Flexibility that teachers can teach on different courses

[infoo_]

Hello

I have "Subject A" that has to be teached on courses 3C, 4C and 5C simultaneosly (for example at hour 3 of Mondays). We have available one teacher for each activity.

However, it doesn't matter where these teacher can teach: Teacher 1 can teach Subject A on 3C, 4C or 5C. The same for Teachers 2 and 3.

I can say that for example:

Teacher 1 teachs Subject A on 3C at hour 3 on mondays
Teacher 2 teachs Subject A on 4C at hour 3 on mondays
Teacher 3 teachs Subject A on 5C at hour 3 on mondays

But it is also possible that:

Teacher 3 teachs Subject A on 3C at hour 3 on mondays
Teacher 1 teachs Subject A on 4C at hour 3 on mondays
Teacher 2 teachs Subject A on 5C at hour 3 on mondays

etc.

Is there any way to achieve this?

Thanks!

I think there are more ways to do this:

1) Add an activity with the 3 teachers and the 3 students sets. Use a virtual room if you need this activity to occupy 3 rooms.

2) Add 3 dummy activities, one for each teacher (no students) and 3 dummy activities, one for each students set. Then 1 constraint activities same starting time.

3) Simply add 3 activities and a constraint activities same starting time.

Hello

I posted this in a "Teacher view mode", but we have same results if we change courses distribution.

For example:

Teacher 1 teachs Subject A on 3C at hour 3 on mondays
Teacher 2 teachs Subject A on 4C at hour 3 on mondays
Teacher 3 teachs Subject A on 5C at hour 3 on mondays

But it is also possible:

Teacher 1 teachs Subject A on 5C at hour 3 on mondays
Teacher 2 teachs Subject A on 3C at hour 3 on mondays
Teacher 3 teachs Subject A on 4C at hour 3 on mondays

or:

Teacher 1 teachs Subject A on 4C at hour 3 on mondays
Teacher 2 teachs Subject A on 3C at hour 3 on mondays
Teacher 3 teachs Subject A on 5C at hour 3 on mondays

etc.

Is the same procedure Liviu? Which is less painful to implement?

[Volker Dirr]

hmm.... If you want to have less data to input, then just place all teachers and all students into a single activity (with a virtual room constraint added, so the correct number of rooms will be taken).

[Liviu Lalescu]

It is the same.

Yes, I would follow Volker's preference.

Thank you guys!!

I hope it works. Now I have an urgency that I can't solve (see here: https://lalescu.ro/liviu/fet/forum/index.php?topic=5492.0), so I'll try Volker's solution when I fix it first.

I thought FET would assign a teacher for each time slot, but it seems it creates an activity with teachers separated by comma (meaning that any of those teachers can teach that subject).

I know it is not a problem, but I thought FET would assign just one teacher for each activity, not the 3. But it's okay.

In my schedule I would write once each teacher. I think there would be no problem.
