I B.A./Krim,
yes, your solution has three activities 4 times but the three activities must be only third rooms (the highest grade) and not lower grades.
I hope it's clear.
Thanks

I didnt' get you.. What do you mean in details? Registra :-) Giovanni

Thank you very much Volker,
I'll do ad  you suggested and I'll talk with the teachers.
I've perfectly understood your simply method.
I'm very happy.
I have now three different method to resolve the problem but your last one a think is good enough.
Than you again
Regards

I Volker,
thank you for your all suggestion.
Unfortunately the timetable is still not correct. As you can see for MO subject (i.e. physical education) the 7 hour is still usedby a 3 room.
What I'd like to have is:
1) two rooms in each hours  (7 hour not used at all) except in 4 hours.
2) only in 4 hours I need three 3 rooms (7 hour not used at all), for example 3A, 3C, 3F; 3F, 3H, 3G ...... (just example).
Thanks a lot for your interest.
Regards
Giovanni

Ciao Valdo,
con il prezioso aiuto di Liviu ho risolto il problema. Metto il file in attach per futuri usi.

Hi Volker, I have added all the other activities and enabled the constraints.
The result is not good yet because I have in several case that the 7 hours is used.
Attached the file.
Thanks

Hi Liviu.

Hi Vangelis Karafillidis,
Right !! The only added information is that the 4 times (hours) with three lessons (all third rooms) simultaneous must be all third rooms.
Thanks

Valdo scusami, le otto terze che mi servono per il vincolo di tempo -> attività -> un insieme di subattività non sono concomitanti, non avranno il tag palestra. Giusto?

OK Valdo, mi metto al lavoro e ti faccio sapere allegando il file.fet.

A presto e grazie.

Ciao Valdo,
grazie per la risposta.
Quindi se ho capito bene, avendo 11 attività per le terze, quindi 22 subattività (1 ora + 1 ora). Nel vincolo di tempo -> attività -> un insieme di subattività non sono concomitanti, nel riquadro a dx devo mettere sempre 4 subattività. Ad esempio le due subattività  per la 3A e le due per la 1A, poi ancora un'altro vincolo con le due subattività  per la 3A e le due per la 1B e così via con le altre prime e seconde. Essendo 11 prime e 10 seconde, allora dovrò settare 21 vicoli. E poi ripeto per tutte le altre terze.
E' corretto?
Resto in attesa di un tuo riscontro così inizio a lavorare e ti faccio sapere.
Grazie infinite
Giovanni

Hi Volker,
atteched file for method a.
The time table is not what I want. Same hours with one activity only. Only two times, trhee ativities but not all third rooms.
Probably I'm wrong the time constraint.
Please can you check?
Thanks a lot indeed.
I'm waiting for your reply.
Kind Regards

Hi B.A/krim,
Thanks for the file but after 20 minutes any solution had been found (62/64).
Have you run the timetable? How many time for the solution?
Thanks a lot
Regards

Hi Liviu,
I have done as you suggested. I set four teachers and I have maintained all the setting that you have done in your file.
After 40 minutes no solution has been found by FET.
Attached the file.
Please could me tell me where I'm wrong?
Thanks a lot indeed
I'm waiting for your reply.
Kind Regards :-)

Hi Volker, I have tried method b but the timetable is not running.
File attached.
