Title: StudentsSetMaxHoursDaily
Post by: HappyIX on April 21, 2013, 05:10:32 PM
Hello,

I'm trying to add a constraint to limit the number of lessons for a class (e.g., 1.A) per day (e.g., 3 lessons per day is maximum).

Let's suppose I use "Max hours daily for a students set" on class 1.A. Now let's suppose that the class is divided into subgroups A1 and A2.

Does FET handle the situation correctly?

Example:

Classroom / periods      1            2           3             4
=====================================
Room1                       || 1.A   ||   1.A  ||  1A(A2)  ||  1.A       

The example shows a situation when the class 1.A (or the subgroup 1.A(A2))  in Room1 attends some lessons.


The question is if FET sees this situation as violation of the constraint "Max hours daily for a students set 1.A". In my opinion it should but I need to be certain.

Thank you!

Of course it is a violation. Generally, you could make some test files to check.

The constraint is broken up for each students subgroup, and so is each activity. If they have common subgroups, the constraint applies.
