraint that makes me a hudge problem ..

[forstera]

Yes, I tried to add this constaint (1 gap between room change) but this didn't solved my problem because they usually stay in the same room ...

Hello, Arnaud,

I thought some more: it could be possible by a customization. Please let me know if you are interested. I am thinking of a hard-coded constraint of kind: before and after an activity which occupies room R, in room R there must be the same teacher or empty. We can make this constraint hard-coded for each room, or add a constraint with dialogs and add this constraint in the constraints list (which is more tedious work and probably unnecessary, only cosmetic).

I will now leave for a couple of hours, but if your matter is urgent please let me know and I can begin working earlier.

Hello Liviu,

Wow it would be great  ! Yes,
the only problem we have, I apologize for that, is a time constraint. We have to send today the postal letters to the students ...

So let me know if you think we can do it.
And of course we want to pay for that ...

Thanks so much for your help    

[Liviu Lalescu]

OK, I'll begin work now. I hope I can do it.

[forstera]

thanks so much !
at the same time we will start the work by hand in case ...

[Liviu Lalescu]

OK, I hope I did it. I attach a timetable. I will now compile your Windows version (need at most 15 minutes) and put it online.

Please let me know.

[forstera]

Wow ...
our entire secretariat follows you with great satisfaction ..

[forstera]

it sounds perfect !!
In the meantime, we received a new constraint but this is just a teacher who has not available times... I can't wait to test this. 

[Liviu Lalescu]

I have just put it online, please get it from https://lalescu.ro/liviu/fet/download/custom/forstera/

I will wait at home online for any problems.

[Liviu Lalescu]

Don't forget that I did not add the not available constraints from your file. Please examine my file for your missing constraints.

[forstera]

Thanks very very much Liviu,
testing now...
Yes, I'll have to add this new constraint

[Liviu Lalescu]

You might want to add also teachers max 1 room changes per day, if needed.
