Overlapping student groups - is it possible?

[swilk]

Hi,

This is my first post to this forum, so I would like to say hello to everyone.

I am trying to determine if FET will fit our needs and I am not sure what to do with one of the constraints we have.

The each of the student years in our department are divided in two kind of groups - normal groups and laboratory groups.
Lets say that there are 120 persons on the year.

This year would be divided into 4 normal groups, 30 students each, and 6 laboratory groups, 20 persons each.
So group 1 overlaps with lab1 and lab2, but group 2 also overlaps with lab 2, and lab 3. Please see attached table.
This means that subgroups is not what I am looking for.

Is there any mechanism I could use to mark different groups as overlapping? Eg Group X cannot have any activities in the same time when Group Y has.

Best regards,
Szymon

Hello, and welcome to the forum, Szymon!

You situation is surely easy for FET.

Possibilities:

1) I would prefer this: divide the year. Consider subgroups of 10 students. Then create year Y, with 10 groups: G1,..., G4, LG1,... , GL6. Add in each one the needed subgroups (FET will inform of overlapping groups). I think you cannot use the automatic division of the year Y, but I might be wrong (I am a bit tired of work :-)  )

or, as you wanted:

2) Add a separate activity tag for G and LG activities, and use the constraint activity tags not overlapping. I am not sure if 2 tags will suffice or you need 10. You will add a single constraint of this type.

Please let me know.

I am not sure if your request and my answer (2) will work.

Correction at (2): you might need to add more constraints.

But anyway (2) might not work.

Thank you for your answer. I will give it a try and see if it works.

It is easy...

Create an Year: say Year-1
Create 10 groups: G1, G2, G3, G4, L1, L2, L3,..... L6
Create subgroups:
1) G1L1: common for both G1 and L1
2) G1L2: common for both G1 and L2
3) G1L3:                                 G1 and L3
4) G2L3:                                 G2 and L3

and so on.....

You can use divide year option, but you need to delete lot of unnecessary subgroups manually.
